First class to no class?

Watch the video (click above) and judge for yourself whether this teenager was behaving in a way that would make him a "flight risk" sitting in first class with his parents on an American Airlines plane. To make matters worse, when the family was rebooked on a United Airlines flight, they found themselves seated in the back row of the plane with two empty rows of seats in front of them. For the protection of the other passengers? From first class to no class?
