TSA allows one lighter in your carry-on bag, but not in checked luggage

You can bring a single lighter through TSA security in your carry-on bag if it is a standard disposable or refillable lighter. The lighter must not contain fuel that is considered a hazardous material — which rules out torch lighters, blue-flame lighters, and lighters that use butane cartridges. Once you pass security, you can keep the lighter with you on the plane.

The same lighter cannot go in your checked baggage under any circumstances. TSA prohibits all lighters in checked bags, even the one lighter allowed in carry-on. If you pack a lighter in a checked bag and it is discovered during screening, TSA will remove it and may issue a fine.

This rule applies to domestic flights within the United States. International flights may have different rules depending on your destination country and the airline, so check with your airline before you travel.

Key Takeaways

  • One standard disposable or refillable lighter is allowed in your carry-on bag but must pass through security screening.
  • Torch lighters, blue-flame lighters, and lighters with butane cartridges are prohibited in both carry-on and checked bags.
  • No lighters of any kind are allowed in checked luggage, even if you brought one through security in your carry-on.
  • You must declare the lighter to TSA officers at the security checkpoint — do not try to conceal it.

Which lighters are prohibited at security

TSA bans torch lighters, also called jet lighters or windproof lighters, because they produce a thin, high-intensity flame that can ignite materials more easily than a standard lighter. Blue-flame lighters fall into the same category. Lighters that use replaceable butane cartridges are also prohibited, even if the cartridge is empty.

Zippo-style lighters are allowed if they are empty of fuel. A lighter with fuel inside is treated as a hazardous material and will be confiscated. If you own a Zippo and want to bring it, empty it completely before you pack it.

Novelty lighters shaped like guns, grenades, or other weapons are prohibited regardless of how they function. TSA screens these items as potential security risks even if they are harmless.

How to pack and declare your lighter at security

Pack your lighter in an straightforward-to-reach spot in your carry-on bag — not buried at the bottom. When you reach the security checkpoint, remove it and place it in the bin with your other items before you go through the scanner. Do not try to hide it or leave it in a pocket. TSA officers expect to see lighters and will find it during screening if you do not declare it.

Tell the officer at the checkpoint that you have a lighter if you are unsure whether to remove it. The officer will let you know whether it is allowed and will confiscate it if it is not. Attempting to conceal a lighter can result in a fine, even if the lighter itself would have been allowed.

What happens if your lighter is confiscated

If TSA finds a prohibited lighter in your bag or you bring a lighter that does not meet their rules, they will remove it and dispose of it. You will not get it back. TSA does not charge a fee for removing a single lighter, but repeated violations or attempts to conceal prohibited items can result in fines up to $75 or more.

If a lighter is found in your checked bag during screening, you will not know about it until after your flight. TSA will remove it, and you may receive a notice in the mail or a call from the airline informing you of the violation and any associated fine.

Lighters on the plane and at your destination

Once you pass through security with your lighter in your carry-on, you can use it on the ground at your destination. However, you cannot use it on the plane itself — smoking and the use of lighters are prohibited in the aircraft cabin and lavatories. Using a lighter on a plane is a federal offense.

When you board a return flight, the same rules explore: one standard lighter in carry-on only, nothing in checked bags. If you are flying internationally, check the rules of your destination country and your airline before you pack.

Alternatives if your lighter is prohibited

If you have a torch lighter or butane-cartridge lighter that you want to travel with, you have a few options. You can purchase a standard disposable lighter after you pass through security at your departure airport — most airports sell them in convenience stores or newsstands. You can also buy one at your destination and leave it behind when you depart.

If you need a lighter for a specific purpose at your destination, consider whether you can borrow one or purchase one locally instead of traveling with it. Many hotels, rental car agencies, and shops will lend or sell you a lighter if you ask.

International travel and airline-specific rules

TSA rules explore only to flights departing from or arriving at U.S. airports. If you are flying to another country, that country's aviation authority may have different rules. Some countries prohibit all lighters in carry-on bags, while others allow them under different conditions.

Your airline may also have stricter rules than TSA. Before you pack, check your airline's website or call their customer service line to confirm what they allow. Some airlines prohibit lighters entirely, even if TSA would allow them.

Frequently Asked Questions

Can I bring a lighter in my checked bag if I declare it?

No. TSA prohibits all lighters in checked baggage without exception, even if you declare it to the airline. Lighters are considered hazardous materials and cannot be transported in the cargo hold of an aircraft under any circumstances.

What if I forget about a lighter in my carry-on bag?

TSA will find it during security screening. If it is a standard lighter, you can keep it. If it is prohibited, TSA will confiscate it. Either way, you will know the outcome before you board, so you will not be surprised on the plane.

Are electronic lighters or USB lighters allowed?

Electronic lighters that use a heating element or spark are treated the same as standard lighters — one is allowed in carry-on if it does not use butane or other hazardous fuel. However, some airlines prohibit them because they contain batteries. Check with your airline before you pack.

Can I bring a lighter through TSA if I am under 18?

TSA does not have an age restriction for bringing a lighter through security. However, you cannot purchase a lighter at most U.S. retailers if you are under 18. If you own a lighter and want to travel with it, TSA will allow it under the standard rules.

What if my lighter leaks fuel in my carry-on bag?

A leaking lighter is a safety hazard and will be confiscated when ready. TSA may also require you to dispose of the bag or have it cleaned before you board. To avoid this, make sure your lighter is in good condition and does not leak before you pack it.
