Airplane carriers have faced some criticism for removing passengers who are already booked on a flight. Some have argued that it is a violation of the contract to carry law while others put it down to bad customer care. Recently there was a particularly embarrassing incident when a passenger was forcibly evicted in such a violent manner that he sustained significant injuries, which were then shared with the world via social media.
From a legal point of view, the question was whether the actions of the carrier were justified and legal. This is the intersection of civil liberties and consumer protections. For example, there are questions about whether a carrier can arbitrarily refuse to carry a passenger. There are exceptions that are based on security considerations, but more often than not, the issues in the USA involve overbooking. The behavior of the carrier representatives can also constitute a cause for criminal and civil action.
