There are some articles written by attorneys or based on attorney's comments that say that the language of the contract is not as broad as believed. For example, it talks about barring people from boarding. And it talks about flights oversold or overbooked but not about airline employees who are simply boarding and being added to the passenger list when they show up. It appears from the language that the airline's right extends only to stopping ticketed passengers from boarding. This means that they do not have a legal right to physically assault them or drag them off the plane to get them out of their seat and out of the plane. And the Airline does not have right to retain agents like the police or airport security to remove passengers when they have no right to assault or legally kidnap them (kidnap in the legal sense).
