Traveling With a Firearm (2026): TSA, Airline & Interstate Rules
Quick answer: To fly with a gun in the U.S., the firearm must be unloaded, locked in a hard-sided container and placed in checked baggage, and you must declare it at the airline counter. Guns are never allowed in carry-on bags. To drive across state lines, confirm your permit is recognized in every state on your route; if it is not, federal law (18 U.S.C. § 926A) protects transport only when the gun is unloaded and locked away out of reach, and only if you can legally possess it at both ends of the trip.

Travel Rules at a Glance
| Situation | What you need to know |
|---|---|
| Flying (TSA) | Unloaded firearm, locked hard-sided case, checked bag only, declared at check-in. You keep the key or combination. |
| Ammunition when flying | Checked bags only, securely packaged. Airlines often limit quantity (commonly 11 lb / 5 kg) — check your carrier. |
| Magazines | Loaded or empty, they must be securely boxed or packed in the hard case with the unloaded firearm. |
| Driving with a recognized permit | Carry under that state’s rules, including prohibited places, magazine limits and duty to inform. |
| Driving through a state that does not recognize your permit | Rely on 18 U.S.C. § 926A: unloaded, not readily accessible from the passenger compartment (locked container, not the glove box or console, if there is no trunk). |
| Hotels and rentals | Policies vary by property. Use a lockbox and never leave a firearm unsecured in a room or car. |
Flying With a Firearm
TSA requirements
- Firearms and firearm parts must be unloaded and locked in a hard-sided container and travel only in checked baggage.
- Declare the firearm to the airline at the ticket counter during check-in.
- TSA treats a firearm as “loaded” when the gun and its ammunition are both accessible to you — so never pack a gun in a carry-on, even unloaded.
- Bringing a firearm to a checkpoint can lead to arrest and federal civil penalties. Check every bag before you leave home.

Airline rules
Airlines can add their own limits on ammunition weight, case requirements, fees and international travel. Read your carrier’s policy before booking:
- American Airlines firearms policy
- Delta firearms policy
- United firearms policy
- Southwest firearms policy
Also check the destination state’s possession laws before you fly. Federal checked-bag rules do not make it legal to possess a handgun in a place where state or local law prohibits it.
Driving Across State Lines
- Check recognition on your whole route. A permit valid at home may not be valid in the next state. See our concealed carry reciprocity breakdown and what constitutional carry means.
- Know each state’s rules: prohibited places, magazine limits, ammunition restrictions and whether you must inform an officer during a stop (see our traffic stop guide).
- Where you cannot legally carry, switch to federal safe-passage transport: unloaded, locked away and not readily accessible. Stops along the way can complicate that protection, so keep them brief.
- Secure the gun whenever you leave the car. Vehicle thefts are a common source of stolen firearms. See our vehicle firearm storage and transport guide.
Pre-Trip Checklist
- Confirm permit recognition or permitless-carry eligibility in every state on the route.
- Read the destination’s possession, transport and magazine rules.
- If flying: hard case, your own locks, unloaded firearm, boxed magazines and ammunition, and your airline’s policy printed or saved.
- Check hotel or rental firearm policies.
- Pack your ID, permit and proof of ownership if a state requires it.
- Save the number for your carry-insurance or legal-defense hotline.
Legal Protection While Traveling
Out-of-state incidents can be harder to manage than ones at home. Many carry-insurance and legal-defense plans include a 24/7 hotline and attorney network. Compare options in Best Concealed Carry Insurance Compared.
Traveling With a Firearm FAQ
Can I fly with a gun?
Yes, within the U.S. the gun must be unloaded, locked in a hard-sided container, packed in checked baggage and declared to the airline at check-in. It is never allowed in a carry-on bag.
Can I bring ammunition on a plane?
Only in checked baggage, securely packaged. Many airlines cap ammunition at 11 pounds (5 kg) per passenger; check your airline’s policy.
Can I drive through a state that does not honor my permit?
Federal law (18 U.S.C. § 926A) protects transport through a state if you may legally possess the firearm at your origin and destination, and the gun is unloaded and not readily accessible from the passenger compartment. It does not authorize carrying the gun loaded on your person.
Do I have to tell police I have a gun if I am pulled over in another state?
It depends on that state’s duty-to-inform law, not your home state’s. See our traffic stop guide for the current list.
Can I keep a gun in a hotel room?
It depends on the hotel’s policy and local law. If permitted, keep it in a locked container and never leave it unsecured while you are out.
