Which airports caught the most firearms?

The number of guns found in security checkpoints varies by state and airport. The Hartsfield-Jackson Atlanta International Airport (ATL) had the largest number of guns caught in 2021 at 507. In 2020, ATL also ranked the highest in guns caught by TSA at 220, less than half the amount than the following year.

The top four airports with the highest number of guns caught by TSA did not change from 2020. In 2021, the Louis Armstrong New Orleans International Airport entered the top 10, knocking Las Vegas McCarren International Airport out of the list.

People may not travel with firearms in the passenger cabin, even if they have a concealed weapon permit.[1] Travelers are not allowed access to firearms during a flight and must store their unloaded firearms in checked baggage following TSA guidelines.
