I am a US Airways Chairman's Preferred member, but am considering to switiching to
AA and become an Executive Platinum. Based on your experience, how easy is it to get upgrades on AA? On US Airways, I upgraded almost 100% of the time (7 days in advanced). Is it that easy to upgrade on AA?

Also, what are the upgrade rules for Executive Platinum? How far in advanced can you confirm upgrades (on US it is 7 days in advanced unless on full fare, then its at time of booking)? Do you have unlimited upgrades or do you only get a certain amount (unlimited on US)? Also, do you have international upgrade privleges (none on US), or oneworld member airline upgrade privleges?

Final Question: Can anyone fill me in on the benefits on Executive Platinum (Emerald) with oneworld?

Thanks so much for your help!
