A Vietnam Airlines flight from Hanoi to Singapore was forced to return to Noi Bai International Airport on October 19, 2025, after a passenger suffered a medical emergency shortly after takeoff. The flight, VN661, was bound for Singapore’s Changi Airport with local and international passengers onboard.
Passenger Suffers Seizure Mid-Flight
Reports confirmed that a 52-year-old Filipino passenger experienced a seizure and lost consciousness during the early stage of the journey. The cabin crew immediately called for medical assistance from passengers and administered first aid along with oxygen support.
Emergency Landing in Hanoi
Despite the crew’s quick response, the passenger’s condition remained critical. The pilot decided to turn the aircraft back to Hanoi, alerting air traffic control about the emergency. Medical teams were ready on the ground when the plane landed.
Immediate Medical Response Ensured
After landing, the passenger was transferred to a nearby hospital for treatment. The aircraft was inspected and cleared to resume its flight to Singapore later the same day after medical authorities confirmed the situation was under control.
Vietnam Airlines Issues Statement
Vietnam Airlines released an official statement confirming that the decision to return was made to prioritise passenger safety. The airline commended its crew for handling the medical emergency efficiently and following all safety protocols.
Other Recent Flight Disruptions
The airline also mentioned it had recently faced a 14-hour delay earlier in October on another Singapore–Hanoi route due to logistical challenges at Changi Airport. However, officials clarified that this Hanoi–Singapore diversion was solely due to a medical emergency.
Crew’s Quick Action Praised
The coordinated efforts of the cabin crew, pilots, and emergency responders helped ensure immediate care for the passenger. The incident highlights Vietnam Airlines’ preparedness and the efficiency of its medical emergency procedures.
