In this case, it wasn't about overbooking.If I were to guess, whether or not the plane is overbooked is irrelevant. If asked to get off, you have to. There are far more reasons than just overbooked flight that you could be asked to get off the plane. You can't set a precedent where you can start to argue with the flight attendants and flight crew. That will set a dangerous precedent.
No, it does not set a dangerous precedent. The man knew exactly why he was being asked to leave. It wasn't an emergency. They simply overbooked the flight. I'm glad he stood up to this bullshit practice over overbooking flights.
Oh yea, even worse. They bumped paying customers to fly their employees somewhere. In either scenario they can still shove that contract up their asses.
