(Central News Agency correspondent Guo Fangjun, Zurich, 5th) Incidents of unruly passengers threatening aviation safety in Switzerland are on a continuous rise, with cases surpassing 2,000 in 2025. In addition to increases in alcohol-related incidents, violence, and rule violations, conflicts triggered by passengers traveling with dogs are also growing. As the peak summer travel season begins, the aviation industry faces new challenges in maintaining passenger order.
According to the latest data from the Swiss Federal Office of Civil Aviation (Bazl), incidents of unruly passengers on board, including verbal abuse, physical assault on other passengers or crew, and non-compliance with flight safety instructions, have been steadily increasing in recent years. Statistics show that cases reached 2,021 in 2025, a 17% increase from 2024. In 2024, cases had already increased by 30% from the previous year, indicating a worsening trend.
Safety incidents caused by unruly passengers occur almost daily, with verbal attacks on flight attendants being the most common, totaling 518 cases. Other violations include failure to follow rules such as fastening seatbelts or turning off electronic devices, smoking violations, alcohol or drug abuse, passengers consuming their own alcoholic beverages, as well as violence and sexual harassment incidents.
Swiss Radio and Television (SRF) recently noted that not only is the number of unruly passenger incidents increasing, but their severity is also escalating. In a recent incident on a Swiss International Air Lines flight from New York to Zurich, a Belgian passenger demanded entry into the cockpit after takeoff and attacked flight attendants and other passengers, injuring several crew members. The captain requested a return for safety reasons, and the flight ultimately made an emergency return to New York.
The passenger was sentenced on the 1st by a New York court to 10 months in prison and fined $70,000 (approximately NT$2.2 million) for charges including destruction of cabin property.
Swiss International Air Lines spokesperson Michael Pelzer stated that the airline is pleased with the US court's verdict, emphasizing that any violence against crew or passengers is unacceptable.
Furthermore, as the number of passengers traveling with pets increases, related violations are also rising. According to the Swiss daily newspaper Tages-Anzeiger, an Italian passenger was fined 400 Swiss francs (approximately NT$16,000) for refusing a flight attendant's request to keep their dog in a transport crate.
According to Swiss International Air Lines regulations, certified guide dogs or service dogs are allowed in the cabin free of charge regardless of size, but must follow commands and not cause disturbance to other passengers. However, not all passengers understand the needs of passengers with service animals, leading to increased conflicts. Bazl data also shows that incidents of unruly behavior caused by passengers with dogs reached 117 in 2025, a 46% increase from 80 cases in 2024, outpacing the overall growth rate of unruly passenger incidents.
