A Vietnam Airlines flight traveling from London Heathrow Airport to Hanoi was forced to make an emergency landing at Kolkata’s Netaji Subhas Chandra Bose International Airport after a Danish passenger experienced a serious medical emergency approximately nine hours into the flight. The flight, designated VN56, departed London on Sunday night local time and was en route to Hanoi when the passenger’s health suddenly deteriorated.
The cabin crew promptly administered first aid onboard, but the passenger’s condition did not improve, prompting the captain to make the critical decision to divert the flight. Prior to landing, the flight crew coordinated with Kolkata airport authorities to ensure medical teams were ready to provide immediate assistance upon arrival.
Once on the ground, the passenger was swiftly transported to a nearby hospital accompanied by two family members for further medical evaluation and treatment. The airline confirmed that the passenger’s condition was stable after transfer. After completing the necessary procedures and ensuring the passenger was in safe hands, flight VN56 resumed its journey to Hanoi at 3:43 p.m. local time on Monday, arriving approximately three hours behind schedule.
This incident is part of a recent pattern of Vietnam Airlines flights being diverted due to passenger health emergencies. Just days earlier, on June 30, flight VN7569 from Hanoi to Nha Trang was diverted to Da Nang due to a medical issue onboard. Earlier in June, on the 16th, flight VN158 from Da Nang to Hanoi made an emergency landing at Phu Bai Airport in Hue for similar reasons. Additionally, on May 5, 2025, flight VN35 from Hanoi to Frankfurt was diverted to Erzurum Airport in Turkey after a passenger required urgent medical attention.
Vietnam Airlines has reiterated the importance of passenger health awareness, advising travelers to consult with medical professionals before flying if they experience any unusual symptoms or have pre-existing health conditions that may be exacerbated by air travel. The airline also emphasized that flight crews are trained to handle medical emergencies and that safety remains their highest priority.
Medical emergencies in-flight pose significant challenges due to limited resources and the need for quick decision-making. Airlines worldwide have protocols in place to manage such situations, including coordinating with ground medical services and, when necessary, diverting flights to the nearest suitable airport. The recent series of diversions by Vietnam Airlines highlights both the unpredictability of medical emergencies and the airline’s commitment to passenger safety.
Passengers planning to travel long-haul or with known health issues are encouraged to carry relevant medical documentation, medications, and to inform airline staff of any special needs prior to boarding. This ensures timely and appropriate care can be provided if emergencies arise during the flight.
