(CNN)When packing your carry-on luggage, don’t forget to remove your gun.

Unless you’ve got permission, not remembering could get you in trouble.

The U.S. Transportation Security Administration seized a record 2,212 firearms from carry-on luggage in 2014, the U.S. Department of Homeland Security reported Friday.

That’s more than the TSA has seized in any other year of its existence, and it’s a 22% increase from the 1,813 guns seized in 2013. (The agency actually hit a record 2,000 seizures on December 1, before the year was over.)

That’s an average of six guns per day.

Of those discovered, 83% were loaded.

The department’s employees “stand on the front lines protecting our nation from dangerous contraband and people, while ensuring the free flow of lawful trade and commerce — just two aspects of our mission,” Homeland Security Secretary Jeh Johnson said in a news release.

“This is critically important work, and our employees’ achievements are self-evident: in 2014, the TSA screened more than 650 million passengers, nearly 1.8 million each and every day,” Johnson said.

Dallas/Fort Worth International Airport security seized the most guns last year, with 120. Hartsfield-Jackson Atlanta International Airport came in second place with 109 gun seizures, and Phoenix Sky Harbor International Airport came in third place with 78 gun seizures.

Houston George Bush Intercontinental Airport had 77 gun seizures, while Denver International Airport had 70.

Forgetting can be expensive and even criminal.

Passengers whose guns are spotted by TSA security during the screening process can be arrested by airport or local police and face criminal charges, and the TSA can impose civil penalties. Members of TSA Pre-check can be temporarily or permanently banned from the expedited screening program.
