ANA Flight Diverted After Midflight Exit Door Incident
All Nippon Airways flight diverted to Seattle after passenger attempts to open emergency exit midflight, highlighting aviation safety protocols.
In a serious aviation incident, an All Nippon Airways (ANA) flight en route from Tokyo to Houston was diverted to Seattle after a passenger allegedly attempted to open an emergency exit door midflight. The event, which occurred on May 24, 2025, underscores the critical importance of in-flight security and the challenges airlines face in managing passenger behavior on long-haul international routes.
While commercial aircraft are designed with safety mechanisms that make opening doors midflight nearly impossible due to cabin pressure, any attempt to tamper with emergency exits is treated as a significant security threat. The incident prompted swift action from the flight crew, passengers, and law enforcement, reflecting the aviation industry’s strict protocols for handling disturbances.
Incidents involving unruly passengers have been a concern in recent years, and this event highlights ongoing challenges related to airline safety, regulatory practices, and passenger mental health considerations.
Flight NH114, operated by All Nippon Airways, departed from Haneda Airport in Tokyo at approximately 10:33 a.m. local time on Saturday, May 24, 2025. About nine hours into its journey to George Bush Intercontinental Airport in Houston, the flight crew reported a disturbance involving a passenger attempting to open an emergency exit door. The aircraft, a Boeing 787-9 Dreamliner, was diverted and safely landed at Seattle-Tacoma International Airport at around 4:19 a.m. Pacific Time.
According to the Port of Seattle Police, the individual was restrained by passengers and flight crew, with two military veterans reportedly assisting by zip-tying the passenger to his seat. Upon landing, the person was evaluated and determined to be experiencing a medical crisis. They were transported to a local hospital for further care. A second passenger was removed from the aircraft for unrelated unruly behavior on the tarmac, though details remain limited.
The Federal Aviation Administration (FAA) confirmed the diversion was due to a passenger disturbance but provided no further details. The flight resumed its journey, arriving in Houston around 12:15 p.m. CT without further issues. “The safety of our passengers and crew are our top priority and we applaud the efforts of local law enforcement for their support,” All Nippon Airways said in a statement. Modern commercial aircraft, such as the Boeing 787-9 used for this flight, are engineered to prevent doors from being opened midflight. The cabin pressure at cruising altitude exerts a force that seals the doors shut, making physical attempts to open them virtually impossible.
Despite these safety features, attempts to tamper with emergency exits cause immediate concern due to the potential for panic or injury. Airline staff are trained to de-escalate such situations and follow strict procedures to ensure passenger safety.
An aviation safety expert noted, “Attempting to open an aircraft door midflight is practically impossible due to cabin pressure. Such incidents highlight the importance of crew vigilance and quick response to ensure safety.”
Flight diversions disrupt passengers and incur significant costs for airlines, including additional fuel, landing fees, crew overtime, and potential passenger compensation. Industry estimates suggest such events can cost tens of thousands of dollars per incident.
In this case, the diversion to Seattle likely resulted in logistical and financial challenges for ANA. The airline also had to coordinate with law enforcement and airport authorities to resolve the situation, adding to operational complexity. Such disruptions place strain on airline staff, who must balance safety protocols with customer service under high-stress conditions, underscoring the unpredictable nature of air travel.
The FAA reported 597 unruly passenger incidents in 2025 as of May 18, indicating a persistent challenge for the aviation industry. Long-haul travel, in particular, can exacerbate stress or underlying mental health issues, occasionally leading to disruptive behavior.
An aviation psychologist noted, “Passenger stress can escalate during long flights, sometimes leading to irrational behavior. Airlines must continue to invest in crew training to de-escalate situations and support passenger well-being.”
To address these challenges, many airlines have enhanced staff training, implemented stricter penalties for disruptive behavior, and improved pre-flight screening processes.
The FAA and international aviation authorities have clear guidelines for handling in-flight disturbances, including the authority to divert flights, detain individuals, and impose penalties. In the United States, interfering with a flight crew or tampering with aircraft systems can lead to federal charges, fines, or imprisonment.
In this incident, the passenger was not publicly identified, and no charges have been announced, likely due to the medical nature of the crisis. The swift response by law enforcement and the airline reflects adherence to safety protocols.
Airlines are exploring advanced surveillance systems and real-time communication tools to respond to potential threats more efficiently. The International Air Transport Association (IATA) advocates for global standards to address unruly passengers, aiming to enhance safety across the industry.
These developments represent a proactive approach to minimizing risk and ensuring the safety of all onboard.
The diversion of ANA Flight NH114 to Seattle following a passenger’s attempt to open an emergency exit midflight highlights the complexities of aviation safety and emergency response. Though the aircraft landed safely and no injuries were reported, the incident underscores the challenges airlines face in maintaining order at 35,000 feet.
As air travel continues to grow, the industry must invest in crew training, passenger support, and technological innovations to address emerging threats. Ensuring the well-being of passengers and staff remains critical to safe and reliable air travel.

FAQ
No. Due to cabin pressurization, it is physically impossible to open an aircraft door at cruising altitude. The pressure differential seals the doors shut.
The aircraft lands at the nearest suitable airport, where law enforcement and medical personnel respond. The disruptive passenger may be detained, evaluated, or charged.
Airlines use restraint, de-escalation techniques, and coordination with law enforcement. Passengers may face fines, bans, or criminal charges.
