He says he has patients that needed him the next day, there were flights to the same destination after a few hours so he should have still made it in time.

When he said this, i think the flight crew should have picked someone else, or just not fly their employees (I'm told it was infact not overbooking but they had to fly 4 off-duty employees to point A so they could start working on a different flight)

I think the airlines are wrong in asking people to leave and not even due to overbooking (If it was overbooking they wouldn't eject people i guess, the people not on the plane would be the ones out of luck.) at the same time, onces it had reached boiling point and was clear there was no room to discuss it with the flight crew, he should have left like the other 3 people, instead he had to be removed by those whose job it is to remove people ignoring flight crew instructions because it seems to be a federal crime or some shit.

I put 99% of the fault with the airlines for starting the whole situation and 1% with him being stubborn to the point forced had to be used.
