Hawaiian Airlines’ HA Code Is Gone as Alaska’s oneworld Push Hits Passenger Tickets
Hawaiian Airlines has joined oneworld, becoming the alliance’s third U.S. member after Alaska and American. Hawaiian flights now use Alaska’s AS code and run on Alaska’s Sabre reservation system, though the Hawaiian brand remains visible. The change follows Alaska Air Group’s 2024 acquisition of Hawaiian Holdings. Atmos Rewards members now access expanded loyalty benefits across oneworld airlines.
