...and if you will take a flight one day later we will guarantee you and your son an upgrade. This didn't happen to me, but it DID happen to my brother a day ahead of his scheduled departure. Not sure of their routing, but they are flying IAH to KOA. Has this happened to anyone else? My thought is he should have asked for more (like miles or something), since he is a gold and probably had a shot at the U/G anyway unless of course, he is on the IAH-HNL flight.
