On March 31, 2010, Alaska Airlines, Inc. finalized two separate $100 million variable-rate credit facilities with a syndicate of financial institutions.

Borrowings on one of the $100 million facilities will be secured by aircraft collateral.  The syndicate for this facility is led by Citibank, N.A. as administrative agent and Bank of America, N.A. as syndication agent, and includes Societe Generale.  This facility will expire in March 2013.

Borrowings on the other $100 million facility will be secured by certain accounts receivable, spare engines, spare parts and ground service equipment.  The syndicate for this facility is led by Wells Fargo Capital Finance, LLC, part of Wells Fargo & Company (NYSE:WFC), as agent and US Bank National Association as documentation agent, and includes Bank SinoPac.  This facility will expire in March 2014.

These facilities replace the Company's $185 million credit facility that terminated March 30, 2010.  The Company has no immediate plans to borrow using either of these credit facilities.
