Lease Commitments

At March 31, 2014, the Company had lease contracts for 59 aircraft, which have remaining noncancelable lease terms ranging from 2014 to 2021. Of these aircraft, 14 are non-operating (i.e. not in the Company's fleet) and subleased to third-party carriers. The majority of airport and terminal facilities are also leased. Rent expense for aircraft and facility leases was $75 million and $70 million for the three months ended March 31, 2014 and 2013, respectively.

Aircraft Commitments

As of March 31, 2014, the Company is committed to purchasing 65 B737 aircraft (28 B737-900ER aircraft and 37 B737 MAX aircraft), with deliveries in 2014 through 2022. In addition, the Company has options to purchase an additional 62 B737 aircraft and seven Q400 aircraft.

Capacity Purchase Agreements (CPAs)

At March 31, 2014, Alaska had CPAs with three carriers, including the Company's wholly-owned subsidiary, Horizon. Horizon sells 100% of its capacity to Alaska under a CPA, which is eliminated upon consolidation. In addition, Alaska has CPAs with SkyWest Airlines, Inc. (SkyWest) to fly certain routes and Peninsula Airways, Inc. (PenAir) to fly one route in the state of Alaska. Under these agreements, Alaska pays the third-party carriers an amount which is based on a determination of their cost of operating those flights and other factors. The costs paid by Alaska to Horizon are based on similar data and are intended to approximate market rates for those services. Future payments (excluding those due to Horizon) are based on contractually required minimum levels of flying by the third-party carriers, which could differ materially due to variable payments based on actual levels of flying and certain costs associated with operating flights, such as fuel.

Engine Maintenance

The Company has a power-by-the-hour (PBH) maintenance agreement for some of the B737-700 and B737-900 engines. This agreement transfers risk to a third-party service provider and fixes the amount the Company pays per flight hour in exchange for maintenance and repairs under a predefined maintenance program. Future payments are based on minimum flight hours.
