FYI, you can take bic lighters on airplanes. It can't be checked but you can take it along as carry on. Put it into the quart bag of liquids. The only thing that you can't take on an airplane is cooking fuel, unless you cook with drinkable spirits. But that would get expensive due to liquor tax.

That's the only time I'm glad for smokers, they enable me to take lighters along in an airplane. So thank you for smoking.
