Following a lithium-battery laptop fire on an American Airlines flight that burned several passengers before crew doused it with a thermal containment bag, fire safety experts explain why such batteries must travel in carry-ons, not checked bags. The National Fire Protection Association cites a roughly 15% rise in battery-related airline incidents from 2024 to 2025, with power banks and vapes — often unlisted, meaning they don't meet U.S. safety standards — flagged as particular offenders.
Experts note even 'listed,' standards-compliant batteries in phones and laptops can still catch fire, as the American Airlines incident showed, when an internal separator is damaged by heat, cold, drops, or fast charging, triggering thermal runaway. Recommended precautions amount to buying from reputable retailers and keeping an eye on devices while they charge.
