I was waitlisted on a YYZ-YYC flight last Wednesday. My wife (one of my nominees) was also waitlisted as expected. I requested the UG right at the 7 day window. The UG did not clear in advance (surprise) even though J=9 at that time. In the MLL lounge in YYZ, the agent said I was number one on the list (as SE and ACMM) but my wife was much further down the list, which she thought was odd since we were on the same reservation. At the gate, the GA called my name and said there was one seat available due to a misconnect from MIA and did I want it. I said I would take it and let my wife sit there, which was fine with him. Nothing unusual so far, but I've been checking my e-upgrade account daily to make sure the credits were returned to my account and up to now, they still have not been credited back, and in fact, we're still shown as being waitlisted on the flight in question. How AC can have such an incompetent IT department boggles my mind.
