Alaska Airlines has launched its much-anticipated joint loyalty program with Hawaiian Airlines, Atmos Rewards. (Note that the Hawaiian Airlines HawaiianMiles program will officially end Oct. 1, and your miles will automatically be transferred at a 1:1 ratio to Atmos Rewards.)

On August 20, both airlines announced the launch of Atmos Rewards. By October 1, 2025, Atmos will replace both Alaska's Mileage Plan and Hawaiian's HawaiianMiles as the united loyalty program, promising new ways to earn points and elite status, along with new credit card perks.

Hawaiian airlines and Alaska airlines are combining their loyalty programs into Atmos Rewards, with HawaiianMiles members set to transition on Oct. 1 while keeping their miles and status.
