Was looking at a flight from PHX-ORD leaving this afternoon at 5PM local time. I looked at avail about 5 1/2 hours out and according to expertflyer, avail was F7 X0 A1 P7. I checked again about 4 1/2 hours out and it read F0 X0 A0 P0.

So did RM decide to release all the first class seats at that time and all outstanding upgrades were confirmed by priority?
