TSA screeners found a record number of firearms in airline passenger carry-on bags last year, according to data released Thursday by the agency.
An average of nearly 12 weapons were found every day, for a total of 4,239 during all of 2018.
The discoveries came during a year that saw airline travel up by 5.5 percent over 2017. TSA said "significant security enhancements" also contributed to the record number of guns found.

Nearly nine out of every 10 of the weapons found were loaded, the TSA said, and of those a third had a round chambered. The guns were found at 249 of the nation's 440 airports where TSA conducts the screening.
The airports with the largest number of firearms seizures were in the South and the West. Atlanta's Hartsfield-Jackson led the list, followed by Dallas/Fort Worth, Phoenix, Denver, and Orlando, Florida. Four of the top 10 were in Texas: George W. Bush Intercontinental in Houston, Austin-Bergstrom, Dallas/Fort Worth and Dallas Love Field.
