Lighters, Nail Clippers and Lithium Batteries
Just wanted to jump in with a quick post based on some of the comments
we’ve received so far about lighters, nail clippers and batteries. We
just wanted to let you know that lighters and nail clippers are allowed
through the checkpoint. Lighters were allowed starting in July 2007, and
nail clippers, as well as smaller scissors and tools, have been allowed
through the checkpoint since December 2005. Unlike improvised explosives
devices (IEDs), these items do not present a significant threat to an
airplane.
