In a bid to enhance safety on flights, Southwest Airlines has announced new regulations regarding the transport of lithium battery-powered portable chargers. Starting from April 20, passengers will be allowed to bring only one portable charger on board for personal use. This decision follows a concerning increase in incidents involving lithium batteries, which have included reports of smoke, fire, and extreme heat.
The Federal Aviation Administration (FAA) has reported a notable rise in verified incidents linked to lithium batteries. As of April 1, there have been 14 documented occurrences this year alone, reflecting broader trends that have seen a gradual increase in such incidents. In 2022, there were 95 confirmed cases in the United States involving overheating batteries, compared to 89 the previous year.
The new policy stipulates that portable chargers must be stored under the passenger’s seat or kept on their person while in the cabin. Storing these devices in overhead bins is strictly prohibited. Additionally, those travelling with such devices will not be able to recharge them using in-seat power outlets during their flight. This approach aims to minimise the risk of battery-related incidents occurring during the journey.
Dave Hunt, the Vice President of Safety and Security at Southwest Airlines, communicated these changes in an internal memo to employees, which was subsequently shared with the public. The memo mentioned that signage and updated announcements will be introduced to inform passengers about the forthcoming restrictions, ensuring that travellers are made aware prior to their departure.
As part of their long-term strategy, Southwest Airlines plans to enhance the availability of in-seat power across their fleet by mid-2027, which should reduce dependency on portable charging devices. Hunt emphasised the airline’s commitment to improving the in-flight experience while prioritising safety.
In recent years, Southwest Airlines has already established several safety measures regarding the use of portable batteries. Notably, the airline prohibited the charging of devices concealed in bags during flights in 2025. This initiative made Southwest Airlines the first major US airline to enact such restrictions, aiming to ensure that any overheating batteries can be swiftly addressed.
The rising incidence of battery-related incidents has prompted airlines worldwide to undertake preventive measures. The FAA has informed that thermal runaway, a process where a battery overheats uncontrollably, can cause serious safety risks. This phenomenon may occur due to various factors such as damage, overcharging, exposure to moisture, or even manufacturing defects.
The FAA and the Transportation Security Administration (TSA) already stipulate that lithium batteries must not be placed in checked luggage to mitigate the risk of potential fires in cargo holds. Given the recent trend of incidents, the new measures introduced by Southwest Airlines underscore an essential focus on onboard safety.
Passengers planning to fly with Southwest are urged to stay informed about the upcoming policy changes, which will be communicated via pre-trip notices, during check-in, and via electronic signage at airports. The emphasis on safer in-flight protocols intends to reassure travelers while maintaining accessibility to the necessary electronic items that are part of modern travel.
As the aviation industry continues to adapt to evolving safety challenges, Southwest Airlines remains proactive in addressing the risks associated with lithium battery use in-flight, ensuring the welfare of all passengers and crew members.
