When United Airlines had a paying customer violently removed from a plane just because that customer wanted United to honor its promise when he paid for his ticket, United was well within its legal right to do so. It says right on the back of your ticket, in print most people over the age of 45 cannot read, that paying customers can be asked to give up their seat if the airline needs to use it. In this case, the airline needed to transport a crew or that crew's flight would have been moved to the next day. United says that it was within its legal right to inconvenience one passenger to accommodate 150 others, but I am not sure that is the point here.
