If you pack a lighter in your checked suitcase in 2026, it will likely be detected and removed by airport security unless it meets very specific criteria. Per TSA and FAA regulations, disposable and Zippo lighters without fuel are allowed in checked bags, but fueled lighters are strictly prohibited unless they are enclosed in a specialized, Department of Transportation (DOT) approved case. If a prohibited fueled lighter or a "torch" (blue flame) lighter is found during the X-ray screening of your checked luggage, security personnel will open your bag, confiscate the item, and leave a notice of inspection behind. To avoid this, travelers are encouraged to keep their one permitted lighter on their person or in their carry-on bag. Lithium battery-powered lighters (plasma lighters) are also restricted to carry-on bags only and must have safety features to prevent accidental activation, as they pose a fire risk in the cargo hold.
