I went online to check in for an early morning flight tomorrow and was surprised to not see any upgrade list showing after check-in was completed. Nor was and there an "upgrade requested" showing for my return flight later this week. When I called the Platinum line, I was told that it was a computer glitch and that they can't put me on the list now becuase the glitch is irreversible (???), but that they have put in a note with my reservation and that I could "request an upgrade at the airport" ???? How the h@$#%# is that supoosed to work?!?!? Do GA or Check in people have any control at all over the upgrade process?? On the off chance that i should have gotten the UG, how would I make sure that I get it or get compensated if I don't?
