Hawaiian Airlines will officially join the oneworld® alliance on April 22, 2026. This marks one of the final milestones in its ongoing integration with Alaska Airlines following the acquisition in September 2024. While Hawaiian is part of Alaska Air Group, the merger has been unfolding in careful phases. In October 2025, the two carriers consolidated under a single operating certificate, yet both brands will continue to exist independently: Hawaiian for all flights to and from Hawaii and Alaska for all other routes.
oneworld® entry aligns with the date the airlines will transition to a unified passenger service system. This will also mark the retirement of Hawaiian’s “HA” code, with all flights moving to Alaska’s “AS” designation behind the scenes. Although customers will still see Hawaiian branding on Hawaii-bound services, the two airlines will function as a single entity.
Hawaiian’s addition to oneworld® further expands the alliance’s global reach and continues a recent trend that has seen Fiji Airways and Oman Air join and Starlux Airlines express interest. oneworld® is experiencing renewed momentum after several years of stagnation.
The integration is further bolstered by the launch of Atmos Rewards, which is the combined loyalty program for Alaska and Hawaiian. Hawaiian flyers already benefit from the program’s participation in oneworld®. When Hawaiian formally joins the alliance, the biggest changes will be felt by customers loyal to other oneworld® carriers as they will be able to earn and redeem miles and enjoy elite benefits on Hawaiian-operated flights more seamlessly.
Anthony’s Take: While some oneworld® airlines already partner with Hawaiian, alliance membership will streamline connections, frequent flyer reciprocity, and global booking functionality. As Alaska and Hawaiian continue to merge their systems and loyalty structures, joining oneworld® represents a key step in solidifying the pair.
