Was flying SLC-RDU the other day with a connection in BOS. Lady at Skyclub told me SLC-BOS was oversold by 8. Left early, headed to the gate, agreed to a VDB on the condition of being rebooked in full F/J via ATL and $200 which was great since I'd be getting home early and would be making money.

However when I got to the gate for Atlanta, I was assigned a economy seat. When I told the GA that I had VDBd in exchange for a seat in J, she told me that there was no seat left in J and that the other GA had made a mistake and changing class of service was illegal. At that point they also needed volunteers for ATL but the only alternates would have gotten me into RDU the next day which I didn't want.

I got the extra miles for the rebooking in J and F on the two segments home, but I'm bummed cause I had already been flying for a while and was incredibly tired and was really hoping to relax and sleep on the long transcon. I'm worried if I complain to DL I'll get my class of service MQM and RDM removed. Worth it?
