Airline Industry Sees Spike in Unruly Passenger Behavior Fueled by Vaping.

Unruly passenger incidents on planes have increased by 37% year on year, with non-compliance, verbal abuse, and intoxication being the most common types of incidents, according to a global analysis by the International Air Transport Association (IATA). Smoking of cigarettes, e-cigarettes, vapes, and “puff devices” in the cabin or lavatories was the No.1 non-compliance issue highlighted by the IATA. The aviation body is calling for a zero-tolerance approach to unruly behavior and wants more countries to ratify Montreal Protocol 2014, which allows for the prosecution of these transgressive passengers.
