On August 20, both airlines announced the launch of Atmos Rewards. By October 1, 2025, Atmos will replace both Alaska's Mileage Plan and Hawaiian's HawaiianMiles as the united loyalty program, promising new ways to earn points and elite status, along with new credit card perks.

Alaska Airlines is out with its long-awaited new loyalty program, Atmos Rewards, which combines the former Mileage Plan and HawaiianMiles programs.

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