A quick review of the link provided indicates that only 4 packages of book type, strike on cover type, or 2 non refill type butane lighters per person are permitted. It would appear that box type packages of matches and refillable type butane type lighters won't fly in carry on luggage or clothihng. All that said, it also stated that the screeners clearly have the option of making on the spot decisions to deny items they are deem inappropriate.

edit: Looks like Jet & I both posted regarding the same concerns at the same time: <img src="images/graemlins/laugh.gif" alt="" />
