Flammables

Measures must be taken to prevent unintentional activation of the heating element while on board the aircraft. Examples of effective measures to prevent unintentional activation include, but are not limited to: removing the battery from the lighter; placing the lighter into a protective case; and/or using a protective cover, safety latch, or locking device on the lighter's activation button.

Each lithium ion battery must not exceed a Watt-hour (Wh) rating of 100 Wh; or for lithium metal batteries, a lithium content of 2 grams.

Recharging of the devices and/or the batteries on board the aircraft is not permitted.

See FAA regulations for more information.

Disposable and Zippo lighters without fuel are allowed in checked bags. Lighters with fuel are prohibited in checked bags, unless they adhere to the Department of Transportation exemption, which allows up to two fueled lighters if properly enclosed in a DOT approved case.

Torch lighters create a thin, needle-like flame that is hotter (reaching 2,500 F) and more intense than those from common lighters. Torch lighters are often used for pipes and cigars, and maintain a consistent stream of air-propelled fire regardless of the angle at which it is held.
