I booked my trip to FCO on Jan. 14th of this year, and was assigned seat #24A for the PHL-FCO and FCO-PHL legs on the A330. I'm travelling alone.
I checked my reservation the other day, and found that the seat had been changed on the PHL-FCO leg to #33H, which isn't as good because of where the seat's located at the back of the plane (fusealage narrows at that point). No other seat changes were made to the other three flights I'm booked on.
I called US to see if they could tell me why I was bumped out the of the seat I was given back in January, and they couldn't tell me, or share the exact reason. I was offered some other aisle or center seats, but no other windows.
Any ideas as to why US changed the seat on me like this? At least with UA, I can select my own seat, but I couldn't even do that when I made the reservation on US.
