OPERATING SEGMENT INFORMATION

OPERATING SEGMENT INFORMATION

Alaska Air Group has two operating airlines – Alaska and Horizon. Each is regulated by the U.S. Department of Transportation’s Federal Aviation Administration. Alaska has CPAs for regional capacity with Horizon and SkyWest, under which Alaska receives all passenger revenues.

Under U.S. GAAP, operating segments are defined as components of a business for which there is discrete financial information that is regularly assessed by the Chief Operating Decision Maker (CODM) in making resource allocation decisions. Financial performance for the operating airlines and CPAs is managed and reviewed by the Company's CODM as part of three reportable operating segments:

•Mainline - includes scheduled air transportation on Alaska's Boeing or Airbus jet aircraft for passengers and cargo throughout the U.S., and in parts of Canada, Mexico, Costa Rica, and Belize.

•Regional - includes Horizon's and other third-party carriers’ scheduled air transportation for passengers across a shorter distance network within the U.S. and Canada under a CPA. This segment includes the actual revenues and expenses associated with regional flying, as well as an allocation of corporate overhead incurred by Air Group on behalf of the regional operations.

•Horizon - includes the capacity sold to Alaska under CPA. Expenses include those typically borne by regional airlines such as crew costs, ownership costs and maintenance costs.

The CODM makes resource allocation decisions for these reporting segments based on flight profitability data, aircraft type, route economics and other financial information.

The "Consolidating and Other" column reflects Air Group parent company activity, McGee Air Services, consolidating entries and other immaterial business units of the company. The “Air Group Adjusted” column represents a non-GAAP measure that is used by the Company's CODM to evaluate performance and allocate resources. Adjustments are further explained below in reconciling to consolidated GAAP results.
