I did not expect an U/G. I know what the rules are. But I do know that people on lesser fares (Latitude) get upgraded automatically without an U/G certificate. If AC were interested in treating its loyal and high-revneue customers better, this would not have happened, and the responses on this thread confirm this. I am just very dissappointed in AC. If there was a choice in full-service domestic carriers I would walk in a dime store minute.
