Something you might factor into consideration is the very inconsistent treatment of AA Plats on Alaska. Also there is no upgrade recognition.
Oh, an aside. The recent trend on FT and certainly this board is to get flamed for the audacity to ask a question previously posted, regardless of what you post. Search is an art not a science. My response to these people is simply that I hope they feel bigger. I got the info I wanted even though you thought I was unworthy. So Nyah Nyah.
