Alaska Airlines and Hawaiian Airlines have launched a joint loyalty program called Atmos Rewards and introduced a new premium co-branded credit card, the Atmos Rewards Summit Visa Infinite, as part of a broader repositioning to serve more global and premium travelers.

Alaska Air Group Inc. debuted a new loyalty program that will let members choose from three options to earn award points, the first such offering in the US industry.

The announcement marks another step in the airline’s effort to transform into a global carrier after merging with Hawaiian Airlines last year.
