Amsterdam, Netherlands – A KLM Royal Dutch Airlines flight from São Paulo, Brazil, experienced a mid-air incident Tuesday night when a portable phone charger ignited, prompting a swift response from the crew and raising renewed concerns about the safety of lithium-ion batteries on aircraft.
Passengers aboard flight KL789,a Boeing 777-300ER,were observed covering their faces as a flight attendant utilized a fire extinguisher to contain the blaze,which originated from a passenger’s power bank. The incident occurred approximately six hours into the roughly 11-hour journey to Amsterdam Schiphol Airport (AMS).
“Smoke was detected on board due to a burning power bank,” KLM stated in a press release. “The crew quickly extinguished the device, following established safety procedures.” The flight landed safely at AMS at 14:35 CET on Wednesday, and no injuries were reported among the 282 passengers and 18 crew members.
Power banks, commonly used to recharge electronic devices on the go, rely on lithium-ion batteries. While permitted in carry-on luggage, thes batteries are strictly prohibited in checked baggage due to the risk of thermal runaway – a chain reaction leading to overheating and potential fire. The U.S. Transportation Security Administration (TSA) provides detailed guidelines on traveling with these devices: https://www.tsa.gov/travel/security-screening/whatcanibring/items/power-banks.
This incident follows a similar event in December 2023, when a delta Air Lines flight from Fort Myers, Florida, was forced to make an emergency landing after a portable battery ignited. The FAA has reported a dramatic increase in lithium battery-related incidents. Data released in December 2024 revealed a 388% surge in lithium battery fires on U.S. flights since 2015, averaging almost two incidents per week. These batteries are ubiquitous, powering not only portable chargers but also laptops, tablets, cameras, smartwatches, and e-cigarettes.
The growing concern is reflected in a recent survey by UL Standards & Engagement, a safety research organization. The survey, encompassing over 800 flight attendants, found that 87% expressed worry about the risks posed by lithium batteries during flights. Alarmingly, the survey also indicated that 25% of passengers admit to improperly packing lithium batteries in their checked luggage, a direct violation of safety regulations.
Experts emphasize the importance of adhering to airline and TSA guidelines regarding lithium battery transport. Proper packaging, avoiding damage to the batteries, and carrying them in carry-on luggage are crucial steps to mitigate the risk of fire. The FAA is currently evaluating potential new regulations to address the escalating threat, including stricter packaging requirements and enhanced passenger education.
