Alaska Airlines and Hawaiian Airlines have unveiled Atmos Rewards, a joint loyalty program uniting both carriers under one platform. Members gain access to flexible rewards, lie-flat business-class upgrades, and a new premium credit card offering lounge access and global companion awards. Replacing HawaiianMiles and Mileage Plan this October, Atmos Rewards streamlines benefits while supporting the airlines’ global expansion—positioning them as strong competitors in international travel and reshaping loyalty in the U.S. aviation industry.
