I have a friend, going on his honeymoon, who is flying NW58 MEM-AMS tonight (9/11) and was given a run around by Delta agents over the phone when there seats disappeared. They had seats 10AB on the A333 when they made the reservation. When they went to look at the reservation 23 hrs before departure it showed them in 34 DE. They called Delta and was told the reason the seats had changed was because it was a aircraft swap. (I looked on flightaware and this flight was an A332 until 9/1 where it switched back to an A333. Shouldn't matter as row 10AB is still bulkhead/ exit.) Then at 13 hrs before departure there seats got changed to 11AB and within an hour were then changed to 18HJ automatically.

Is this the way Delta handles seat assignments? They can switch seats around at anytime because they feel like it. I told my friend to check in online to hopefully lock in there good seats. Hopefully they wont get changed again. Not a good way to start a a honeymoon with 5 calls to Deltas "Top Notch" reservation center.
