Cases of In-flight disturbance have been increased significantly in recent years and there are many signs that it is getting worse. In light of the fact that any unruly and offensive behaviors by passengers may harm the safety of other passengers and airline employees as well as that of the judicial authorities of many countries, airlines and international organizations. Commercial air carriers are in the best position to enact and implement safety and security measures that would deter dangerous passenger behavior Airlines should immediately change certain practices and implement new policies and procedures for identifying and responding to potentially disruptive passengers. Airlines should adopt policies and procedures for handling unruly passenger behavior, such as those suggested in the IATA guidelines. These policies and procedures must be supported by on-board mechanisms for monitoring passenger behavior. Passengers should be advised that the airlines will not tolerate certain prohibited behavior. Passengers should be given written notification of violations, and the airlines should readily enforce the available criminal and civil penalties when incidents occur. Airlines should make this information available at airline counters, at the gates, and in airline in-flight magazines. Preventive measures can impact the number of violent incidents that occur on-board commercial flights.
