I think this is related. Had a flight change alert today. LHR-ATL DL31 on Dec 12. Now leaves LHR 90 minutes earlier (12:30pm instead of 2pm). Is it reasonable (possible) to ask that I be moved to leave the next day Dec 13? There is a later flight at 3:30pm DL33. But, I'd really prefer to add a day, without paying the fare difference. Has anybody had any experience with that sort of thing. Yes, I could call, but asking here is more fun :-).
