Can You Bring a Gun on a Plane?

Firearms are banned from carry-on luggage worldwide — this is a universal rule with no exceptions. In the United States, firearms may be transported in checked luggage under strict rules. International travel with firearms is extremely complex and often prohibited entirely.

Carry-On: Absolutely Prohibited

No country permits firearms in carry-on baggage on commercial flights. This applies to:

• Handguns, pistols, revolvers
• Rifles, shotguns, carbines
• Pellet guns, BB guns, airsoft guns
• Replica and imitation firearms (including those that cannot fire)
• Flare guns and starter pistols
• Stun guns and tasers (also banned from carry-on)
• Firearm parts (barrel, slide, frame, magazine)

There is no minimum caliber, no unloaded exception, and no case-type exception for carry-on. If a firearm or firearm component is found during security screening, the passenger is stopped, law enforcement is called, and criminal proceedings may follow.

Checked Luggage in the United States

The TSA permits passengers to check firearms on US domestic flights and US international departures, subject to strict requirements:

The Requirements

1. Unloaded — the firearm must be completely unloaded. No round in the chamber, no live ammunition in the magazine, no magazine in the weapon
2. Hard-sided locked case — the firearm must be in a hard-sided container (not a soft bag) that the passenger locks. TSA-approved locks are recommended so TSA can inspect the case if needed without damaging the lock
3. Declared at check-in — you must tell the airline agent at the check-in counter that you are checking a firearm. You cannot use a kiosk or self-service bag drop for a bag containing a firearm
4. Firearms declaration card — the airline provides a paper card that you sign and place inside the locked case, visible inside when opened
5. Checked bag only — the case must be checked to the hold. It cannot travel as a gate-checked item

Ammunition Rules

• Ammunition must also travel in checked luggage — not carry-on
• Limit: 11 lbs (5 kg) of small arms ammunition per passenger
• Ammunition must be in its original factory packaging or a container specifically designed for ammunition storage
• Loose rounds, rounds in a shoebox, or rounds mixed with other items are not permitted
• Ammunition cannot be in the same locked case as the firearm, according to most airline policies (check with your specific carrier — policies vary)

Airline Policies

Airlines impose their own rules on top of TSA rules. Common variations:

• Maximum number of firearms per bag or per booking
• Whether ammunition can be in the same case as the firearm
• Additional fees for checking a firearm
• Specific case requirements beyond TSA minimums

Always confirm your airline's firearms policy before travel — it is different from the TSA rules and stricter at some carriers.

International Travel with Firearms

Travelling internationally with a firearm is substantially more complex and in most cases not practical for civilian travelers.

• Import laws vary enormously — many countries prohibit civilian import of firearms entirely, regardless of how they are packed
• Export permits — the US requires export documentation for firearms leaving the country (State Department or Commerce Department, depending on the firearm type)
• Transit countries — stopping in a country en route can create import/export obligations even if you do not leave the airport
• Criminal penalties — importing a firearm without authorization is a serious criminal offense in most countries, including popular travel destinations in Europe, Asia, and Latin America

If you are a competitive shooter or hunter traveling internationally with firearms, engage a specialist customs broker or contact the embassy of each country on your itinerary months before travel.

Replicas, Airsoft, BB Guns, and Pellet Guns

For aviation purposes, all of the following are treated identically to real firearms:

• Airsoft guns (even if obviously plastic)
• BB guns and pellet guns
• Replica pistols and rifles
• Starter pistols
• Cap guns that are realistic replicas

They must be declared at check-in and packed in checked luggage under the same rules as live firearms. An airsoft gun found in carry-on will trigger the same security response as a real weapon.

Consequences of Non-Compliance

The TSA imposes civil penalties for undeclared firearms found at security checkpoints:

• First violation: up to several thousand dollars per firearm
• The specific amount depends on whether the firearm was loaded, the passenger's intent, and other factors
• Criminal charges under federal law are possible for knowingly attempting to carry a firearm onto an aircraft

In 2025, the TSA reported discovering thousands of firearms at checkpoints across the US — the majority carried inadvertently in bags that had previously been used for range trips. Before any flight, check every bag and every pocket, including range bags, backpacks, and luggage that has been stored.
