Inoperable Seat...Was I IDB'd
Was booked into upgraded F on a PS flight. The SFO flight that I was on announced a maintenance delay so I tried to get on the LAX. Went to the LAX gate agent and was told "I'm working this flight, have the platinum desk do it." I called up the platinum desk and they put me on. When I went back to the desk she said "we don't have a seat for you." I was told that one of the seats was totally inoperable and unsafe for a passenger to sit in. Thus, there was no room on the flight. They claimed to have blocked the seat and that somehow the platinum desk unblocked it, and it was their (the desk's) fault for all of this. I went to a service director, and he said the same thing, that it was the platinum desk's fault, and that I should have them rebook me.
Is this an IDB and should I have been compensated under DOT regs? If so, what should I do now?
