Alaska Airlines is shuffling the deck with its popular Mileage Plan loyalty scheme. In a pitch to customers of both Alaska and Hawaiian Airlines, the carrier is rolling out its new Atmos Rewards plan. What does the new loyalty scheme mean for you?

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.'

Alaska Airlines introduced Atmos Rewards: its own (and Hawaiian Airlines') loyalty programs, and a new high-end credit card as a means to woo high-value flyers. The expansion puts Alaska on more equal footing with bigger carriers by growing its footprint and providing increased benefits, destinations, and flexibility.
