Can You Fly With Ammo? TSA Rules for Ammunition in 2026

TSA Rules: The Basics

The TSA permits ammunition in checked baggage under these conditions:

Checked bags only. Ammunition is never allowed in carry-on bags, your pockets, or on your person. It must go in the same checked suitcase as (or separate from) your declared firearm. Loose rounds in a carry-on will result in confiscation and potentially a fine.

Original packaging or ammo container. Ammo must be packed in the manufacturer's original box, or in a container specifically designed to hold ammunition (ammo cans, plastic ammo boxes, cartridge holders). The container must securely hold the rounds and prevent movement. You cannot throw loose rounds in a Ziploc bag or dump them in your suitcase pocket.

Loaded magazines are allowed — but they must be completely enclosed in a box or container that prevents accidental contact with the cartridge primer or trigger mechanism. A loaded magazine in a Kydex mag carrier inside an ammo can is fine. A loaded magazine loose in your bag is not.

Ammunition cannot be in the same container as a firearm unless the firearm is unloaded and in a locked, hard-sided case. In practice, most travelers put ammo in its original box inside the same locked case as the unloaded firearm. This is legal and is the most common method.

The 11-Pound Weight Limit

Most major airlines cap ammunition at 11 lbs (5 kg) gross weight per passenger. This limit comes from IATA (International Air Transport Association) Dangerous Goods Regulations and has been adopted as policy by Delta, United, American, Southwest, JetBlue, and most other U.S. carriers.

How many rounds can you fit in 11 lbs? More than most people expect:

The weight includes the container. If your ammo box weighs 8 oz, that counts toward your 11 lbs. Plan accordingly.

Step-by-Step: How to Fly With Ammo

Step 1: Check Your Airline's Specific Policy

While most airlines follow the 11-lb IATA standard, policies vary on details. Some airlines require ammo to be in a separate bag from the firearm. Some want the ammo in the original manufacturer's packaging specifically (not just any ammo can). Check your airline's firearms/ammunition policy page the day before your flight — policies can change.

Step 2: Pack Properly

Keep ammo in original boxes whenever possible. If you're using a reusable ammo can or plastic case, make sure rounds are held securely and can't shift or tumble. The TSA agent will inspect the container — if rounds are loose, they may reject it.

Step 3: Declare at Check-In

Tell the airline agent at the check-in counter that you're checking ammunition (and a firearm, if applicable). They'll give you a declaration tag to place inside the case. Some airlines require you to fill out a form. This is not optional — failing to declare ammunition is a federal offense.

Step 4: TSA Inspection

After you declare, the bag goes through TSA screening. In some airports, they'll ask you to open the case for visual inspection at the counter. In others, it goes through the X-ray machine normally. Either way, have your key or combination ready.

Step 5: Pick Up at Destination

Your checked bag with ammunition arrives at the normal baggage carousel. In some airports, oversized or declared-firearm bags go to a separate pickup area (often the oversized luggage counter). Ask at the gate if you're unsure.

The FOPA Trap: Flight Diversions and Layovers

The Firearm Owners Protection Act (FOPA), 18 U.S.C. § 926A, provides "safe passage" for transporting firearms and ammunition through states where they might otherwise be illegal. It protects you when driving through a restrictive state, as long as the firearm is unloaded and not readily accessible.

But FOPA has critical limitations when flying:

FOPA is an affirmative defense, not immunity from arrest. This means if you're arrested in New York City with ammunition in your checked bag after a flight diversion, FOPA doesn't prevent your arrest — it gives your lawyer something to argue in court. You may still be handcuffed, booked, and spend a night in jail before a judge hears your case.

FOPA only protects continuous transport. If your flight is canceled or diverted to Newark (New Jersey) or LaGuardia/JFK (New York City) and you take possession of your checked bag, you are now "in possession" of ammunition in a jurisdiction where certain ammunition types are restricted. New Jersey's hollow point law (N.J.S.A. 2C:39-3(f)) penalizes possession with up to 18 months imprisonment and $10,000 fine per cartridge.

State-Specific Complications

Federal TSA rules are the same everywhere, but state laws at your origin and destination can create problems:

International Travel

Flying internationally with ammunition adds an entirely different layer of complexity. Most countries restrict or prohibit civilian ammunition import. If you're traveling for a hunting trip or competition, you'll typically need an import permit from the destination country, documentation of the sporting purpose, and advance coordination with the airline's international firearms desk. This article covers U.S. domestic travel only — for international trips, contact both your airline and the destination country's embassy well in advance.

Common Questions

Can I fly with reloaded ammo?

Technically yes — the TSA doesn't distinguish between factory and reloaded ammunition. However, some airlines specify "commercially manufactured ammunition" in their policies. If you're flying with reloads, put them in a commercial ammo box and be prepared for questions.

Can ammo go in my carry-on if it's in a locked container?

No. Never. Ammunition is prohibited in carry-on bags regardless of packaging. This is a hard TSA rule with no exceptions.

Do I need to be 21 to fly with ammo?

Federal law sets the minimum age at 18 for long gun ammunition and 21 for handgun ammunition. Airlines may have their own age policies. Check with your carrier.

What about shotgun shells?

Same rules apply. Shotgun shells are ammunition. Pack them in original packaging in your checked bag, within the weight limit. Declare them at check-in.
