Just to make a correction, you cannot carry any lighter with you on carry-on luggage. You may only carry up to two Zippo (not butane) lighters in DOT approved cases in your checked luggage. For reference to these rules about lighters and matches, see http://www.tsa.gov/travelers/airtravel/assistant/editorial_multi_image_with_table_0099.shtm. For the full list of permitted and prohibited items, see http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm.
