The number of guns found in carry-on bags at Chicago's Midway International Airport rose last year.
The Transportation Security Administration released figures Thursday showing the number at Midway went from six in 2014 to 16 last year.
Nationwide, firearm discoveries at airport security checkpoints rose nearly 20 percent in 2015 to hit a record 2,653. Nearly 83 percent of them were loaded.
While the number went up at Midway, it declined at O'Hare International Airport, falling from 20 in 2014 to 16 last year.
Dallas/Fort Worth International Airport saw the biggest number. Screeners there intercepted 153 guns last year.
Firearms and ammunition are prohibited in carry-ons. They can be transported in checked baggage if they are unloaded, properly packed and declared to the airline.
