Update:

I spoke too soon on my chances of getting upgraded on BZN-SEA. I'll now be in first class on the whole trip home to oklahoma.

Although it only appeared there were one or two seats remaining in the first class cabin for almost 2 weeks now, I got an email this morning saying that I had been upgraded. One of the reasons I chose Alaska is because I needed to fly on sunday. I knew there was very little chance I was going to get upgraded on american, so I thought I'd give them a shot. It paid off.

It appears that Alaska treats American elites better than American treats American elites.
