UNITED AIRLINES HOLDINGS, INC. AND UNITED AIRLINES, INC.
COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.
The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations for interim periods presented. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the "2023 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand and were better than its first and fourth quarter financial results.
NOTE 1 — REVENUE
Revenue by Geography. The table below presents the Company's operating revenue by principal geographic region (as defined by the U.S. Department of Transportation) (in millions):
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Domestic (U.S. and Canada)$8,761 $8,417 $16,434 $15,584

Latin America1,346 1,273 2,791 2,589 
Pacific1,602 1,259 3,190 2,373 
Total$14,986 $14,178 $27,525 $25,607 
Advance Ticket Sales. The Company defers amounts related to future travel in its Advance ticket sales liability account. All tickets sold at any given point in time have travel dates through the next 12 months. The Company estimates the value of Advance ticket sales that will expire unused ("breakage") and recognizes revenue and any changes in estimates in proportion to the usage of the related tickets. To determine breakage, the Company uses its historical experience with expired tickets and certificates and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns.
In the six months ended June 30, 2024 and 2023, the Company recognized approximately $5.0 billion and $4.6 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods.
Ancillary Fees. The Company charges fees, separately from ticket sales, for certain ancillary services that are directly related to passengers' travel. This includes fees for baggage, premium seats, inflight amenities and other ticket-related fees. These ancillary fees are part of the travel performance obligation and, as such, are recognized as passenger revenue when the travel occurs. The Company recorded $1.2 billion and $2.2 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2024, respectively. The Company recorded $1.0 billion and $1.9 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2023, respectively.

Frequent Flyer Accounting. The table below presents a roll forward of Frequent flyer deferred revenue (in millions):

Non-travel miles redeemed(27)(26)(66)(57)
Total Frequent flyer deferred revenue - ending balance$7,353 $7,024 $7,353 $7,024 
In the three and six months ended June 30, 2024, the Company recognized, in Other operating revenue, $0.7 billion and $1.5 billion, respectively, related to the marketing, advertising, non-travel miles redeemed (net of related costs) and other travel-related benefits of the mileage revenue associated with our various partner agreements including, but not limited to, our JPMorgan Chase Bank, N.A. MileagePlus co-brand agreement. The Company recognized $0.7 billion and $1.3 billion, respectively, in the three and six months ended June 30, 2023, related to those agreements. The portion related to the MileagePlus miles awarded of the total amounts received from our various partner agreements is deferred and presented in the table above as an increase to the Frequent flyer deferred revenue. We determine the current portion of that account based on our estimate of expected redemptions in the next 12 months.

Cash and cash equivalents and Restricted cash (current and non-current)The carrying amounts of these assets approximate fair value.
Short-term and Long-term investmentsFair value is based on (a) the trading prices of the investment or similar instruments or (b) broker quotes obtained by third-party valuation services.
Long-term debtFair values are based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities.
Equity Method Investments. As of June 30, 2024, United holds investments, accounted for using the equity method, with a combined carrying value of approximately $231 million. Significant equity method investments are described below:
•Republic Airways Holdings Inc. United holds a 19% minority interest in Republic Airways Holdings Inc., which is the parent company of Republic Airways Inc. ("Republic"). Republic currently operates 65 regional aircraft under capacity purchase agreements ("CPAs") that have terms through 2035.
•CommuteAir LLC. United owns a 40% minority ownership stake in CommuteAir LLC. CommuteAir currently operates 53 regional aircraft under a CPA that has a term through 2026.
•United Airlines Ventures Sustainable Flight Fund (the "Fund"). United holds, through its corporate venture capital arm, United Airlines Ventures, Ltd., a 33% ownership interest in the Fund. The Fund is an investment vehicle designed to invest in start-ups developing technologies focused on decarbonizing aviation and its associated energy supply chains, including through research and production, and technologies associated with sustainable aviation fuel (SAF).
Other Investments. As of June 30, 2024, United has equity investments in Abra Group Limited, a multinational airline holding company, JetSuiteX, Inc., an independent air carrier doing business as JSX, as well as a number of companies with emerging technologies and sustainable solutions. None of these investments have readily determinable fair values. We account for these investments at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. As of June 30, 2024, the carrying value of these investments was $423 million.
Notes Receivable. As of June 30, 2024, the Company has $86 million of notes receivable, net of allowance for credit losses, the majority of which is from certain of its regional carriers. The current portions of the notes receivable are recorded in Receivables, less allowance for credit losses. The long-term portion of the notes receivable is recorded in Investments in affiliates and other, less allowance for credit losses on the Company's consolidated balance sheet.
NOTE 7 — COMMITMENTS AND CONTINGENCIES
Commitments. As of June 30, 2024, United had firm commitments to purchase aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus") as presented in the table below:
Contractual Aircraft Deliveries (b)Expected Aircraft Deliveries (c)

