Segment Reporting [Abstract]  
OPERATING SEGMENT INFORMATION OPERATING SEGMENT INFORMATION
Alaska Air Group has three operating airlines – Alaska, Hawaiian, 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.

Air Group's Chief Operating Decision Maker (CODM) is its President and CEO. In the third quarter of 2024, the CODM began to review financial results for Hawaiian to assess performance and make resource allocation decisions for Air Group. As a result, the Company determined Hawaiian was an operating and reportable segment.

Air Group's network and schedules are centrally managed for all its operating airlines and CPA flying. Managing the business in an integrated manner enables the Company to leverage its comprehensive network, route scheduling system, and fleet as a single business. The CODM makes resource allocation decisions to deliver optimized consolidated financial results, regardless of the profitability of an individual segment. Air Group intends to combine Alaska and Hawaiian under a single operating certificate in the near term. At that time, management anticipates the discrete information provided to the CODM will similarly be combined. Management is considering other changes to internal reporting that may impact the discrete information provided to the CODM to better align with the way the business is managed. These changes may have an impact on the Company's reportable segments once finalized.

The CODM reviews financial performance information as part of three reportable operating segments which are described above:
•Alaska Airlines - includes scheduled air transportation on Alaska's Boeing aircraft for passengers and cargo.
•Hawaiian Airlines - includes scheduled air transportation on Hawaiian's Boeing and Airbus aircraft for passengers and cargo.
•Regional - includes Horizon's and other third-party carriers’ scheduled air transportation on E175 aircraft for passengers under CPAs. This segment includes the actual revenue and expenses associated with regional flying, as well as an allocation of corporate overhead incurred by Air Group on behalf of the regional operations.

The below tables present segment revenue and expenses for Air Group's reportable segments. Air Group's measure of segment profit or loss is pretax profit, which is used by the CODM to evaluate financial results. Additionally, reconciliations of the pretax profit of all reportable segments to Air Group's consolidated income before income tax are provided.
