Arrggggh

I got FAM'd today coming from ATL-BWI. I landed in ATL and saw on DL.com (via my BB) I cleared into F on the next leg. I get to the gate and the GIDS showed me still in F. They board zone one and I get the PAX NOT CLEARED error on the machine. GA pulls me aside and tells me "There were two last minute FAMs who needed your (and one other PAX) seats". Of course by that point the GA had already released my exit row aisle seat, assigned it to someone else and was now looking for volunteers for the flight as it was oversold.
I made the flight but ended up in the middle of the last row on at 757 ... I almost wished they would have IDB'd me instead as it would have been better than the middle of the last row of the flight I was on.

I just needed to vent and I dont think this warrants a new thread