(a) United also has options and purchase rights for additional aircraft.
(b) Contractual aircraft deliveries reflect an agreement United entered into with Airbus on July 16, 2024 to adjust delivery schedules for the A321neo ("Airbus Agreement").
(c) Expected aircraft deliveries reflect adjustments to contractual delivery schedules as communicated by Boeing and Airbus or estimated by United. However, aircraft deliveries are subject to a number of variables, as further described in Part I, Item 1A. Risk Factors of the 2023 Form 10-K, and we cannot guarantee delivery of any particular aircraft at any specific time notwithstanding firm purchase commitments.
19
The aircraft listed in the table above are scheduled for delivery through 2033. The amount and timing of the Company's future capital commitments could change to the extent that: (i) the Company and the aircraft manufacturers, with whom the Company has existing orders for new aircraft, agree to modify the contracts governing those orders; (ii) rights are exercised pursuant to the relevant agreements to cancel deliveries or modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders.
On April 14, 2024, the Company entered into confidential arrangements with Boeing with respect to compensation for financial damages incurred in the first quarter of 2024 due to the Federal Aviation Administration grounding of the Boeing 737 MAX 9 aircraft, and a confidential agreement to accommodate certification delays for the Boeing 737 MAX 10 aircraft. The compensation provided by Boeing for the grounding damages and in connection with rescheduling deliveries was in the form of credit memos for use on future purchases from Boeing. The Company is accounting for these arrangements as a reduction to the cost basis of the previously-delivered Boeing 737 MAX 9 aircraft and future deliveries of the Boeing 737 MAX 9 and Boeing 737 MAX 10 aircraft, which will reduce future depreciation expense associated with these aircraft.
The table below summarizes United's firm commitments as of June 30, 2024, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments communicated by Boeing and Airbus or estimated by United but reflecting the Airbus Agreement and the April 14, 2024 arrangements between United and Boeing.

In the second quarter of 2024, the Company signed letters of intent to enter into future leasing arrangements with major aircraft leasing companies for 40 Airbus A321neo aircraft with expected deliveries in 2026 and 2027. In July 2024, the Company entered into definitive agreements to lease 35 of the 40 Airbus A321neo aircraft, which will commence between 2026 and 2027. As of the filing date of this report, we have leases of approximately $3.7 billion for several mainline aircraft, regional aircraft under CPAs, airport facility and office space leases, none of which had commenced as of such date. These leases will commence between 2024 and 2038 with lease terms of up to 12 years.
Regional CPAs. During the six months ended June 30, 2024, United amended several of its CPAs with certain of its regional carriers to increase the contractually agreed fees (carrier costs) paid to those carriers and to modify the terms for certain aircraft. Our future commitments under our CPAs are dependent on numerous variables, and are, therefore, difficult to predict. The most important of these variables is the number of scheduled block hours. Although we are not required to purchase a minimum number of block hours under certain of our CPAs, we have set forth below estimates of our future payments under the CPAs based on our assumptions. The actual amounts we pay to our regional operators under CPAs could differ materially from these estimates. United's estimates of its future payments under all of the CPAs do not include the portion of the underlying obligation for any aircraft leased to a regional carrier, or deemed to be leased from other regional carriers, and facility rent. For purposes of calculating these estimates, we have assumed (1) the number of block hours flown is based on our anticipated level of flight activity or at any contractual minimum utilization levels if applicable, whichever is higher, (2) that we will reduce the fleet as rapidly as contractually allowed under each CPA, (3) that aircraft utilization, stage length and load factors will remain constant, (4) that each carrier's operational performance will remain at recent historic levels and (5) an annual projected inflation rate. Based on these assumptions as of June 30, 2024, our estimated future payments through the end of the terms of our CPAs are presented in the table below:

Guarantees. As of June 30, 2024, United is the guarantor of approximately $1.9 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with these obligations are accounted for as operating leases recognized on the Company's consolidated balance sheet with the associated expense recorded on a straight-line basis over the expected lease term. All of these bonds are due between 2024 and 2041.
As of June 30, 2024, United is the guarantor of $70 million of aircraft mortgage debt issued by one of United's regional carriers. The aircraft mortgage debt is subject to similar increased cost provisions as described below for the Company's debt, and the Company would potentially be responsible for those costs under the guarantees.
Increased Cost Provisions. In United's financing transactions that include loans in which United is the borrower, United typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans with respect to which the interest rate is based on the Secured Overnight Financing Rate ("SOFR"), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject, in most cases, to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2024, the Company had $10.3 billion of floating rate debt with remaining terms of up to approximately 12 years that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to approximately 12 years and an aggregate balance of $7.2 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.
Labor. As of June 30, 2024, the Company had approximately 106,000 employees, of whom approximately 82% were represented by various U.S. labor organizations.
On February 23, 2024, United's International Association of Machinists and Aerospace Workers ("IAM") represented security guards in California and central load planners ratified new collective bargaining agreements. The ratified agreements are effective through 2025.
On February 28, 2024, United and the International Brotherhood of Teamsters (IBT) reached a tentative agreement for an extension to their labor contract, which covers United's technicians and related employees. On April 17, 2024, the United technicians declined the proposed four-year contract extension and will continue to work under their current agreement, which becomes amendable in December 2024.
NOTE 8 — DEBT
On February 15, 2024, the Company entered into an Amended and Restated Revolving Credit and Guaranty Agreement (the "Revolving Credit Facility") increasing the borrowing capacity by $1.115 billion, which may be drawn upon until February 15, 2029, in the case of any Revolving Loans (as defined in the Revolving Credit Facility) made by the Extending Lenders (as defined in the Revolving Credit Facility), and April 21, 2025, in the case of any Revolving Loans made by the 2024 Non-Extending Lenders (as defined in the Revolving Credit Facility). The revolving loan commitments of the Extending Lenders equal $2.7 billion and the revolving loan commitments of the 2024 Non-Extending Lenders equal $165 million. The Revolving Loans, if any, bear interest at a variable rate equal to Term SOFR (as defined in the Revolving Credit Facility), generally subject to a floor, plus a credit adjustment spread described in the Revolving Credit Facility, or, at United's election, another rate based on certain market interest rates, also generally subject to a floor, in each case plus a variable margin ranging from 3.00% to 3.50%, in the case of Term SOFR loans, and 2.00% to 2.50%, in the case of loans at other market rates. On April 16, 2024, the Company increased the revolving loan commitments of the Extending Lenders by $100 million. The revolving loan commitments of the Extending Lenders now equal $2.8 billion and the revolving loan commitments of the 2024 Non-Extending Lenders remain $165 million. As of June 30, 2024, we had $2.965 billion undrawn and available under the Revolving Credit Facility.
21
On February 22, 2024, the Company also entered into Amendment No. 2 to Term Loan Credit and Guaranty Agreement (as amended, the "Term Loan Facility" and, together with the Revolving Credit Facility, the "Loan Facilities") and (i) used available cash in an amount equal to $1.37 billion to partially prepay the term loans under the 2021 term loans and (ii) borrowed the entire term loan commitment available under the Term Loan Facility in an amount equal to $2.5 billion and used the proceeds of such terms loans (the "Term Loans") to prepay in full the remaining outstanding principal balance under the existing term loan facility. The Term Loans bear interest at a variable rate equal to Term SOFR (subject to a floor of 0.0%); or, at United's election, another rate based on certain market interest rates (subject to a floor of 1.0%), in each case plus a margin of 2.75%, in the case of Term SOFR loans, and 1.75%, in the case of loans at other market rates. The remaining balance of the Term Loans will mature and be due and payable on February 22, 2031.
The table below presents the Company's contractual principal payments (not including $249 million of unamortized debt discount, premiums and debt issuance costs) as of June 30, 2024 under then-outstanding long-term debt agreements (in millions):

