New Southwest Airlines Rules for Lithium-Powered Mobility Devices

Beginning on September 25, 2025 Southwest Airlines will implement new regulations for passengers traveling with lithium-powered mobility devices. The new regulation requires customers to remove all lithium batteries from their wheelchairs or scooters before boarding the aircraft. The batteries will need to be carried aboard by passengers, but will not count towards their checked baggage allowance or personal items.

This change in policy is in the interest of safety. According to the airline, “Lithium batteries have become one of the most common sources of smoke and fire incidents on aircraft. While these events are rare, quick access and visibility are critical to keeping everyone onboard safe. By taking proactive steps now, Southwest will be among the first U.S. carriers to adopt these higher standards.”

Previously, mobility devices with lithium ion batteries were allowed to remain connected and be carried on the mobility device in the baggage compartment.

Additionally, the airline is instituting a new policy that will prohibit lithium ion batteries that are over 300 watt hours aboard the aircraft. To ease the transition, customers with batteries larger than 300 watt-hours will have a grace period through Jan. 11, 2026. After January  11, devices with batteries above the limit will no longer be accepted for transport. 

According to a statement by Southwest Airlines, “We recognize how important mobility devices are to many of our customers, and this update is designed to prioritize safety without creating unnecessary barriers to travel. While this change applies to less than 0.1% of our Customers, we remain committed to supporting each individual who may be affected.”

These policies are in line with federal regulation on the subject, as the FAA allows airlines to carry lithium-powered mobility devices; however it does not require them to do so. Individual airlines are also allowed to set their own policies for carrying lithium-powered mobility devices, as long as they meet the minimum safety standards set by the FAA. 

Look for more details to be released on this new policy in the coming days, but if you plan to travel with a lithium-powered mobility device on Southwest, it’s best to get to the airport early.
