So, our flight to MIA has been sitting at X1 since the 100 hour EXP window. PLT window rolls around, and no upgrade, but still at X1. There are 2 of us. I kept checking, and around 8am, it went to X3. A quick look at AA.com still had lady astrojets and me in Y. Got on the phone and hit the upgrade phone system, and got the magic words "your upgrade is confirmed."
Not saying that it wouldn't have happened on its own, as our requests were in for several weeks. But I have to say that I like expertflyer a lot!!!!
