A 34-year-old female passenger died mid-flight aboard a KLM Boeing 787-10 Dreamliner traveling from Amsterdam to Los Angeles, forcing the aircraft to make an unscheduled diversion to Yellowknife Airport in Canada’s Northwest Territories, according to aviation and law enforcement reports.
Flight Diversion and Emergency Response in Yellowknife
The aircraft, operating as flight KL601, departed Schiphol Airport in Amsterdam at 10:15 a.m. CEST on Sunday, October 5, 2025, according to flight data cited by Daily Mail. Roughly halfway across the North American Arctic, cabin crew members discovered the passenger was unresponsive and initiated first aid alongside medical professionals traveling onboard, as reported by Aviation A2Z.
The flight crew declared a medical emergency and routed the widebody jet toward Yellowknife Airport, where it touched down safely at approximately 9:35 a.m. MT on Sunday. Emergency responders, including personnel from the Royal Canadian Mounted Police (RCMP), met the aircraft on the tarmac. Paramedics rushed the passenger to a local hospital, where she was pronounced dead despite ongoing resuscitation efforts.
Investigation and Airline Protocol
Local authorities confirmed that the incident remains under active investigation. According to statements from the RCMP provided to Daily Mail, the Mounties are partnering with the local Coroner’s Service to determine the exact circumstances of the death. Officials have withheld the passenger’s identity pending family notification.
KLM representatives stated that the flight crew followed all standard in-flight emergency procedures with professionalism and care. Under guidelines outlined by the International Air Transport Association (IATA) and noted by Aviation A2Z, commercial flight attendants receive extensive training to manage medical crises at altitude, performing cardiopulmonary resuscitation and utilizing onboard automated external defibrillators until the aircraft can land or professional help takes over. After remaining on the ground in Yellowknife for several hours, the KLM Dreamliner resumed its journey to Los Angeles International Airport.
