The Transport Security Administration (TSA) is responsible for carrying out the U.S. government's laws on passenger and baggage screening for flights on all airlines in the United States. It screens checked baggage for a number of prohibited items, including some types of lighters. However, as of 2010, there are ways to pack lighters in checked luggage that adhere to TSA guidelines.
Torch lighters, a special type of lighter with a thin and intense flame, are not allowed in checked or carry-on luggage. These lighters provide a safety hazard because their flames can get to temperatures of more than 2500 degrees Fahrenheit, and the flame persists no matter what angle the lighter is held.
Lighters with fuel in them cannot be packed in checked luggage unless they are in a special type of case approved by the Department of Transportation. A number of companies sell these cases, each of which will hold up to two lighters.
The other way to pack lighters in checked luggage is for them to not have any fuel. Passengers on flights in the United States can pack as many lighters without fuel in their checked luggage as they would like.
Although lighters of all types were prohibited in carry-on baggage from March 31, 2005 through August 4, 2007, common lighters are now allowed in carry-on baggage. Torch lighters are still not allowed on airplanes.
