I'm one of those dinosaurs that still smoke. I've never had a problem carrying a lighter or small/moderate folding knife aboard commercial airliners. Caveat - I have only flown domestic, but I hear our security is tighter than most. But then again, once I carried a loaded .22 magazine in my carry bag on a round trip, didn't know I had it until I unpacked at home. I guess sometimes they just aren't paying attention to the x-ray machine. DON'T TRY THIS unless you look good in steel bracelets.<br><br>a prodigal scout, just trying to be prepared.
