Either take a small bag full of lighters to check or just purchase a cheap bic when you arrive at your destination then.
Until now, if one wanted to legally transport a butane lighter, one either had to ship it via UPS ground, paying hazmat fees, or transport it on one's person. Now anyone seeking the latter course will have to take a bus, train, boat, or private conveyance.
Checking butane lighters was dangerous and illegal long before 9/11.