During the six months ended June 30, 2024, United borrowed $0.9 billion aggregate principal amount from financial institutions to finance the purchase of aircraft. The notes evidencing these borrowings, which are secured by the related aircraft, mature between 2034 and 2036 and bear interest at variable rates equal to Term SOFR plus a margin of up to 2.00%.
Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of June 30, 2024, UAL and United were in compliance with their respective debt covenants.
On July 2, 2024, the Company voluntarily prepaid in full the outstanding principal balance of the term loan facility of the MileagePlus Financing, which was $1.8 billion as of June 30, 2024, in addition to all accrued and unpaid interest and fees under the term loan facility and terminated all commitments thereunder.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
This Management's Discussion and Analysis of Financial Condition and Results of Operations is provided as a supplement to and should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q to enhance the understanding of our results of operations, financial condition and cash flows.
EXECUTIVE SUMMARY
Overview
United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United").
This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.
Our shared purpose is "Connecting People. Uniting the World." We have the most comprehensive route network among North American carriers, including U.S. mainland hubs in Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco and Washington, D.C. The Company transports people and cargo through its mainline operations, which utilize jet aircraft with at least 126 seats, and regional operations, which utilize smaller aircraft that are operated under contract by United's regional carriers. The Company serves virtually every major market around the world, either directly or through participation in Star Alliance®, the world's largest airline alliance.
Our current expectations described below are forward-looking statements and our actual results and timing may vary materially based on various factors that include, but are not limited to, those discussed below under "Economic and Market Factors", "Governmental Actions" and "Forward-Looking Information" and in Part I, Item 1A. Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the "2023 Form 10-K"). The results presented in this report are not necessarily indicative of future operating results.
Economic and Market Factors
The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. We, like other companies in our industry, have been subject to these and other industry-specific competitive dynamics. In addition, our operations, supply chain, partners and suppliers have been subject to various global macroeconomic factors. We expect to continue to remain vulnerable to a number of industry-specific and global macroeconomic factors that may cause our actual results of operations to differ from our historical results of operations or current expectations. The economic and market factors and trends that we currently believe are or will be most impactful to our results of operations and financial condition include the following: the execution risks associated with our United Next plan, especially relating to the growth in the scale of our operations as a result of the plan; the impact on the Company of significant operational challenges by third parties on which we rely; rising inflationary pressures; labor market and supply chain constraints and related costs affecting us and our partners; volatile fuel prices; aircraft delivery delays; increasing maintenance expenses; high interest rates; and changes in general economic conditions in the markets in which the Company operates, including an economic downturn leading to a decrease in demand for air travel or fluctuations in foreign currency exchange rates that may impact international travel demand. We continue to monitor the potential favorable or unfavorable impacts of these and other factors on our business, operations, financial condition, future results of operations, liquidity and financial flexibility, which are dependent on future developments, including as a result of those factors discussed in Part I, Item 1A. Risk Factors, of the 2023 Form 10-K. Our future results of operations may be subject to volatility and our growth plans may be delayed, particularly in the short term, due to the impact of the above factors and trends.
Governmental Actions
We operate in complex, highly regulated environments in the U.S., the European Union, the United Kingdom and other regions around the world. Compliance with laws, regulations, administrative practices and other restrictions or legal requirements in the countries in which we do business is onerous and expensive. In addition, changes to existing legal requirements or the

