The New York Times (free registration) reports in their piece, "The Team From Zippo Goes to Washington" that:
"It's now O.K. to pack unfueled lighters, which had been prohibited from all bags in April. The latest change is described on the Transportation Security Administration's Web site, where the revised list of 'Permitted and Prohibited Items' can be found. While it is still forbidden to take a lighter in a carry-on bag, 'lighters without fuel are permitted in checked bags, but lighters with fuel are prohibited,' the revised list says."
The TSA site has a lot of useful information for air travelers, including "Security Checkpoint Wait Times" and "Am I wearing the right shoes?"
Prohibited items are generally defined as "...weapons, explosives, incendiaries, and include items that are seemingly harmless but may be used as weapons - the so-called 'dual use' items. You may not bring these items to security checkpoints without authorization."
Before taking a flight, you should review the
Permitted and Prohibited Items list, which details what is allowable or not on carry-on and checked baggage. Some previously unallowable items are now allowed, like nail files and tweezers. My favorite allowable is "toy transformer robots." Carry-on unallowables (but allowable checked) include meat cleavers, pointed metal scissors, and spear guns. Gun powder you can't carry or check (duh), and hand grenades are specifically excluded.
The list also provides some information about your criminal liability and what the screener can do or consider. You'd be wise to review that before starting an argument over the allowability of an item as you stand at the security point.
Back to lighters, the Times article says,
"The revised list doesn't specify this, but it's now also O.K. to pack two Zippo-brand lighters, fueled, in your checked bags, if they're in a certified vaporproof case."
I don't see that on the TSA site, and I'm not sure what their source is.
Addendum: Strike that last sentence. I contacted the author at the New York Times asking about the source, and I learned that I did a poor job of reading the article. Here's what it says:
"On June 23, the Transportation Department granted an 'emergency exemption' specifically for Zippo, allowing passengers to pack two fueled Zippo lighters in the new, certified, vapor tight Otter cases."
The
Zippo site has a
Zippo Cargo Case link where you learn all about the case and order one.
Otter Box actually makes a very nice line of boxes (for
PDAs,
iPods, and cigars) and
cases (for larger valuables) that are waterproof, crushproof, and they float.
