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.)

The new Atmos Rewards Summit card boasts a long list of valuable perks, including a new and highly versatile Global Companion Award benefit, plus 3x back on 'foreign purchases.'

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.
