Yes, you can fly with a standard Bic-style lighter, but there are strict rules about where you must keep it. According to 2026 TSA and international aviation regulations, you are permitted to carry one lighter on your person (in your pocket or held by hand). You are strictly prohibited from packing a lighter in your checked luggage, as the risk of accidental ignition in the cargo hold—where no one can see it or put out a fire—is considered a major safety hazard. Interestingly, while you can't put it in a checked bag, you are also technically not supposed to put it in your carry-on bag "loose"; it must be on your person at all times. Standard "disposable" lighters (like Bic) and refillable "Zippo" lighters (if the fluid is absorbed in the cotton) are generally allowed. However, "Torch Lighters" (the ones that produce a blue, wind-resistant flame) are strictly banned from both carry-on and checked luggage. If you are a smoker or need a lighter for camping, the standard "flick" Bic is your safest and only legal bet. Just remember that while you can carry it, you are never allowed to actually use it on the plane, and doing so will result in immediate federal intervention upon landing.
