Searched for thread with this issue but didn't find anything specific.

Flew ORD-RDU Friday night. Booked 3 months ago evening flight on mainline. Got email 1 month ago flight was changed to e145. Email confirmed I had been put in row 12 emergency exit row (12 and 1 only extra legroom rows on e145). I checked reservation and confirmed I was in row 12.

Checked reservation a few days before travel and it says I'm in row 14 with 12 occupied. I call up, agent checks with supervisor and "sorry our computer moved you for an unknown reason during the month." She kindly offered to put me on earlier flight (I appreciated the offer to help in some way) but it was at 1pm and my booked flight was at 7pm.

I know I've read threads where people said check your seat assignments daily but I hadn't seen this complaint in a while so I thought those issues were somewhat resolved of SHARES randomly dropping seat assignments. Has this still been happening? Can't they have some sort of redundancy that allows this to be caught?? Especially for their most loyal customers!

I have to say that I find it a sad state of affairs when a customer feels compelled to check their reservation every day due to lack of trust. Definitely not feeling appreciated.

"You're great at taking reservations. You just don't know to HOOOOLLLD the reservation. And that's really the most important part."
