A "firearm" is any weapon that will, is designed to, or may readily be converted to expel a projectile by the action of an explosive; or the frame or receiver of any such weapon. See firearms list.
Firearms checklist
You may transport firearms as checked baggage only.
You must be 18 years of age or over to transport a firearm.
Firearms must be unloaded and carried in a locked, hard-sided container.
Container must be completely secure so that it does not allow for accidental or unauthorized access.
Multiple locks may be required on some cases to ensure the case cannot be opened.
Only the passenger shall have the key or combination to the lock.
Passenger may need to supply the key or combination upon request from the TSA when the case is screened.
Container must not hold dangerous goods or prohibited items, such as, but not limited to, loose ammunition, flammable liquids, black powder, primers, or bear spray. You are responsible for knowing and complying with all relevant laws that concern possession of firearms. Those laws vary by local, state, and international governments.
If you plan to travel internationally with a firearm in checked baggage, please read the requirements on the U.S. Customs and Border Protection website before you travel.
Ammunition checklist
Ammunition is prohibited in carry-on baggage.
You can transport it in checked baggage if it's within weight allotments.
Customers checking in or connecting to Alaska Airlines flights 3300-3499 are limited to 11 lbs. of ammunition.
Ammunition must be securely packed in the original manufacturer packaging or in a container designed for ammunition.
The packaging shall be of sufficient strength to protect the ammunition from accidental crushing or discharge (e.g. wood, fiber, plastic, or metal).
We will not accept loose ammunition in a box, bucket or manufacturer packaging.
The projectile must be no larger than 11/16" in diameter—the size of a dime.
You may check ammunition with or separately from the firearm.
