Can you bring a firearm on a plane?

Yes — in checked baggage only, on every US airline. The firearm must be unloaded, packed in a locked hard-sided container that only you can open, and declared at the ticket counter, where you'll sign a declaration card that travels with the case. A firearm in a carry-on, even forgotten, is a federal civil penalty and usually a missed flight. Curbside and kiosk check-in don't work for firearms, so go to the counter and build in extra time.

How much ammunition can you fly with?

TSA itself sets no weight limit — the limit is airline policy. Most carriers, including United, WestJet, and Air Canada, cap small-arms ammunition at 11 lb (5 kg) per passenger. Alaska Airlines is the outlier at 50 lb per passenger on domestic mainline flights, though certain regional and international routes drop back to 11 lb. If your itinerary mixes carriers, the strictest airline on the ticket effectively wins.

How does ammunition have to be packed for a flight?

In checked baggage only, in boxes designed for ammunition — the original manufacturer box or fiber, wood, plastic, or metal ammo boxes. Loose rounds in a duffel get refused at the counter, and loaded magazines must be boxed or enclosed too. TSA allows ammo inside the same locked hard case as the rifle, but individual airlines can be stricter: Air Canada requires ammunition in a separate container from the firearm.

Can you use TSA-approved locks on a gun case?

Not as the only locks. TSA-approved locks are designed so screeners can open them with a master key, and a firearm container is required to be one that only you can open — if TSA needs it inspected, they summon you rather than opening it themselves. On a plain reading, a gun case secured only by TSA-accessible locks fails that requirement. Use real locks on the firearm case, and use every lock hole the case has.

Can you fly with bear spray?

Effectively no. The FAA treats aerosol animal repellent as a hazardous material and caps it at 4 fl oz in carry-on or checked baggage, and most bear sprays exceed that size. Some carriers, Alaska Airlines among them, prohibit bear spray entirely regardless of size, and international rules are stricter still. Plan on buying a can at your destination and giving it away before you fly home.

What do you need to bring a hunting rifle into Canada?

The airline's rules get you to the airport; the border has its own. Non-residents flying into Canada with a hunting rifle use the RCMP Non-Resident Firearm Declaration, presented at customs — and the single most important instruction is to sign it in front of the border officer, not before. Air Canada specifically also charges a CA/US$50–60 firearm handling fee each way, limits passengers to three firearms, and requires ammunition packed separately from the gun.

Flying With Firearms & Ammo: Airline Rules for Hunters

Every fall, hunters miss flights, lose hunting days, or pick up federal penalties over a process that — done right — takes ten extra minutes at the ticket counter. Flying with a rifle is routine: airlines carry thousands of firearms a day. The hunters who have problems are almost always tripped by one of a half-dozen known failure modes, and every one of them is preventable.

Here's the process, the rules that are actually federal versus airline policy, and the mistakes to warn every traveling hunter about. Rules verified against TSA and airline pages as of this writing — policies change, so confirm with your specific airline before every trip.

The federal baseline (TSA)

These rules apply on every US airline, every flight:

Checked baggage only. No firearm, ever, in a carry-on — including “I forgot it was in there” (that one's a federal civil penalty and often a missed flight).
Unloaded, in a locked, hard-sided container, and only you hold the key or combination. If a TSA officer needs it opened, they'll summon you — a case a stranger can open is not “locked” for this purpose.
Declare it at the ticket counter, every time. You'll sign a declaration card that goes with the case. Curbside and kiosk check-in don't work for firearms — go to the counter, and build in extra time.
Ammunition never flies in a carry-on. In checked bags, small-arms ammo must be in boxes designed for ammunition — the original manufacturer box or fiber, wood, plastic, or metal ammo boxes. Loose rounds rattling in a duffel get refused. Magazines must be boxed or enclosed too.
Ammo may ride inside the same locked hard case as the rifle — convenient and TSA-legal, but airlines can be stricter, and some are: Air Canada requires ammunition in a separate container from the firearm.
One rule most hunters get backwards: TSA sets no ammo weight limit. The famous “11 pounds” is airline policy (derived from hazmat carriage rules), not TSA's — which is why the limit varies by carrier.

Airline limits worth knowing (verified July–August 2026)

Airline	Ammo limit	Notable firearm rules
Alaska	50 lb per passenger on domestic mainline flights (11 lb on certain regional and international routes)	No limit on firearms per case; crush-proof ammo packaging; bear spray prohibited entirely
United	11 lb (5 kg)	Up to 5 firearms in one case; counter check-in plus signed declaration; 18+
WestJet	11 lb (5 kg) gross	Locked hard case; non-restricted rifles need no extra internal lock; 72-hour advance contact when partner airlines fly international segments
Air Canada	11 lb (5 kg) per passenger — allowances can't be combined between passengers	Ammo must not share the firearm's container; max 3 firearms per person; one signed declaration per container; CA/US$50–60 handling fee each way; arrive 30 minutes earlier than normal

Two takeaways: Alaska Airlines is by far the most generous carrier for hunters hauling ammo north — nearly five times the standard limit — and if your itinerary mixes carriers, the strictest airline on the ticket wins. Book accordingly.

The six failure modes

The TSA-lock mistake. TSA-approved locks (the ones screeners can open with a master key) are for regular luggage. A firearm case secured only by TSA-accessible locks fails the “only you have the key” requirement on a plain reading — use real locks on the gun case, and use every lock hole the case has.
A soft case inside a hard story. “Hard-sided” means the case itself: a soft rifle sleeve inside a plastic tote doesn't qualify. Buy a real flight case with a full-perimeter seal; your scope's zero is riding on it too.
Loose or wrong-boxed ammo. Original boxes or purpose-made ammo boxes. Not a ziplock, not a sock. If the airline refuses the ammo, you're unpacking your duffel at the counter with a line behind you.
Tight connections. A declared firearm adds handling steps at both ends. Give yourself a longer connection than you think you need — and remember weather-delay math gets worse when a gun case has to make the transfer with you.
Forgetting the destination's rules. The airline gets you there; it doesn't make you legal on arrival. Flying into Canada for a hunt means the RCMP Non-Resident Firearm Declaration at customs — we wrote the complete guide to that process, including the one instruction that matters most (don't sign the form before the border). Driving or connecting through other countries adds their rules on top.
Bear spray in the duffel. The FAA treats aerosol animal repellent as hazardous material and caps it at 4 fl oz in either bag — and most bear sprays are bigger than that, so effectively it doesn't fly. Some carriers (Alaska among them) prohibit it outright regardless of size. Buy it at your destination, give it away when you leave.

Arrival-day advice for your clients (the outfitter section)

If you outfit for fly-in clients, the rifle is the single most common travel failure point — and it's your opening morning that gets burned. Three things professional operations do:

Send this checklist at booking. A one-page “how to fly with your rifle” email prevents most of the above. (Share this post — that's what it's for. It pairs with the guided hunt packing list.)
Know what's coming. Hunt Outfitter captures each client's firearms details on their profile — type, make, model, caliber, bullet weight — on every plan, so you know before camp who's bringing what and can flag problems (the 6.5-for-moose conversation) while there's still time to fix them.
Have a loaner-rifle answer. Delayed gun cases happen even when everyone does everything right. Clients who know your policy in advance panic less at the baggage office.
