Check out the terms of the contract the phoney drama queen agreed too, specifically the sections on why he can be kicked off and limitations of damages.
Once he is given a boarding pass and is in his seat, the rules change. There is a very specific list of reasons (rowdy, drunk, smelly, barefoot, etc.) that he can be kicked off the plane at that point, and the airline needing his seat is not one of them.
Now still at the gate is another story, and another set of rules, as is overbooking, which this was not.
Sorry but the fact is Planes fall under Train laws. And No his contract controls plus hes a phoney. Full Videos show its a shakedown.
