He paid for a service, and they have to fulfill their service. They did not.

So he was a dick for trying taking the plane he paid for? I guess everyone else on that flight as well, since no one wanted to get off the flight.

They have the right to refuse service. If you don't believe me, how many times have airlines kicked people off of planes?

They asked him nicely and offered him a good deal to get off the plane. He refused. They asked again. Refused again. Like I said earlier, what did he honestly expect from refusing? It was gonna play out in one of two ways. He gets off the plane willingly and takes another flight or he's forcibly removed and likely arrested. This isn't like an arguement with a spouse, being stubborn won't get ya anywhere.

Yes, they could have refused service by not accepting his money. However, they did, so they entered a contract.

This shitty airline, the three security agents who removed this man in this way are garbage. I advise anyone never to ever use this airline. That way they don't have overbooking ever again (which should never have happened in the first place if they were competent).

At the very least they would need to refund his ticket, and give him another for a later flight.

Also such moves can be a problem, if the person in question has a time & place he needs to be at.

Its a really dick move by a air plane company to do this.

If a guy refuses to be kicked off, they should have first started asking other passengers, before resulting in dragging a man out like that.

They did claim that :p

He "fell" into that arm-rest, it wasnt because 3 guys where pulling on him and banged his head.

Now, you're just being silly. 

I'm sure the airline was gonna do all sorts of nice things for him because they were gonna move him to a different plane. I saw in one of the other posts that he was more or less told there was a chance he would have to change planes, he bought the ticket anyway. I don't know what happened in the exchange between him and the airline staff after he was told he had to leave. He could have been real nasty about it. It doesn't really matter for the most part. The important part was that he was told that he had to leave and he refused. They had to remove him forcibly because he refused to go the nice way. 

My point is if I took a cab and I paid for the ride beforehand but the driver told me that I had to leave later on, I would ask for my money back. If i got it back, i would leave with no arguements. I would just get a different one. If he was nasty, i would write down his cab number and call his company later on to complain about him. 

As a liveleaker, I've seen much worse shit.

If you don't have enough seats for everyone, tell that the last four people who try to enter the plane and refuse to let them enter it if you really have no seats for them. 

If you have some employees who want a seat the last seconds before the plane is going to takeoff, don't be so stupid to throw people out of your plane just to let them get a seat. It's not only stupid for your reputation but also pretty disgusting to even handle your customers like that for such a reason.

People could lose their jobs if you just throw them out of the plane so that they will arrive too late to get back to work. Your employees don't have such a problem, you know they can't fly because you weren't able to have enough seats left or them.
