The screaming and shouting aboard that United flight from Chicago to Louisville has caught the attention of many indignant people. Why was the passenger treated the way he was? Unfortunate as it was, there’s a reason. United had to clear seats for staff who were being shifted to Louisville to crew a later flight. If they didn’t go, the flight would have to be cancelled. It is standard stuff. And so is the method used to find space on a plane when it is overbooked. The police (not airline staff) handled the passenger the way they treat anyone who refuses to do what is asked. They forcibly removed him. Some will say his behaviour bears on a temper tantrum.
