Happened to me back in the day with Lufthansa at Frankfurt. I had a delayed flight and connecting flight was on the other side of the airport. Had to run through immigration, and security. With my belt and laptop in my hand to the last gate in the far end pier of the airport. I managed to arrive as one of the last 3 people to pass the gate which directed us to a bus and took back to the same plane.

The steward who I had chat before was laughing his ... off and told me he couldn't help with this but at least he can bring a bottle of wine right away...