implementation of new legal requirements and any failure to comply with such legal requirements could negatively impact our business, operations, financial condition, future results of operations, liquidity and financial flexibility by increasing the Company's costs, limiting the Company's ability to offer a product, service or feature to customers, impacting customer demand for the Company's products and services and requiring changes to the Company's supply chain and its business. Legal requirements that we currently believe are or will be most impactful to our results of operations and financial condition include the following: increased oversight by the Federal Aviation Administration ("FAA") of the Company’s operations in connection with its evaluation of the Company; the closure of our flying airspace and termination of other operations due to regional conflicts, including the suspension of our overflying in Russian airspace as a result of the Russia-Ukraine military conflict and interruptions of our flying to Tel Aviv as a result of the Israeli-Hamas military conflict, as well as any escalation of the broader economic consequences of these conflicts beyond their current scope; delays in aircraft certification (especially relating to the 737 MAX 10 aircraft); increased FAA oversight of the aircraft production process; and any legal requirement that would result in a reshaping of the benefits that we provide to our consumers through the co-branded credit cards issued by our partner. Changes in existing applicable legal requirements or new applicable legal requirements as well as the related interpretations and enforcement practices regarding them, create uncertainty about how such laws and regulations will be understood and applied. As a result, the impact of changing and new legal requirements generally cannot be reasonably predicted and those requirements may ultimately require extensive system and operational changes, be difficult to implement, increase our operating costs and require significant capital expenditures.
RESULTS OF OPERATIONS
The following discussion provides an analysis of our results of operations and reasons for material changes therein for the three and six months ended June 30, 2024, as compared to the corresponding period in 2023.
Second Quarter 2024 Compared to Second Quarter 2023

(a) NM - Greater than 100% change or otherwise not meaningful.
Salaries and related costs increased $388 million, or 10.5%, in the second quarter of 2024 as compared to the year-ago period, primarily due to annual wage rate increases across certain employee groups and a 6.2% increase in headcount largely due to increased flight activity.
Aircraft fuel expense increased by $313 million, or 11.1%, in the second quarter of 2024 as compared to the year-ago period, due to increased consumption from higher flight activity and a higher average price per gallon of fuel. The table below presents the significant changes in aircraft fuel cost per gallon in the three months ended June 30 (in millions, except percentage change and per gallon data):

Landing fees and other rent increased $101 million, or 13.2%, in the second quarter of 2024 as compared to the year-ago period, primarily due to rate increases at various airports, terminal expansions and other increases in the number of airport gates and higher landed weight volume due to increased flight activity.
Depreciation expense increased $50 million, or 7.5%, in the second quarter of 2024 as compared to the year-ago period, primarily due to the induction of new aircraft and related spare parts, as well as certain aircraft improvements.
Distribution expenses increased $139 million, or 28.5%, in the second quarter of 2024 as compared to the year-ago period, primarily due to higher credit card fees, agency commissions and global distribution fees driven by the overall increase in passenger revenue and $64 million of commissions that were recorded as contra-revenue in 2023.

Interest expense decreased $66 million, or 13.4%, in the second quarter of 2024 as compared to the year-ago period, primarily due to declining debt balances and lower interest rates on refinanced debt.
Interest income decreased $26 million, or 12.0%, in the second quarter of 2024 as compared to the year-ago period, primarily due to lower short-term investments in U.S. government and agency notes, which was partially offset by higher interest rates.
Unrealized losses on investments, net, was $33 million in the second quarter of 2024 as compared to $84 million in unrealized gains in the year-ago period, primarily due to the change in the market value of the Company's investments in equity securities.

LIQUIDITY AND CAPITAL RESOURCES
Current Liquidity
As of June 30, 2024, the Company had $15.2 billion in unrestricted cash, cash equivalents and short-term investments, as compared to $14.4 billion at December 31, 2023. We believe that our existing cash, cash equivalents and short-term investments, together with cash generated from operations, will be sufficient to satisfy our anticipated liquidity needs for the next twelve months, and we expect to meet our long-term liquidity needs with our anticipated access to the capital markets and projected cash from operations. We regularly assess our anticipated working capital needs, debt and leverage levels, debt maturities, capital expenditure requirements (including in connection with our capital commitments for our firm order aircraft) and future investments or acquisitions in order to maximize shareholder return, efficiently finance our ongoing operations and maintain flexibility for future strategic transactions. We also regularly evaluate our liquidity and capital structure to ensure financial risks, liquidity access and cost of capital are efficiently managed.
On April 16, 2024, the Company increased its revolving credit facility (the "Revolving Credit Facility") loan commitments by $100 million for a total amount of $2.965 billion as of June 30, 2024, of which $2.8 billion expires February 15, 2029 and $165 million expires April 21, 2025. The Revolving Credit Facility is secured by certain route authorities and airport slots and gates. No borrowings were outstanding under the Revolving Credit Facility as of June 30, 2024.
31
We have a significant amount of fixed obligations, including debt, leases of aircraft, airport and other facilities, and pension funding obligations. As of June 30, 2024, the Company had approximately $34.3 billion of debt, finance lease, operating lease and other financial liabilities, including $5.5 billion that will become due in the next 12 months. In addition, we have substantial noncancelable commitments for capital expenditures, including the acquisition of certain new aircraft and related spare engines. Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of June 30, 2024, UAL and United were in compliance with their respective debt covenants. As of June 30, 2024, a substantial portion of the Company's assets, principally aircraft and certain related assets, its loyalty program, certain route authorities and airport slots and gates, was pledged under various loan and other agreements. See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information on aircraft financing and other debt instruments.
On July 2, 2024, the Company voluntarily prepaid in full the outstanding principal balance of the term loan facility of our MileagePlus term loan, which was $1.8 billion as of June 30, 2024, in addition to all accrued and unpaid interest and fees under the term loan facility and terminated all commitments thereunder.
The Company has backstop financing commitments available from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. See Note 7 to the financial statements included in Part I, Item 1 of this report for additional information on commitments.
As of June 30, 2024, United had firm commitments to purchase aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus") as presented in the table below:

