It's like United Airlines said, "Yeah, we don't want people to fly on our airlines anymore. What can we do to ensure our business utterly fails?". I mean, there's so much wrong here:
1) They overbooked to begin with.
2) They end up giving their own employees preferential treatment by kicking off passengers for them.
3) The compensation for the delay would be $400 which is nothing when it comes to rebooking plane tickets. It was upped to $800 and a hotel room, but still...
4) They end up beating up some old dude and dragging him out of the plane.
5) The dude was a doctor who was on his way to help sick people.
