Passengers who travel with firearms should understand Frontier Firearm Policy Items before packing. Firearms must be unloaded, declared at check-in, and secured in a locked, hard-sided case. They are accepted as checked baggage only, and ammunition must be properly packaged. Cabin carriage is not allowed under any circumstances. Laws at your destination may be stricter than expected, so review them early. Visit the official Frontier Airlines website for current guidance, and give yourself extra time at the counter for a worry-free start to your trip.
