The UK government is preparing to take a tougher stance against passengers who disrupt flights. The plan includes creating a database to record disruptive passengers. If this system is implemented, airlines will be able to report problematic passengers to authorities. When the same person tries to check in for another flight later, other airlines can be informed of this situation. Then companies can decide what to do about the passenger based on their own assessments. This will make it harder for a passenger banned by one airline to fly again with another company. Aggressive or intoxicated passengers on planes have long been seen as a serious problem in the aviation sector. Especially in Europe, there is increasing pressure to take more measures on this issue. In April, a Jet2 flight from Turkey to London was diverted to Bulgaria due to inappropriate behavior by two passengers. The company announced that it had placed the two passengers on a lifetime flight ban list. At that time, Jet2 also announced that it was working to establish a national database that could be valid not only on its own flights but also on other UK airlines. Ryanair CEO Michael O’Leary said last month that alcohol has become a major cause of problems on flights and advocated for a two-drink limit per person at airport bars. O’Leary also criticized the serving of beer early in the morning at airports, calling it unnecessary. It is noted that being intoxicated on a plane is considered a crime in many countries, and violators may face fines or imprisonment. Jet2 and Ryanair reported that they are also trying to recover costs arising from passengers who cause flights to be diverted to other cities. These costs include fuel, passenger compensation, and in some cases overnight accommodation. Ryanair filed a lawsuit in 2025 seeking compensation of over $15,000 from a passenger who forced a flight to change direction. In the same year, it also requested fines or imprisonment from a Spanish court for another passenger who allegedly caused a delay by trying to sit in a seat that was not theirs. Problematic passengers cause headaches not only for airlines but also for regulatory bodies. The US Federal Aviation Administration proposed a $165,000 fine to Alaska Airlines last Tuesday, reporting that the company allowed intoxicated passengers to board 11 flights between February 2024 and February 2025. Alaska Airlines announced that it has increased training for cabin crews and customer service staff and made significant changes to its practices to comply with authorities. A British source stated that the aim is to more effectively combat individuals who constantly cause problems on flights.
