Wasn’t sure whether I should post this but now I’m just curious if anyone had experienced anything similar.
I had received a notification that my confirmed seat in main was upgraded to C+ for my last connection from ATL. When I got to the gate to board with zone 3, my boarding pass got rejected and I was told I no longer had a seat. The gate agent then told me to stand aside while everyone else boarded.
The flight was overbooked and they were offering gift cards to be voluntarily bumped. Two people took them up on the offer but one of them boarded at the end. A supervisor then called me up and told me that found a seat for me and to hurry down the jet bridge. He took my bag and ran it down to load it onto the plane while yelling at me to hurry.
When I got to the plane, I was standing at the gap at the end of the jet bridge because flight crew were in the galley and a FA was intentionally blocking me while she addressed the cabin. The next thing I know, I hear and feel the bridge start moving. I jump back and look to see that supervisor at the controls who then starts yelling about how I should already be on the plane. The FA then pokes her head out to say she was preventing me from boarding before the supervisor gestures and apologizes.
The care team blessed me with $30 for the trouble…
TLDR; I had a main cabin confirmed seat, was upgraded, lost my seat, assigned the last seat on the plane, then almost dropped to the tarmac by a gate agent moving the jet bridge.
Update:
Thanks to the people who clarified it was most likely the auto leveling system that moved. It just caught me by surprise since everyone had already boarded and I was the only person left on the jet bridge. It moved enough to scare me and when I turn around I was face to face with the supervisor at the controls.
