I noticed you got upgraded for *G as well. I did too on one of the segments. I questioned my AE contact if that could be the problem as maybe the booking class they were searching for was incorrectly entered (flown different from booked). She said that wouldn't be a problem... but I don't know...?

Also one of the mights was canceled and I was reassigned to a new flight #... I questioned if that had caused an issue too? She said it shouldn't.
