Alaska Airlines is overhauling its Mileage Plan.

If you are a frequent flyer on Alaska Airlines, you’d probably rather appreciate the changes as they make the program more valuable for you, such as an eased tier qualification.

However, if you used the program mainly because of the generous credits in premium cabins on its partner airlines, the party is over: These bonuses were harmonised – at a high level – cross all partners – but only continue to apply if you book these flights through Alaska Airlines. Technically, you can do this only for flights to/from North America. For any other booking channels, they were reduced dramatically and even Economy Class full fare tickets now only earn 50% of miles flown.

A harmonised award table across all partner airlines will be introduced as well. It has not yet been published, but it is for sure that the sweet spots of some of the individual tables will disappear.
