My husband and I are on the same flight tomorrow. Two different reservations as I am flying somewhere else first to drop the kids off at the Grandparents. We meet in ATL and continue on to PBI together.

I double checked no less than 3 times during the booking process that the flights were the same. I picked our seats in exit row together, me 27A and him 27C. When I made the reservations and picked the seats, I am 100% positive that it showed the same as I almost always go for 27A because I like the easy access to the bathroom plus the window seat (in fact, I�m 27A on all 5 flights I have tomorrow) and I would have noticed the different exit row on the seat map.

Now today, his reservation is showing a different seat map for the same flight. His seat is still 27C. Both flight details still show an A321.

I have refreshed and quit the app a few times. Flight radar also still shows an A321.

My thoughts are:
1. Technical glitch
2. Aircraft swap that is showing the new map on his but not mine yet?

Any thoughts? Mine on top, his on bottom.

Your seat map is an a321 and the other is a 737-900. Flightaware shows your flight as being an a321 (N103DY). So seems like this is a technical glitch in your husband's seatmap.

I have no idea where the second seatmap is coming from. Looks like a 739.

Currently assigned tail, scheduled type code, GDS seatmap, and seatmap for purchase on dl.com all show a 321, which is consistent with what you see.
