Then there were the two female twins from Buckley, Michigan who diverted a UA flight ORD/Shanghai after being drunk, smoking in the lav and fighting with passengers and the crew. The video was all over the place, and they were seen slurring that they were going to Shanghai on a free ticket for a "modeling competition." The word locally (Buckley is just S. of TVC) is that someone on the flight warned them that there was no "modeling" involved in the trip that they signed up for, and that they caused the disturbance to get out of the trip.
Perhaps not totally true, and slightly OT, but something for one to consider.
