The attacks on airline crew and airline employees both inflight and at the airport is out of hand. An attack on one airline employee is an attack on all airline employees, regardless of airline. No crew or airline employee of any airline wants to deal with these people who punch, threaten or cause disruptions on flights or at the airport. Enough is enough. We want the airlines to share their no fly list so if a passenger gets a lifetime ban from one airline, they get a lifetime ban from all airlines. They can take the bus or drive or walk.
