This note is actually pretty useful and reminds locals: "TSA says there are legal ways to travel with your gun. But if you forget, you're facing a fine of up to $13,000 and a possible arrest."
In 2019, 67 guns were seized at security checkpoints at Kansas City International Airport. That is just one shy of the record set in 2017. But seven years ago that number was just 14. Last year, according to the federal Transportation Security Adminsitration, 48 firearms were discovered by screeners.