(a) United also has options and purchase rights for additional aircraft.
(b) Contractual aircraft deliveries reflect an agreement United entered into with Airbus on July 16, 2024 to adjust delivery schedules for the A321neo ("Airbus Agreement").
(c) Expected aircraft deliveries reflect adjustments to contractual delivery schedules as communicated by Boeing and Airbus or estimated by United. However, aircraft deliveries are subject to a number of variables, as further described in Part I, Item 1A. Risk Factors of the 2023 Form 10-K, and we cannot guarantee delivery of any particular aircraft at any specific time notwithstanding firm purchase commitments.
The aircraft listed in the table above are scheduled for delivery through 2033. The amount and timing of the Company's future capital commitments could change to the extent that: (i) the Company and the aircraft manufacturers, with whom the Company has existing orders for new aircraft, agree to modify the contracts governing those orders; (ii) rights are exercised pursuant to the relevant agreements to cancel deliveries or modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders.
On April 14, 2024, the Company entered into confidential arrangements with Boeing with respect to compensation for financial damages incurred in the first quarter of 2024 due to the FAA grounding of the Boeing 737 MAX 9 aircraft, and a confidential agreement to accommodate certification delays for the Boeing 737 MAX 10 aircraft. The compensation provided by Boeing for the grounding damages and in connection with rescheduling deliveries was in the form of credit memos for use on future purchases from Boeing. The Company is accounting for these arrangements as a reduction to the cost basis of the previously-delivered Boeing 737 MAX 9 aircraft and future deliveries of the Boeing 737 MAX 9 and Boeing 737 MAX 10 aircraft, which will reduce future depreciation expense associated with these aircraft.
The table below summarizes United's firm commitments as of June 30, 2024, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments communicated by Boeing and Airbus or estimated by United but reflecting the Airbus Agreement and the April 14, 2024 arrangements between United and Boeing.

In the second quarter of 2024, the Company signed letters of intent to enter into future leasing arrangements with major aircraft leasing companies for 40 Airbus A321neo aircraft with expected deliveries in 2026 and 2027. In July 2024, the Company entered into definitive agreements to lease 35 of the 40 Airbus A321neo aircraft, which will commence between 2026 and 2027. As of the filing date of this report, we have leases of approximately $3.7 billion for several mainline aircraft, regional aircraft under CPAs, airport facility and office space leases, none of which had commenced as of such date. These leases will commence between 2024 and 2038 with lease terms of up to 12 years.
Sources and Uses of Cash
The following table summarizes our cash flows for the six months ended June 30 (in millions):
20242023Increase (Decrease)
Total cash provided by (used in):
Operating activities$5,723 $6,941 $(1,218)
Investing activities1,575 (3,427)(5,002)
Financing activities(2,518)(1,054)1,464 
Net increase in cash, cash equivalents and restricted cash$4,780 $2,460 $2,320 
Operating Activities. Cash flows provided by operations decreased $1.2 billion in the first six months of 2024 as compared to the year-ago period, primarily due to changes in various working capital items, including higher payments for employee wages and incentives in 2024 as compared to 2023.
Investing Activities. Cash flows used in investing activities decreased $5.0 billion in the first six months of 2024 as compared to the year-ago period, primarily due to a decrease in the purchase of short-term and other investments.
Financing Activities. Significant financing events in the six months ended June 30, 2024 were as follows:
Debt, Finance Lease and Other Financing Liability Principal Payments. During the six months ended June 30, 2024, the Company made payments for debt, finance leases, and other financing liabilities of $6.2 billion, including the $3.9 billion prepayment of its 2021 term loan.
Debt and Other Financing Liabilities Issuances. The Company borrowed the entire term loan commitment available under the new term loan facility in an amount equal to $2.5 billion. Also, the Company borrowed $895 million for aircraft financings.
See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information on these financing activities.
Credit Ratings. As of the filing date of this report, UAL and United had the following corporate credit ratings:
S&PMoody'sFitch
UALBB-Ba2BB-
UnitedBB-*BB-
*The credit agency does not issue corporate credit ratings for subsidiary entities.

