I know if there's an answer to this, FT folks will have it. so I've had THREE red-eye flights in the past week. on ALL THREE, I checked and confirmed my window seat the day before the red-eye portion and my seats were intact. on all three when I checked in at the airport kisok, I had been mysteriosuly changed to a middle seat. Not happy since I really planned on sleeping. In each case it was due to an equipment change (red coat explained this to me today/last night). So i understand that DL reserves the right to change equipment on any route at any time but my only "beef" is that it seems like they'd know this - in most cases - more than 24 hours in advance and hence it would let the traveler choose different seats. so my ? is can I do anything in the future, particualrly when taking red -eyes, so that automatic seat changes don't end up in a middle seat? I think it's fruitless to make this "Delta's issue" and expect them to do anythiung but is there anything I can do to be proactive? Thnx.
