First, Alaska dumped Delta (or maybe the other way around)? Now, they are dumping AA.

A shame - I have used Alaska miles to fly to Europe for the last several years, and I took advantage of their free stop-over to be able to stop on the east coast on the way to Europe - and there are many direct AA flights from PHL to Europe. This after Alaska devalued their frequent flyer program by removing the "free changes up to 60 days before departure" policy that I also used to take advantage of.
I have some remaining Alaska miles that I guess I can use to fly on other carriers to Europe. But I already use Southwest to fly domestically. I guess I'll use up my Alaska miles and move on to another airline program.
