Lithium Batteries on Flights: What You Need to Know Before Traveling

Lithium batteries have long been a concern in air travel safety due to their potential fire risk. According to the U.S. Federal Aviation Administration (FAA), incidents involving overheating lithium batteries were reported every two weeks in 2024, a significant increase compared to 2018. In response to this growing risk, many airlines have updated their policies regarding the transportation and use of these devices on board.

Why Are Lithium Batteries a Risk on Flights?

Lithium batteries are found in a wide range of electronic devices, from mobile phones to laptops and power banks. However, their chemical composition makes them prone to overheating and, in some cases, spontaneous fires caused by short circuits or manufacturing defects.

In a pressurized cabin, a fire caused by a lithium battery could spread rapidly, endangering passengers and crew. For this reason, most airlines and aviation safety authorities have implemented strict regulations to minimize these risks.
