A KLM Boeing 777-300ER was forced to return to Amsterdam after a power bank caught fire during a flight over the Atlantic Ocean, highlighting once again the potential dangers of lithium-ion batteries on aircraft.
The incident occurred on KLM Flight KL735, which was traveling from Amsterdam Schiphol Airport to Curaçao on September 17, 2026. The aircraft was carrying around 322 passengers when the problem occurred during the flight.
According to reports, a power bank in the Business Class cabin overheated and suddenly caught fire with a loud bang. The fire caused smoke and visible damage around the passenger seat, window area and nearby cabin surfaces.
Cabin crew members reacted quickly and managed to extinguish the fire and secure the device. Although the immediate fire was brought under control, the pilots decided that the safest option was to turn the Boeing 777 around and return to Amsterdam.
The aircraft eventually landed safely at Schiphol after several hours in the air. Passengers were then rebooked onto another flight to continue their journey to Curaçao.
Dutch media reported that the power bank was allegedly connected to former KLM CEO Camiel Eurlings. However, KLM has not officially confirmed the passenger’s identity, citing privacy considerations. Reports also stated that the passenger suffered minor injuries.
KLM has strict rules regarding power banks. Passengers may carry permitted power banks in their hand luggage, but the airline prohibits passengers from using or charging them during the flight. The devices must also remain accessible rather than being stored in overhead compartments.
The incident is another reminder of the risks associated with damaged or overheating lithium-ion batteries. When a battery experiences a serious failure, it can rapidly generate heat and potentially produce smoke or flames.
For passengers, the key message is simple: follow airline instructions for power banks and portable batteries. A small electronic device can become a serious safety issue when it overheats inside an aircraft cabin.
The KLM incident is now being investigated, while passengers affected by the diversion were provided with alternative travel arrangements.
