In a decisive move aimed at enhancing passenger safety, Southwest Airlines has announced a new policy limiting the number of portable battery chargers allowed on board its flights. Starting April 20, travellers will be restricted to a single charger, which must remain visible during the flight. This measure is a response to rising concerns over the fire hazards associated with lithium batteries, a risk that has increasingly troubled airlines globally.
New Restrictions Come into Effect
Effective from April 20, passengers will only be permitted to bring one portable charger aboard Southwest Airlines flights. The airline has made it clear that these devices cannot be stowed in overhead compartments and cannot be recharged using the aircraft’s power outlets. This new regulation builds on existing guidelines that require passengers to keep chargers accessible, allowing crew members to respond swiftly in the event of overheating incidents.
Lithium batteries are known for their potential to ignite and produce hazardous fumes, particularly perilous in the confined space of an aircraft. The U.S. Fire Administration has highlighted that these devices can not only catch fire but may also re-ignite after being extinguished. In line with these dangers, the International Civil Aviation Organization had previously recommended that airlines permit only two chargers per passenger. Southwest’s approach goes a step further in an effort to mitigate risks.
Growing Concerns Over Lithium Battery Incidents
The decision to tighten restrictions follows a troubling increase in reported incidents involving lithium batteries. According to the Federal Aviation Administration (FAA), the number of these incidents has risen annually, with 97 cases documented in 2025 alone. Jeff Marootian, CEO of UL Standards & Engagement, noted that his organisation is alerted to roughly two lithium battery incidents each week, reflecting a staggering 42 per cent increase over the previous year.
Such incidents are not merely statistics; they manifest in dramatic airline emergencies. In January 2025, an Air Busan flight in South Korea was forced to evacuate all 176 passengers after a power bank ignited, damaging the aircraft’s structure. Similarly, an Alaska Airlines flight had to return mid-air when a charger overheated, requiring the crew to extinguish the flames using fire safety equipment.
Southwest’s Response and Future Plans
In light of these risks, Southwest Airlines has affirmed its commitment to passenger safety. Dave Hunt, the airline’s Vice President of Safety and Security, stated that the carrier does not intend to search bags or confiscate chargers but will increase awareness about the potential dangers associated with lithium batteries. Passengers will be educated on these risks during the booking process and upon arriving at the airport.
To further alleviate concerns regarding device charging during flights, Southwest has announced plans to equip its entire fleet with in-seat power outlets by mid-2027. Hunt expressed optimism about this enhancement, stating, “Access to onboard power will continue to expand. By mid-year 2027, our entire fleet will feature in-seat power, reducing reliance on portable chargers and supporting a more consistent, convenient inflight experience.”
Why it Matters
These new restrictions reflect a growing recognition of the hazards posed by lithium batteries in the aviation industry. As air travel continues to recover from the pandemic, the safety of passengers remains paramount. The steps taken by Southwest Airlines not only aim to protect those on board but also signal a broader trend within the airline industry towards stricter regulations concerning battery-operated devices. As the potential for catastrophic incidents looms, proactive measures like these are crucial for ensuring that air travel remains as safe as possible.
