Southwest Airlines Imposes Restrictions on Certain Carry-On Items
Southwest Airlines has been at the center of recent discussions regarding carry-on item restrictions, specifically concerning lithium batteries. The airline implemented significant changes to its regulations that will affect travelers starting in April 2026.
Background on Lithium Battery Regulations
The prohibition on lithium batteries in checked luggage was first enforced in 2016. This ban came after several incidents of in-cabin fires linked to lithium-ion batteries. These batteries, which power various portable devices, contain volatile electrolytes that can ignite under certain conditions.
Southwest Airlines’ New Policy
In May 2025, Southwest Airlines became the first U.S. airline to require that portable chargers remain visible during flights. This means that passengers must keep these devices accessible, rather than stowing them deep within their bags.
New Limitations on Battery Packs
- One Charger Limit: As of April 20, 2026, each traveler is limited to one portable charger.
- No Charging on Board: Passengers will not be permitted to charge their power banks using seat outlets.
Previously, Southwest’s policy allowed travelers to carry up to 20 spare batteries. However, the latest updates have shifted the focus toward safety, urging passengers not to pack recalled or defective batteries due to fire hazards.
Global Regulations and Comparisons
In March 2026, the International Civil Aviation Organization (ICAO) mandated that travelers are limited to two batteries per person. This new global limit is part of a broader initiative to manage safety concerning lithium battery usage on flights.
Other major U.S. airlines, including United Airlines, Delta Air Lines, and American Airlines, have also revised their policies in accordance with ICAO guidelines. However, Southwest remains unique in enforcing stricter limits with its one-charger rule.
Guidelines from Other Airlines
- Delta Air Lines: Allows spare lithium batteries in carry-on baggage, provided they are protected to prevent short circuits.
- American Airlines: Similar policies to Delta, emphasizing accessible storage for spare batteries.
Recent Safety Concerns
Concerns about lithium batteries are backed by data from the Federal Aviation Administration (FAA), which recorded 97 fire incidents linked to these batteries in 2025, up from 89 in 2024. Such statistics highlight the ongoing importance of safety regulations in aviation.
In response, international carriers like Air New Zealand and Taiwan’s EVA Air have implemented stricter bans on various charging devices, including power banks and wireless headphones. These measures reflect a growing concern over the safety of electronic items on board.
