Thanks so much everyone! I'm glad I started this topic, as it has been very interesting and informative. I sure am bummed that I can't fly w/mile upgrades on AS's partners though, after getting my hopes so high.
Uugh... now I'm wondering if I should not go with AS as I had planned. Maybe NW or AA would make more sense if I want to upgrade to F on int'l flights? Just look at me, you guys have turned me into an F person now!

I better be careful how I use that letter.
*sigh*... back in a state of indecision. I can see I'm going to have to do a lot more research and digging.
