Travelers may only transport UNLOADED firearms in a locked, hard-sided container as checked baggage. All firearms, ammunition and firearm parts, including firearm frames, receivers, clips and magazines are prohibited in carry-on baggage.
Realistic replicas of firearms are also prohibited in carry-on bags and must be packed in checked baggage. Rifle scopes are permitted in carry-on and checked bags.
In addition to TSA security rules on transporting firearms, airlines, as well as state, local and international governments have additional rules that may vary by location. Please check with your airline and with states and cities you will be traveling into and out of to become familiar with their requirements and ensure you are compliant with their laws. Before traveling outside of the United States with firearms and/or ammunition, you should also read U.S. Immigration and Customs Enforcement’s guidance.

Many U.S. households have guns, but they can cause harm if not handled properly. Here are some things you can do to keep yourself and your family safe:
•Teach children that they shouldn't touch guns and that if they see a gun, to leave it alone and tell an adult.
•If your children play at another home, talk to the parents about gun safety.
•Treat every gun as if it were loaded.
•Always store guns unloaded.
•Lock guns in a rack or safe, and hide the keys or combination.
•Store ammunition away from guns and keep it locked.
•Don't keep guns in your home if someone in your family has a mental illness, severe depression, or potential for violence.
