What this relates to:
International aviation authorities such as the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA) have strict regulations to address unruly passenger behaviour, and airlines follow a zero-tolerance policy. Unruly passengers on board an aircraft engage in disruptive, violent or non-compliant behaviour that interferes with the safe and orderly operation of the flight. This can range from minor disturbances to serious threats that endanger the crew, passengers, and aircraft. Examples include refusing to follow crew instructions (e.g. not wearing a seatbelt, ignoring the smoking ban), engaging in acts of verbal or physical aggression toward crew members or other passengers, becoming intoxicated and behaving disruptively and making real or hoax threats (including bomb threats or false claims of danger). Possible consequences are fines and legal prosecution, financial liability for costs incurred due to delays or diversions, and permanent bans from airlines.
Example:
A passenger is caught smoking a cigarette in the cabin or toilet. He is advised by the cabin crew that this is not allowed and is asked for his personal details and passport. He refuses to give his details and becomes very aggressive and violent. The pilots inform air traffic control that the police will be needed on arrival. After landing, the passenger is taken into custody by the police. The passenger can expect to be prosecuted and fined.
