American Airlines will pay a 10.5% yield on its priced its private offering of $450 million for the principal amount of its 10 1/2% three-year senior secured notes.

The bond sale, which was announced on Wednesday, came just two days after American Airlines' parent AMR Corp. (AMR) disclosed its own stock-and-note sale.

The airline company has said the sale of the $450 million of notes will be secured by certain company aircraft, with proceeds to refinance an existing $432 million secured bank term loan facility.

A number of companies have been flooding the markets in recent months, selling equity and/or debt to raise capital with many looking to pay down near-term borrowings. The AMR sale, along with plans by Delta Air Lines Inc. (DAL) for a $2 billion loan and bond refinancing, is another sign the capital markets are opening up even to very risky companies.

AMR's shares were up 3.5% to $8.01 in recent trading amid a broad rally for airline stocks.
