Travelers may only transport UNLOADED firearms in a locked, hard-sided container in or as checked baggage. All firearms, ammunition and firearm parts, including firearm frames and receivers, are prohibited in carry-on baggage.
Firearm possession laws vary by state and locality. Travelers should familiarize themselves with state and local firearm laws for each point of travel prior to departure.
Airlines may have additional requirements for traveling with firearms and ammunition. Travelers should also contact the airline regarding firearm and ammunition carriage policies.
Also, please note that other countries have different laws that address transportation and possession of firearms. If international travel is planned, check the regulations of the destination country to ensure compliance with their requirements.
Do not exceed airline weight allowance of 11 pounds gross weight (five Kgs.) for both ammunition and packaging.
