That's not the way the game is played. If there aren't enough seats, the airline should keep raising the promised rewards for moving to another flight, until they are high enough to get passengers to choose to accept them. And by all means, you don't take someone off a flight who is already seated. This is reprehensible. Sell your United Airlines stock immediately. This company has no idea what they're doing.
