The TSA urged passengers travelling with guns to pack their weapons in approved, locking hard-case containers. "Please don't pack your firearm in your carry-on bag and please check your bags before heading to the airport."
The maximum fines for carrying a weapon in an airport is US$13,333 ($20,000) per incident, and possible jail sentences.
Of the most unusual contraband items reported by the TSA were two missile launchers confiscated at Washington International Airport, in two separate incidents.
On July 29 a security contractor returning from Kuwait arrived at the airport with a rocket launcher in his checked luggage. The following week a US Air Force sergeant was found transporting another rocket launcher tube.
While neither launcher contained explosives and were souvenirs of training exercises, military issue arms are not allowed to be transported through US Airports.
