The Transportation Security Administration intercepted a record number of firearms at the nation’s airports in 2015, a 20 percent increase over the high set the previous year, the agency said. Most of the firearms were loaded.

TSA scanners and personnel found 2,653 firearms in carry-on bags, up from 2,212 in 2014, the agency said Thursday. Of the guns seized in 2015, the agency said 2,198, or nearly 83 percent, were loaded.

One passenger at the Orlando International Airport “concealed two handguns, one unassembled rifle, and an unidentified amount of ammunition inside three amplifiers in a checked bag,” TSA said.

The airports with the most firearm interceptions were Dallas/Fort Worth International Airport (153); Hartsfield-Jackson Atlanta International Airport (144); Houston George Bush Intercontinental Airport (100); Denver International Airport (90); and Phoenix Sky Harbor International Airport (73).

In the Washington, D.C. area, the TSA intercepted 14 at Ronald Reagan Washington National Airport, the same as in 2014, and 20 at Washington Dulles International Airport, up from nine in 2014.

Those who bring firearms to the security checkpoints or fail to declare them in checked luggage can run afoul of criminal and civil charges.

In addition, the TSA on Thursday also offered a rundown on the scope of its monitoring, saying that more than 708 million passengers underwent screening in 2015. That was up 40.7 million, or nearly 6 percent from the previous year.

And you may think you wait a long time for airport screenings, but the TSA said that nationwide, less than 2 percent of passengers waited in line longer than 20 minutes.
