Thanks for you very informative post. I have been on the phone tonight to Alaskan Air to try to get to the bottom of this. I wish to travel on two tickets (one is an Exec Club reward) LHR-SEA-Kelowna. As you say Alaskan are a "partner" of BA but not OW. From reading your post I assume my journey is in the possible but not required category.

Alaskan say I should ask BA if they intend to check by bags through. I'm on a "legal" connecting flight with a 2h 10 lay over. I'm not motivated by avoiding the charges but by the difficulty of passing all the way out of the airport and then all the way back in. This will probably make my connection too tight and the next flight is 10h later. Through bags can be rechecked straight after U.S. Customs at SEA.

In reality, does anyone have experience of BA interlining with Alaskan? what are my chances? My BA flight is club world if that adds anything to the show.

Thanks for any advice.
