How to Fly With a Firearm: TSA Rules, Packing & Airline Policies

How to Fly With a Gun: Step by Step

 

Here’s the whole process, start to finish. Follow these five steps and you’ll move through check-in smoothly.

1. Pack it in checked baggage — not your carry-on. A firearm can never go through the security checkpoint or into the cabin. It travels in a bag you check at the counter.
2. Unload the firearm completely. No round in the chamber, no loaded magazine inserted. The TSA considers a firearm “loaded” whenever the gun and its ammunition are both accessible together.
3. Lock it in a hard-sided case. Use a rigid, hard-sided container that fully secures the firearm, and lock it so that only you hold the key or combination. If a case can be pried open at a corner, it doesn’t qualify — TSA agents look for a container the firearm is “totally inaccessible” inside.
4. Declare it at check-in. Tell the airline agent you’re traveling with an unloaded firearm. You’ll typically sign a declaration card that goes inside the case. This step is not optional — an undeclared firearm is where travelers get into real trouble.
5. Pack your ammunition correctly. Ammo goes in checked baggage too, in packaging designed to hold it securely (see the ammunition section below).

The TSA Rules, Explained

 

The Transportation Security Administration (TSA) sets the federal baseline that applies at every U.S. airport, on every airline. Here’s what it requires:

• Checked baggage only. Firearms and firearm parts must be unloaded, locked in a hard-sided container, and transported in checked baggage.
• You keep the key. The case must be locked, and only you — the passenger — may retain the key or combination.
• Declare at the counter. All firearms (and certain firearm parts) must be declared to the airline at the ticket counter during check-in.
• Magazines and clips count. Loaded or empty, magazines and ammunition clips must be securely boxed or packed inside the hard-sided case with the unloaded firearm.

For the full federal rules, see the TSA’s firearms and ammunition page. When your state or airline rule is stricter than the TSA’s, the stricter rule wins — so read both.

 

 

 

Ammunition Rules & Packing

 

Ammunition travels in checked baggage, never in the cabin. Pack it in the original box or in a fiber, wood, or metal container specifically made to hold ammunition securely.

• Caliber limit. Small-arms ammunition — up to .75 caliber for rifles and pistols, and shotgun shells of any gauge — may be carried in the same hard-sided case as the firearm.
• Weight limit. The TSA doesn’t set a weight limit, but most airlines cap ammunition at 11 lbs (5 kg) per passenger. A few carriers allow more — always confirm with yours.
• Keep it contained. Loose rounds are a no. Rounds must stay in packaging designed to separate and protect them.

Storing ammo safely matters at home, too. See our guide on the best way to store ammo.

 

 

 

Airline-by-Airline Firearm Policies

 

Every U.S. airline follows the same TSA baseline — checked baggage only, unloaded, locked hard-sided case, declared at check-in. Where they differ is in the details: ammunition limits, fees, international restrictions, and a few carrier-specific quirks. Here’s a snapshot of the major carriers.

 

 

 

Flying American Airlines with a firearm

 

American accepts firearms in checked baggage when they’re unloaded and locked in a hard-sided case where the firearm is totally inaccessible (rifle cases need a lock on each end). Ammunition is capped at 11 lbs (5 kg) per person and must be in fiber, wood, or metal packaging. There’s no dedicated firearm fee, though standard checked-bag and oversize/overweight charges can apply.

 

Flying Southwest with a firearm

 

Southwest follows the TSA baseline: declare at the counter, unloaded, locked hard-sided case, ammunition in checked baggage. Southwest also publishes separate guidance for airsoft and paintball markers, which are treated differently from firearms.

International & Connecting Flights

 

Flying abroad adds a second rulebook. Beyond TSA and airline rules, your destination country — and any country you connect through — may require import permits, prohibit certain firearms outright, or ban ammunition. Some U.S. carriers (like Frontier and JetBlue) don’t allow firearms on international routes at all.

 

Before any international trip, confirm the firearm and ammunition rules for your destination and every connecting country, and build in extra time for customs. When in doubt, contact the airline and the destination’s consulate directly.

 

What Happens If You Break the Rules

The most common — and most expensive — mistake is bringing a firearm to the security checkpoint, or failing to declare one you’ve checked. Both can trigger TSA civil penalties that reach into the thousands of dollars per violation, and can cost you TSA PreCheck eligibility. Depending on the airport, local law enforcement may also get involved, and state or local laws still apply the moment you land.

 

 

Frequently Asked Questions

 

Can I fly with a gun?

 

Yes. You can fly with an unloaded firearm in checked baggage, locked in a hard-sided case, as long as you declare it to your airline at check-in. Firearms are never allowed in carry-on bags or the cabin.

 

Can I keep ammunition in the same case as my firearm?

 

In most cases, yes. The TSA allows small-arms ammunition (up to .75 caliber and shotgun shells of any gauge) in the same hard-sided case as the unloaded firearm, as long as it’s in proper packaging. Some airlines prefer it separated — check yours.

 

Do I have to declare an unloaded firearm?

 

Always. Even unloaded, every firearm must be declared to the airline agent at check-in. Skipping this step is what turns a routine trip into a fine.

 

Can I fly with a handgun and a rifle?

 

Yes. Both are allowed in checked baggage under the same rules — unloaded, in a locked hard-sided case, and declared. Long-gun cases often require a lock on each end.

 

What happens if TSA finds an undeclared firearm?

 

Bringing a firearm to the checkpoint or failing to declare a checked one can lead to TSA civil penalties, loss of PreCheck, and possible involvement from local law enforcement. Declare early and you avoid all of it.

 

Can I fly with a gun to a state where I don’t have a permit?

 

Checked-baggage transport is governed by federal TSA rules, but the laws of your destination still apply once you land — including how you may store, transport, or carry the firearm there. Research your destination’s laws before you go, and see our concealed carry reciprocity map for how permits travel.

 

The Bottom Line

 

Flying with a firearm is straightforward once you know the routine: check it, unload it, lock it, declare it, and pack your ammunition right. Confirm your airline’s specifics ahead of time, give yourself a few extra minutes at the counter, and you’ll be on your way. Travel prepared — and travel protected.
