Firearms - There are specific regulatory requirements to transport a firearm:

* The firearm must be checked with the air carrier as luggage. Firearms are prohibited from carry-on baggage.
* The firearm must be declared orally or in writing in accordance with the air carriers procedures (contact your air carrier for their specific procedures).
* The firearm must be unloaded.
* The firearm must be carried in a hard-sided container.
* The container must be locked and only the passenger may retain the key or combination.

All checked baggage is subject to inspection. If during the inspection process it is necessary to open the container, air carriers are required to locate the passenger and the passenger must unlock the container for further inspection. The firearm may not be transported if the passenger can not be located to unlock the container. If you are traveling with a firearm, pay close attention to airport pages and announcements. If requested, provide the cooperation necessary to inspect your firearm.

Ammunition - Ammunition is likewise prohibited from carry-on luggage. Ammunition may not be carried loose. It must travel in the manufacturer's packaging or other packaging suitable for transport. Consult your air carrier to determine quantity limitations or whether the ammunition must be packed separately from the firearm.


I've read horror stories of encounters with airline and security personnel not aquainted with the rules. The (good) suggestion is to go to the TSA website and pring this info. Then go to the airline's website and do likewise. Then have that with you at the airport so you are able to educate the uninformed, should the situation arise.
