Atmos Rewards, the new loyalty program from Hawaiian and Alaska airlines, has officially taken off as the singular way for flyers using either airline to earn points, benefits and status. HPR's Emma Caires breaks it down.

The new program, called Atmos Rewards, took effect for Alaska Airlines customers on Thursday. HawaiianMiles members will transition to Atmos on Oct. 1.

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.'
