The Atmos Rewards Summit is the new premium card offering from Alaska Airlines and Hawaiian Airlines, with many unique perks for frequent flyers. Here are the details.

Alaska Airlines is launching a $395-a-year rewards credit card as it joins the industry's race for high-spending customers. It is also launching a combined loyalty program with Hawaiian Airlines, called Atmos, and raising requirements for elite status. Alaska acquired Hawaiian last year and plans to keep the two brands operating separately.

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.'
