✈ Traveling With a Firearm: Air, Land & Sea
The single biggest mistake travelers make is assuming their permit — or even federal "safe passage" protection — covers every leg of the trip. It does not. Each mode of travel has its own federal rules layered on top of state law. Read all three before you leave.
By Air
✈ Flying (TSA / FAA)
- Never in carry-on. Firearms are forbidden at the checkpoint and in the cabin — no exceptions, even with a CCW.
- Firearm must be unloaded and in a locked, hard-sided case only you can open. Do not use TSA-master-key locks.
- Declare it at the airline ticket counter; a "firearm unloaded" tag goes inside the case.
- Ammunition rides in checked baggage only, in an ammo box. Many airlines cap it near 11 lbs.
- You must legally possess it at both airports. Landing in NY, NJ, MD, or HI with a standard mag or no local permit can mean arrest.
By Land
🚗 Driving (FOPA §926A)
- Safe Passage (18 U.S.C. §926A) lets you transport a firearm between two places you may legally possess it, even through a restrictive state — if you keep moving.
- Firearm must be unloaded and not readily accessible from the passenger compartment — trunk, or a locked container if no separate trunk.
- Ammunition separate is best practice and required in some states (e.g. NJ/PA/DE).
- Protection is lost if you stop, detour, or stay — overnight stops have led to arrests in NY/NJ.
- Carrying loaded/accessible requires a permit the state actually honors — that's what the map is for.
By Sea
⚓ Boat / Ferry / Cruise
- On your own vessel, the law of the state whose waters you're in applies — reciprocity works like driving.
- Cruise lines almost universally ban firearms, even checked. They will confiscate and may deny boarding.
- Foreign ports (Bahamas, Mexico, Canada) have severe penalties — a single round can mean prison.
- Entering another state's waters or a federal facility/port can trigger federal rules. Store unloaded and locked.
- Amtrak allows declared, checked firearms (24 hr notice) on most routes — never on your person.
🇨🇦 Crossing Into Canada (and Mexico): Don't.
For most Americans the honest answer at the northern border is "leave it home." Your U.S. permit means nothing in Canada, and Canada classifies firearms far more strictly than any U.S. state.
- Handguns are effectively barred. Since Canada's 2022 freeze, you generally cannot bring a handgun across the border for protection or transport. "Self-defense" is not a valid reason to import any firearm.
- AR-pattern & many semi-autos are "prohibited" and cannot enter under any circumstance.
- Only non-restricted long guns (most ordinary hunting rifles/shotguns) may enter — and only with a written Non-Resident Firearm Declaration and a $25 fee, transported unloaded and locked out of sight.
- You must declare every firearm. Failing to declare = seizure, fines, and criminal charges, and you'll be turned around.
- Mexico is stricter still — even one round of ammunition can mean serious prison time. Do not cross armed.
Verify current rules with the Canada Border Services Agency (CBSA) before any trip — these laws change and are strictly enforced.
🚫 Do-Not-Cross Lines: Quick Warnings
- Do NOT drive into a restrictive (red) state with a loaded firearm or one accessible from the cabin.
- Do NOT bring a magazine over the state limit (often 10 rounds — CA, CT, MD, MA, NJ, NY, WA, HI, RI, DC; 15 in CO & VA). A 17-round mag is a felony in several states regardless of your permit.
- Do NOT assume a permit covers "assault weapon" / AR-pattern firearms — banned states (CA, NJ, NY, CT, MA, MD, IL, HI, WA, DE, RI, DC) restrict the firearm itself.
- Do NOT carry into federal buildings, schools, courthouses, military bases, post offices, or secured airport areas.
- Do NOT rely on permitless carry without confirming the minimum age (usually 21) and that you are not a prohibited person.
- Do NOT cross into Canada or Mexico with a handgun or undeclared firearm — see the border box above.
