The united airlines incident which has caused an internet sensation, were they pulled out a boarded passenger since their flight was over booked, was a terrible way to treat a passenger, this could happen to any one.

I think when a passenger has been allotted a seat and is sitting down on his or her seat, no one should touch the passenger, unless the passenger is the one causing the problem.

These days the airlines keep doing something stupid, finally the airlines has decided to review their policies and says it will no longer allow employees to take the place of civilian passengers who have already boarded overbooked flights, and crews should be booked at least 60 minutes prior to departure.
