A TSA spokesperson says agents found two loaded firearms in carry-on luggage in North Dakota in the past week.
An agent at the Minot International Airport found a 9 MM Ruger loaded with six rounds on Friday.
Wednesday, the TSA found a Smith & Wesson M+P Gody Guard loaded with five rounds plus another in the chamber at the Bismarck Airport.
Agents confiscated the weapons and the passengers face more than $10,000 fines.
Travelers must always check firearms and look-alikes and declare them at the airport before flying.
