How to Fly With Firearms: TSA Rules and Case Requirements

TSA Rules for Flying With Firearms

Traveling with firearms by air is legal in the United States, but there are strict rules. Understanding them before you get to the airport saves time and prevents confiscation.

The Basic Requirements

Firearms Must Be Checked — Never Carry-On

All firearms must be transported in checked luggage. No exceptions. This includes handguns, rifles, shotguns, and firearm frames or receivers.

Hard-Sided, Locked Case

The case must be hard-sided and locked with a non-TSA lock. This is important — unlike regular luggage, firearm cases should use locks that only you can open. TSA uses their master keys on regular luggage, but firearm cases are opened in your presence during inspection.

Unloaded

The firearm must be completely unloaded. No round in the chamber, no loaded magazines inserted. TSA agents will verify this during inspection.

Ammunition Rules

Ammunition may be transported in checked luggage. It must be in the original packaging or a container designed for ammunition (not loose in the case). Small arms ammunition (up to .75 caliber) is permitted.

Loaded magazines are technically allowed by TSA if they're securely boxed, but many airlines prohibit them. Check your specific airline's policy.

Declaration

You must declare the firearm at the airline check-in counter. They'll provide a declaration card that goes inside the case. You'll typically be escorted to a TSA inspection area where the case is opened, inspected, and cleared.

Case Requirements in Detail

Hard-Sided

Soft cases, range bags, and fabric cases are not permitted. The case must be rigid enough that it cannot be easily pried open. Pelican, Nanuk, and SKB cases all meet this requirement.

Completely Securable

The case must be lockable and must completely prevent access when locked. All latches must close fully, and there should be no gaps where fingers could access the interior.

Locks

Use non-TSA padlocks. Abloy, Abus, and Master Lock No. 3 are popular choices. Many travelers use two locks — one on each lock point. Combination or keyed locks both work, but keyed locks are faster during inspection.

Step-by-Step Airport Process

1. Pack at Home

Unload the firearm completely. Place it in the hard case with custom foam. Pack ammunition in a separate container within the same case or in a separate checked bag. Include a small lock for the ammunition container if your airline requires it.

2. Check-In Counter

Declare the firearm to the agent. They'll give you a declaration tag to fill out and place inside the case. Some airlines handle this at the regular counter; others direct you to a special counter.

3. TSA Inspection

You'll be directed to a TSA screening area. Open the case for the agent to verify the firearm is unloaded. The agent will inspect the case, lock it in your presence (you keep the keys), and clear it for checked baggage.

4. Retrieval

At your destination, retrieve the case from the oversized baggage area or regular carousel depending on the airport.

Airline-Specific Notes

Each airline has additional policies on top of TSA requirements:

• Ammunition limits — some airlines cap the amount (typically 11 lbs)
• Fees — most airlines charge standard checked bag fees; some add a firearms surcharge
• Number of firearms — multiple firearms in one case is usually fine if the case meets requirements
• Ammunition in magazines — varies by airline. Check before you fly

Tips for a Smooth Experience

• Arrive early — the inspection process adds 15-30 minutes
• Print TSA and airline rules — having documentation ready helps resolve disputes with agents who may not know the rules
• Use a quality hard case — flimsy cases can be rejected
• Custom foam prevents issues — a well-organized case with visible contents speeds up inspection
• Know state and local laws — your destination may have laws about specific firearms or magazine capacities

The Right Case Setup

A hard case with custom CNC-cut foam makes the TSA process smoother. When agents can see exactly what's in the case — each item in its own clearly defined cavity — inspections go faster. Foam with finger pulls lets agents lift items for inspection without handling the firearm extensively.
