Alaska Airlines has changed how elite status will be earned in 2021. Alaska used to require more miles flown if you include miles on partner airlines than if you’re using miles flown exclusively on Alaska. That’s gone.
Starting in 2021, Alaska and partner flights will count the same towards elite status, and the lower “Alaska-only” status requirements apply. But they’ll require a minimum number of Alaska flights for status – to keep low yielding American Airlines flyers from just dumping their American segments into Alaska.
