CONCLUSION
Despite the complexity of the issue, there are practical steps that an airline can take to prevent and manage unruly passenger incidents. Cabin crew are in a unique position when it comes to dealing with the unruly passenger problems as they are not able to escape the situation or to call for the authorities for assistance on board during flight. The emphasis on unruly behavior of passengers should be one of prevention and with strong emphasis in doing so from the arrival at the airport through to the passenger cabin of the aircraft in order to best mitigate incidents, and when possible, to keep the unruly behavior on the ground.
A collective and unified approach by the aviation industry would result in significant improvements to the problem of unruly passengers. It is incumbent on all persons within the aviation industry to realize that this is a very real and serious safety issue, and to closely monitor and report any event that may result in the unacceptable behavior of passengers while in flight.
But each airline must send the cabin crew to training in everything but have one point that most important are Aviation Security Training and Self-Defense Training.
