The TSA said its officers caught more firearms at checkpoints nationwide in 2019 than ever before in the agency’s 18-year history.

In total, 4,432 firearms were discovered in carry-on bags or on passengers at checkpoints across the country last year, averaging about 12.1 firearms per day, approximately a 5% increase nationally in firearm discoveries from the total of 4,239 detected in 2018. Eighty-seven percent of firearms detected at checkpoints last year were loaded.

“The continued increase in the number of firearms that travelers bring to airport checkpoints is deeply troubling,” said TSA Administrator David Pekoske. “There is a proper way to travel safely with a firearm. First and foremost, it should be unloaded. Then it should be packed in a hard-sided locked case, taken to the airline check-in counter to be declared, and checked.”

TSA said that firearms were caught at 278 airport checkpoints nationwide.