These credit ratings are below investment grade levels; however, the Company has been able to secure financing with investment grade credit ratings for certain enhanced equipment trust certificates, term loans and secured bond financings.
33
Downgrades from these rating levels, among other things, could restrict the availability, or increase the cost, of future financing for the Company as well as affect the fair market value of existing debt. A rating reflects only the view of a rating agency and is not a recommendation to buy, sell or hold securities. Ratings can be revised upward or downward at any time by a rating agency if such rating agency decides that circumstances warrant such a change.
Commitments, Contingencies and Liquidity Matters. As described in the 2023 Form 10-K, the Company's liquidity may be adversely impacted by a variety of factors, including, but not limited to, pension funding obligations, reserve requirements associated with credit card processing agreements, guarantees, commitments and contingencies.
See the 2023 Form 10-K and Notes 6, 7 and 8 to the financial statements contained in Part I, Item 1 of this report for additional information.
CRITICAL ACCOUNTING POLICIES
See "Critical Accounting Policies" in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in the 2023 Form 10-K.
FORWARD-LOOKING INFORMATION
This report contains certain "forward-looking statements," within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including in Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and elsewhere, relating to, among other things, goals, plans and projections regarding the Company's financial position, results of operations, market position, capacity, fleet plan strategy, product development, ESG-related strategy initiatives and business strategy. Such forward-looking statements are based on historical performance and current expectations, estimates, forecasts and projections about the Company's future financial results, goals, plans, commitments, strategies and objectives and involve inherent risks, assumptions and uncertainties, known or unknown, including internal or external factors that could delay, divert or change any of them, that are difficult to predict, may be beyond the Company's control and could cause the Company's future financial results, goals, plans, commitments, strategies and objectives to differ materially from those expressed in, or implied by, the statements. Words such as "should," "could," "would," "will," "may," "expects," "plans," "intends," "anticipates," "indicates," "remains," "believes," "estimates," "projects," "forecast," "guidance," "outlook," "goals," "targets," "pledge," "confident," "optimistic," "dedicated," "positioned," "on track" and other words and terms of similar meaning and expression are intended to identify forward-looking statements, although not all forward-looking statements contain such terms. All statements, other than those that relate solely to historical facts, are forward-looking statements.
Additionally, forward-looking statements include conditional statements and statements that identify uncertainties or trends, discuss the possible future effects of known trends or uncertainties, or that indicate that the future effects of known trends or uncertainties cannot be predicted, guaranteed or assured. All forward-looking statements in this report are based upon information available to us on the date of this report. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, except as required by applicable law or regulation.
Our actual results could differ materially from these forward-looking statements due to numerous factors including, without limitation, the following: execution risks associated with our strategic operating plan; changes in our fleet and network strategy or other factors outside our control resulting in less economic aircraft orders, costs related to modification or termination of aircraft orders or entry into aircraft orders on less favorable terms, as well as any inability to accept or integrate new aircraft into our fleet as planned, including as a result of any mandatory groundings of aircraft; any failure to effectively manage, and receive anticipated benefits and returns from, acquisitions, divestitures, investments, joint ventures and other portfolio actions, or related exposures to unknown liabilities or other issues or underperformance as compared to our expectations; adverse publicity, harm to our brand, reduced travel demand, potential tort liability and operational restrictions as a result of an accident, catastrophe or incident involving us, our regional carriers, our codeshare partners or another airline; the highly competitive nature of the global airline industry and susceptibility of the industry to price discounting and changes in capacity, including as a result of alliances, joint business arrangements or other consolidations; our reliance on a limited number of suppliers to source a majority of our aircraft, engines and certain parts, and the impact of any failure to obtain timely deliveries, additional equipment or support from any of these suppliers; disruptions to our regional network and United Express flights provided by third-party regional carriers; unfavorable economic and political conditions in the United States and globally; reliance on third-party service providers and the impact of any significant failure of these parties to perform as expected, or interruptions in our relationships with these providers or their provision of services; extended interruptions or disruptions in service at major airports where we operate and space, facility and infrastructure constraints at our hubs or other airports; geopolitical conflict, terrorist attacks or security events (including the suspension of our overflying in Russian airspace as a result of the Russia-Ukraine military conflict and interruptions of our flying to Tel Aviv as a result of the Israeli-Hamas military conflict, as well as
34
any escalation of the broader economic consequences of these conflicts beyond their current scope); any damage to our reputation or brand image; our reliance on technology and automated systems to operate our business and the impact of any significant failure or disruption of, or failure to effectively integrate and implement, these technologies or systems; increasing privacy, data security and cybersecurity obligations or a significant data breach; increased use of social media platforms by us, our employees and others; the impacts of union disputes, employee strikes or slowdowns, and other labor-related disruptions or regulatory compliance costs on our operations or financial performance; any failure to attract, train or retain skilled personnel, including our senior management team or other key employees; the monetary and operational costs of compliance with extensive government regulation of the airline industry; current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or agreement relating to these actions; costs, liabilities and risks associated with environmental regulation and climate change, and any failure to achieve or demonstrate progress towards our climate goals; high and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel; the impacts of our significant amount of financial leverage from fixed obligations and the impacts of insufficient liquidity on our financial condition and business; failure to comply with financial and other covenants governing our debt, including our MileagePlus® financing agreements; limitations on our ability to use our net operating loss carryforwards and certain other tax attributes to offset future taxable income for U.S. federal income tax purposes; our failure to realize the full value of our intangible assets or our long-lived assets, causing us to record impairments; fluctuations in the price of our common stock; the impacts of seasonality and other factors associated with the airline industry; increases in insurance costs or inadequate insurance coverage; and other risks and uncertainties set forth under Part I, Item 1A. Risk Factors, of the 2023 Form 10-K, and under "Economic and Market Factors" and "Governmental Actions" in Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report, as well as other risks and uncertainties set forth from time to time in the reports we file with the SEC.
The foregoing list sets forth many, but not all, of the factors that could impact our ability to achieve results described in any forward-looking statements. Investors should understand that it is not possible to predict or identify all such factors and should not consider this list to be a complete statement of all potential risks and uncertainties. It is routine for our internal projections and expectations to change as the year or each quarter in the year progresses, and therefore it should be clearly understood that the internal projections, beliefs and assumptions upon which we base our expectations may change. For instance, we regularly monitor future demand and booking trends and adjust capacity, as needed. As such, our actual flown capacity may differ materially from currently published flight schedules or current estimations.

COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.
The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations for interim periods presented. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the "2023 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand and were better than its first and fourth quarter financial results.

Advance Ticket Sales. The Company defers amounts related to future travel in its Advance ticket sales liability account. All tickets sold at any given point in time have travel dates through the next 12 months. The Company estimates the value of Advance ticket sales that will expire unused ("breakage") and recognizes revenue and any changes in estimates in proportion to the usage of the related tickets. To determine breakage, the Company uses its historical experience with expired tickets and certificates and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns.
In the six months ended June 30, 2024 and 2023, the Company recognized approximately $5.0 billion and $4.6 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods.
Ancillary Fees. The Company charges fees, separately from ticket sales, for certain ancillary services that are directly related to passengers' travel. This includes fees for baggage, premium seats, inflight amenities and other ticket-related fees. These ancillary fees are part of the travel performance obligation and, as such, are recognized as passenger revenue when the travel occurs. The Company recorded $1.2 billion and $2.2 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2024, respectively. The Company recorded $1.0 billion and $1.9 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2023, respectively.

In the three and six months ended June 30, 2024, the Company recognized, in Other operating revenue, $0.7 billion and $1.5 billion, respectively, related to the marketing, advertising, non-travel miles redeemed (net of related costs) and other travel-related benefits of the mileage revenue associated with our various partner agreements including, but not limited to, our JPMorgan Chase Bank, N.A. MileagePlus co-brand agreement. The Company recognized $0.7 billion and $1.3 billion, respectively, in the three and six months ended June 30, 2023, related to those agreements. The portion related to the MileagePlus miles awarded of the total amounts received from our various partner agreements is deferred and presented in the table above as an increase to the Frequent flyer deferred revenue. We determine the current portion of that account based on our estimate of expected redemptions in the next 12 months.

These warrants were originally issued to the U.S. Treasury Department ("Treasury") pursuant to the payroll support program, including extensions, and the loan program established under the Coronavirus Aid, Relief, and Economic Security Act. Treasury sold these warrants at an auction held on June 6, 2024. All warrants were outstanding as of June 30, 2024.

The Fund is an investment vehicle designed to invest in start-ups developing technologies focused on decarbonizing aviation and its associated energy supply chains, including through research and production, and technologies associated with sustainable aviation fuel (SAF).
Other Investments. As of June 30, 2024, United has equity investments in Abra Group Limited, a multinational airline holding company, JetSuiteX, Inc., an independent air carrier doing business as JSX, as well as a number of companies with emerging technologies and sustainable solutions. None of these investments have readily determinable fair values. We account for these investments at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. As of June 30, 2024, the carrying value of these investments was $423 million.
Notes Receivable. As of June 30, 2024, the Company has $86 million of notes receivable, net of allowance for credit losses, the majority of which is from certain of its regional carriers.

(a) United also has options and purchase rights for additional aircraft.
(b) Contractual aircraft deliveries reflect an agreement United entered into with Airbus on July 16, 2024 to adjust delivery schedules for the A321neo ("Airbus Agreement").
(c) Expected aircraft deliveries reflect adjustments to contractual delivery schedules as communicated by Boeing and Airbus or estimated by United. However, aircraft deliveries are subject to a number of variables, as further described in Part I, Item 1A. Risk Factors of the 2023 Form 10-K, and we cannot guarantee delivery of any particular aircraft at any specific time notwithstanding firm purchase commitments.
The aircraft listed in the table above are scheduled for delivery through 2033. The amount and timing of the Company's future capital commitments could change to the extent that: (i) the Company and the aircraft manufacturers, with whom the Company has existing orders for new aircraft, agree to modify the contracts governing those orders; (ii) rights are exercised pursuant to the relevant agreements to cancel deliveries or modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders.
On April 14, 2024, the Company entered into confidential arrangements with Boeing with respect to compensation for financial damages incurred in the first quarter of 2024 due to the Federal Aviation Administration grounding of the Boeing 737 MAX 9 aircraft, and a confidential agreement to accommodate certification delays for the Boeing 737 MAX 10 aircraft. The compensation provided by Boeing for the grounding damages and in connection with rescheduling deliveries was in the form of credit memos for use on future purchases from Boeing. The Company is accounting for these arrangements as a reduction to the cost basis of the previously-delivered Boeing 737 MAX 9 aircraft and future deliveries of the Boeing 737 MAX 9 and Boeing 737 MAX 10 aircraft, which will reduce future depreciation expense associated with these aircraft.
The table below summarizes United's firm commitments as of June 30, 2024, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments communicated by Boeing and Airbus or estimated by United but reflecting the Airbus Agreement and the April 14, 2024 arrangements between United and Boeing.

