I'm going on a trip this week, flying, and was wondering if I can fly with my lighter. I have a zippo with a Butane insert. Anybody fly with bics or Butane lighters? Have any problems? If you do fly with them did you put them in your checked bag or carryon? This is a sweet Peterson Zippo and I would hate to lose it. In the past I have just taken matches, but was considering the lighter.
