I was also on that flight. I saw the "important person" but couldn't tell you who he was. I did notice when we pulled into the gate that there was a police cruiser waiting on the tarmac below. When we exited the plane (we were in the back) there were 2 security type personnel at the door of the stairs that led to the ground below. I do know for a fact that the 20 minute hold up on the ground was not due to the VIP, it was due to 2 little middle eastern kids that were very uncontrollable. The mother couldn't even raise her head to look anyone in the eye and the father couldn't speak any English. This family tried to sit themselves in the middle row. The kids were hanging all over the seats in front of them and behind them and refused to put on a seatbelt. After several moves and readjustments they removed the HUGE suitcase from in front of their seat and shoved it overhead. Unfortunately, we were sitting right next to this family. Needless to say it wasn't a very pleasant flight.

On another note there were a lot of African delegates on the plane, not sure if they were there with this VIP or not.
