The rate was double that in 2019, when screeners found 5 guns for every million passengers. Screeners found 220 guns at Hartsfield-Jackson Atlanta International Airport, followed by 176 at Dallas/Fort Worth International Airport, 126 at George Bush Intercontinental Airport in Houston, 126 at Phoenix's Sky Harbor International Airport, and 104 at Denver International Airport. Federal law prohibits passengers other than certain law enforcement officers from bringing guns or ammunition into the cabin. Federal law allows passengers to put guns in checked bags that go into the cargo hold if they are unloaded and in a locked case. Airlines don't have to permit guns even in checked bags.
