As of Thursday, April 14, TSA screeners will now be enforcing this rule at security checkpoints. Lighters will no longer be allowed in carry-on luggage or on the person. As always, ALL lighters are banned from checked baggage for safety reasons.
TSA strongly recommends that you double-check your baggage and pockets for lighters before arriving at the airport. Because of federal laws and operational considerations, TSA cannot return any prohibited items voluntarily abandoned at the checkpoint.
