I got bumped but they offered me a seat on another flight "just down the terminal" but told me to RUN to try and make it as they were holding the plane for me. Got there and they were waving me thru no room for my luggage. In the rush I grabbed my jewelry out of the bag but forgot my $300 BMW car keys.

The plane sat in line for an hour waiting for take-off making the connecting flight very very tight which is where I think it got lost.
My bag has never been seen again..... It was after midnight when I arrived back at my home airport, waiting around for an hour for the next flight hoping that it would be on that then finally had to check into a hotel as I wasn't about to call someone in the middle of the night to come pick me up.
I couldn't find my ticket they handed me in the rush to board, this was not my normal airline and they never would reimburse me for the bag.
I try NEVER to gate check a bag now if at all possible.
