A passenger on a Cathay Pacific flight from Boston to Hong Kong was arrested after attempting to open an emergency exit during the flight. The incident occurred on an Airbus A350-1000 as the aircraft approached Hong Kong International Airport.
Police took the 20-year-old Chinese passport holder into custody upon the flight's arrival. Authorities are investigating the incident under Hong Kong's Aviation Security Ordinance.
Key Takeaways
- A passenger attempted to open an emergency exit on a Cathay Pacific flight.
- The incident happened during the approach to Hong Kong.
- Crew secured the situation, and no injuries were reported.
- The passenger faces charges under Hong Kong's Security Ordinance.

Incident Unfolds Aboard CX811
The flight, Cathay Pacific CX811, departed Boston Logan International Airport (BOS) on Thursday, December 11, nine minutes behind its scheduled 00:30 departure. The Airbus A350-1000 was on its way to Hong Kong, a journey that can take up to 15 hours.
During the flight's descent into Hong Kong, the passenger made an attempt to open one of the emergency exits. Cabin crew members responded quickly to the situation.
They attended to the passenger and immediately checked the emergency exit to ensure it remained securely closed. The crew then reported the incident to the relevant authorities on the ground.

Arrest Upon Arrival in Hong Kong
The aircraft landed safely at Hong Kong International Airport (HKG) at 04:32, ahead of its scheduled 05:00 arrival. Police officers met the plane at the gate.
The passenger was arrested on suspicion of violating Hong Kong's Security Ordinance. This ordinance makes it an offense to tamper with or interfere with any component, apparatus, equipment, or system on board an aircraft.
"The safety of its customers and crew comes first and guides every decision the airline makes," a Cathay Pacific spokesperson shared with NBC.
The airline confirmed that no passengers or crew members sustained injuries during the incident. The flight itself experienced no major disruptions and completed its journey as planned.
Aircraft Safety Features
It is important to understand that opening an emergency exit on an aircraft during flight at cruising altitude is nearly impossible. These doors are designed as 'plug doors.'
A plug door requires inward movement before it can be pushed outward. The significant pressure difference between the pressurized cabin and the lower external air pressure at high altitudes makes it physically impossible to pull the door inward.
If an emergency exit were to open mid-flight, it would cause a rapid depressurization of the cabin. This could lead to serious consequences, including the potential for unsecured objects or even people to be pulled out of the aircraft.
Consequences of Interference
Passengers who attempt to open an emergency exit during a flight often face severe legal repercussions. These can include arrest, federal charges for interfering with the aircraft and crew, and endangerment of others.
Such actions can also lead to placement on a no-fly list. In some cases, an aircraft might be forced to make an emergency diversion, incurring significant costs for the airline.
Cathay Pacific's A350 Fleet and Routes
Cathay Pacific operates a fleet of 18 Airbus A350-1000 aircraft, according to ch-aviation data. These aircraft are configured to carry 334 passengers, including 46 in business class, 32 in premium economy, and 256 in economy class.
The airline maintains several non-stop routes from the United States to Hong Kong International Airport. These include services from major cities such as Chicago (ORD), Dallas/Fort Worth (DFW), Los Angeles (LAX), New York (JFK), and San Francisco (SFO).
A new service from Seattle/Tacoma International Airport (SEA) is scheduled to begin on March 30, 2026. The incident underscores the importance of aviation security and passenger behavior on long-haul flights.
Previous Incidents
While rare, similar incidents have occurred globally. In 2023, a passenger on an Asiana Airlines flight opened a door during descent. This led to widespread panic, though the plane landed safely at Daegu International Airport (TAE).
Such events highlight the ongoing need for vigilance and adherence to safety protocols by both crew and passengers. Airlines prioritize the safety of everyone on board and train their staff to handle various in-flight emergencies.