In the second quarter of 2024, the Company signed letters of intent to enter into future leasing arrangements with major aircraft leasing companies for 40 Airbus A321neo aircraft with expected deliveries in 2026 and 2027. In July 2024, the Company entered into definitive agreements to lease 35 of the 40 Airbus A321neo aircraft, which will commence between 2026 and 2027. As of the filing date of this report, we have leases of approximately $3.7 billion for several mainline aircraft, regional aircraft under CPAs, airport facility and office space leases, none of which had commenced as of such date. These leases will commence between 2024 and 2038 with lease terms of up to 12 years.
Regional CPAs. During the six months ended June 30, 2024, United amended several of its CPAs with certain of its regional carriers to increase the contractually agreed fees (carrier costs) paid to those carriers and to modify the terms for certain aircraft. Our future commitments under our CPAs are dependent on numerous variables, and are, therefore, difficult to predict. The most important of these variables is the number of scheduled block hours. Although we are not required to purchase a minimum number of block hours under certain of our CPAs, we have set forth below estimates of our future payments under the CPAs based on our assumptions. The actual amounts we pay to our regional operators under CPAs could differ materially from these estimates. United's estimates of its future payments under all of the CPAs do not include the portion of the underlying obligation for any aircraft leased to a regional carrier, or deemed to be leased from other regional carriers, and facility rent. For purposes of calculating these estimates, we have assumed (1) the number of block hours flown is based on our anticipated level of flight activity or at any contractual minimum utilization levels if applicable, whichever is higher, (2) that we will reduce the fleet as rapidly as contractually allowed under each CPA, (3) that aircraft utilization, stage length and load factors will remain constant, (4) that each carrier's operational performance will remain at recent historic levels and (5) an annual projected inflation rate. Based on these assumptions as of June 30, 2024, our estimated future payments through the end of the terms of our CPAs are presented in the table below:

Guarantees. As of June 30, 2024, United is the guarantor of approximately $1.9 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with these obligations are accounted for as operating leases recognized on the Company's consolidated balance sheet with the associated expense recorded on a straight-line basis over the expected lease term. All of these bonds are due between 2024 and 2041.
As of June 30, 2024, United is the guarantor of $70 million of aircraft mortgage debt issued by one of United's regional carriers. The aircraft mortgage debt is subject to similar increased cost provisions as described below for the Company's debt, and the Company would potentially be responsible for those costs under the guarantees.
Increased Cost Provisions. In United's financing transactions that include loans in which United is the borrower, United typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans with respect to which the interest rate is based on the Secured Overnight Financing Rate ("SOFR"), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject, in most cases, to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2024, the Company had $10.3 billion of floating rate debt with remaining terms of up to approximately 12 years that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to approximately 12 years and an aggregate balance of $7.2 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.
Labor. As of June 30, 2024, the Company had approximately 106,000 employees, of whom approximately 82% were represented by various U.S. labor organizations.
On February 23, 2024, United's International Association of Machinists and Aerospace Workers ("IAM") represented security guards in California and central load planners ratified new collective bargaining agreements. The ratified agreements are effective through 2025.
On February 28, 2024, United and the International Brotherhood of Teamsters (IBT) reached a tentative agreement for an extension to their labor contract, which covers United's technicians and related employees. On April 17, 2024, the United technicians declined the proposed four-year contract extension and will continue to work under their current agreement, which becomes amendable in December 2024.

The revolving loan commitments of the Extending Lenders equal $2.7 billion and the revolving loan commitments of the 2024 Non-Extending Lenders equal $165 million. The Revolving Loans, if any, bear interest at a variable rate equal to Term SOFR (as defined in the Revolving Credit Facility), generally subject to a floor, plus a credit adjustment spread described in the Revolving Credit Facility, or, at United's election, another rate based on certain market interest rates, also generally subject to a floor, in each case plus a variable margin ranging from 3.00% to 3.50%, in the case of Term SOFR loans, and 2.00% to 2.50%, in the case of loans at other market rates. On April 16, 2024, the Company increased the revolving loan commitments of the Extending Lenders by $100 million. The revolving loan commitments of the Extending Lenders now equal $2.8 billion and the revolving loan commitments of the 2024 Non-Extending Lenders remain $165 million. As of June 30, 2024, we had $2.965 billion undrawn and available under the Revolving Credit Facility.
On February 22, 2024, the Company also entered into Amendment No. 2 to Term Loan Credit and Guaranty Agreement (as amended, the "Term Loan Facility" and, together with the Revolving Credit Facility, the "Loan Facilities") and (i) used available cash in an amount equal to $1.37 billion to partially prepay the term loans under the 2021 term loans and (ii) borrowed the entire term loan commitment available under the Term Loan Facility in an amount equal to $2.5 billion and used the proceeds of such terms loans (the "Term Loans") to prepay in full the remaining outstanding principal balance under the existing term loan facility. The Term Loans bear interest at a variable rate equal to Term SOFR (subject to a floor of 0.0%); or, at United's election, another rate based on certain market interest rates (subject to a floor of 1.0%), in each case plus a margin of 2.75%, in the case of Term SOFR loans, and 1.75%, in the case of loans at other market rates. The remaining balance of the Term Loans will mature and be due and payable on February 22, 2031.

The notes evidencing these borrowings, which are secured by the related aircraft, mature between 2034 and 2036 and bear interest at variable rates equal to Term SOFR plus a margin of up to 2.00%.
Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of June 30, 2024, UAL and United were in compliance with their respective debt covenants.
On July 2, 2024, the Company voluntarily prepaid in full the outstanding principal balance of the term loan facility of the MileagePlus Financing, which was $1.8 billion as of June 30, 2024, in addition to all accrued and unpaid interest and fees under the term loan facility and terminated all commitments thereunder
