Southwest Airlines is implementing a new safety policy, effective May 28, requiring passengers to keep portable phone chargers and power banks visible during flights when you’re charging a device. The airline will prohibit the use of these devices while they’re stored in carry-on bags or overhead bins, aiming to mitigate the risk of lithium-ion battery fires.
This policy change comes in response to a series of incidents involving overheating lithium-ion batteries. According to the Federal Aviation Administration, there have been 22 battery-related incidents on flights in 2025 alone, following a record 89 such events in 2024. Notably, a fire aboard an Air Busan flight in South Korea in January — suspected to have been caused by a power bank with deteriorated insulation — led to the evacuation of 176 people, including passengers and crew.

While the FAA and the Transportation Security Administration currently allow lithium-powered devices, like e-cigarettes and power banks, in carry-on luggage but prohibit them in checked bags, they do not mandate that portable chargers be kept in plain sight. Southwest’s new policy goes a step further, aligning with practices already adopted by some Asia-based carriers, including Singapore Airlines, AirAsia and all South Korean airlines, according to Reuters.
This move by Southwest Airlines reflects a growing concern in the aviation industry regarding the safe transport and use of lithium-ion batteries on aircraft. Passengers are encouraged to stay informed about airline policies and to handle electronic devices with care to ensure a safe travel experience.
“Southwest will introduce a first-in-industry safety policy on May 28 requiring customers to keep portable charging devices visible while in use during flight,” Southwest Airlines confirmed in a statement to CNET via email. “Using portable charging devices while stored in a bag or overhead bin will no longer be permitted. Nothing is more important to Southwest than the safety of its customers and employees.”
