The number of firearms seized from travelers at the Washington region’s airports rose 34 percent last year compared to the previous year, the Transportation Security Administration said Thursday.

A total of 67 firearms showed up in carry-on bags brought to Baltimore Washington International Thurgood Marshall, Dulles International, and Ronald Reagan National airports in 2016, compared with 50 in 2015, a TSA spokeswoman said.

Dulles and BWI were tied, with 24 seizures apiece, compared with 20 at Dulles and 16 at BWI in 2015. TSA agents seized 19 firearms at National Airport last year, compared with 14 the year before.

Nationwide, 3,391 firearms were detected in carry-on bags at TSA checkpoints, or about nine per day. That represents an increase of about 28 percent from 2,653 in 2015. The agency also said 83 percent of the firearms seized last year were loaded.

The latest increase comes after a record number of firearms were detected at the nation’s airports last year.

It is legal to transport firearms in checked baggage if they are stowed unloaded in a hard-sided, locked case separate from ammunition, and their presence is declared to airline representatives at check-in. Travelers who try to bring firearms through TSA checkpoints can face criminal charges and civil penalties, including the confiscation of the firearm.
