Flying With a Gun: TSA Rules and Atlanta Airport Tips

You can fly with a gun, but only in checked baggage. It must be unloaded, packed in a locked, hard-sided case, and declared to the airline at the ticket counter. It cannot go in your carry-on, ever. That is the rule from TSA, the federal agency that screens airline passengers, and it is the same at Atlanta’s Hartsfield-Jackson airport as anywhere else.

This guide walks through what TSA says, how to pack, and what to know if you are flying out of Atlanta. It covers the airline travel rules only. It does not cover the gun laws of the place you are flying to. This is general information, not legal advice, and it is current as of November 2026.

The rules in one list

These come straight from TSA’s page on transporting firearms and ammunition.

• Checked bag only. You may transport unloaded firearms in a locked, hard-sided container as checked baggage only.
• Unloaded. TSA also treats a firearm as loaded if the firearm and ammunition are both accessible to you at the same time.
• Declare it. Tell the airline about the firearm and any ammunition when you check your bag at the ticket counter.
• Use a case that truly locks. The container must completely secure the firearm from being accessed. Locked cases that can easily be opened are not permitted.
• Keep the key. Only you should keep the key or combination, unless TSA staff ask for it.
• Ask your airline. TSA says to ask the airline about any limits or fees.

Each of these has a reason, and the sections below cover them in order.

Why the carry-on rule has no exceptions

TSA says firearms are not allowed in carry-on baggage. The same goes for firearm parts, including magazines, clips, bolts and firing pins, which are prohibited in carry-on bags. Replicas, including toy replicas, must go in checked baggage as well.

One item you can carry on is a rifle scope. TSA says scopes are permitted in both carry-on and checked baggage.

The penalty for getting this wrong is real. TSA says bringing an unloaded firearm with accessible ammunition to the checkpoint carries the same civil penalty as bringing a loaded one. TSA’s 2025 report on Georgia says civil penalties can reach $14,950 per violation, and PreCheck eligibility can be revoked for up to five years. Local airport law enforcement decides whether to issue a criminal citation or make an arrest.

How to pack a gun for a flight

Start with the gun itself, then the case, then the ammunition.

Unload it and check it twice. The gun must be unloaded before it goes in the case. Check the chamber and the magazine.

Use a hard-sided case with real locks. TSA says the case a firearm came in at purchase may not be secure enough for checked baggage. A case that can be easily opened does not qualify. TSA says you may use any brand or type of lock, including TSA-recognized locks, and that only you should keep the key.

Pack ammunition the right way. TSA says small arms ammunition, up to .75 caliber and shotgun shells of any gauge, must be packed in a fiber, wood, plastic or metal box made for ammunition. It is prohibited in carry-on bags but may go in checked baggage, and TSA says it may share the locked, hard-sided case with the firearm if packed this way. Many airlines cap the amount you can bring, so check yours.

Box the magazines. TSA says firearm magazines and ammunition clips, loaded or empty, must be securely boxed, or placed in the hard-sided case with an unloaded firearm.

Keep the key on you. Do not put the key or combination in the checked bag.

At the airline counter

You declare the gun at the airline’s ticket counter, not at the TSA checkpoint. TSA says to declare the firearm and any ammunition when you check your bag, and to declare each firearm each time you check it.

Plan for extra time. The airport says to arrive at least two hours before a domestic flight and three hours before an international one (Hartsfield-Jackson, passenger security). If you are checking a firearm, build in more on top of that so the declaration is not rushed.

What to know at Atlanta’s airport

Atlanta’s airport leads the country in guns found at the security checkpoint. TSA reported that its officers found 440 firearms in carry-on bags at Hartsfield-Jackson in 2024, the most of any U.S. airport. That is down slightly from 451 in 2023.

What that means for you is simple. A gun left in a carry-on is the mistake TSA finds at the checkpoint. Before you leave the house, empty every bag you plan to carry on. A coat pocket or a bag you used on the range last week can still hold a gun or ammunition.

The airport’s own advice points the same way. In a press release, Hartsfield-Jackson told travelers that firearms and ammunition must be packed properly and placed in checked bags only, and sent them to TSA for details (Hartsfield-Jackson press release).

Gear and accessories: what goes where

Not everything in a gun bag follows the same rule. Here is how TSA sorts the common items, all from the same TSA page.

• The gun: checked bag only, unloaded, in a locked hard-sided case.
• Ammunition: checked bag only, in a box made for it.
• Magazines and clips: checked bag only, boxed or in the case with the unloaded firearm. TSA says this holds loaded or empty.
• Bolts, firing pins and other parts: not allowed in carry-on.
• Rifle scopes: allowed in carry-on and in checked baggage.
• Replicas and toy guns: checked baggage only.

If an item is not on this list and you are not sure, TSA says to contact AskTSA or the TSA Contact Center to ask what you can pack. That is better than guessing at the checkpoint.

Airlines have their own rules

TSA sets the floor. Airlines can add to it, for example by limiting how much ammunition you can bring or charging a fee. TSA says to ask your airline about limitations or fees. Do it before you pack, not at the counter.

The place you are flying to has its own laws

This guide stops at the airport. TSA tells travelers to comply with the laws on possessing firearms as they vary by local, state and international governments. If you are flying to another state, check the laws there before you go. For a trip out of the country, TSA points to U.S. Customs and Border Protection. We do not give advice on gun laws elsewhere.

If you are buying a gun for the trip

Some people buy a gun right before a trip. Buying from a licensed dealer means you will fill out ATF Form 4473 and show ID, and the dealer records the firearm and its serial number (27 CFR 478.124). If you bought a gun online and it is shipping to a shop for you, the transfer has to be finished at the shop first. Give yourself time for that before your flight.

At Lakeside Munitions in Cumming, an FFL transfer is $40 flat per firearm, and we log each one in the day it arrives, any day we are open. Our FFL transfers page has the full steps and what to bring.

A short checklist before you leave for the airport

1. The gun is unloaded.
2. It is in a hard-sided case that locks and cannot be easily opened.
3. The key or combination is with you, not in the bag.
4. Ammunition is in a proper box, and you know your airline’s limit.
5. Magazines are boxed or in the case.
6. Every carry-on bag is empty of firearms, parts and ammunition.
7. You have asked your airline about its rules and fees.
8. You know the gun laws where you land.
