Some travelers continue to ignore warnings about bringing firearms in their carry-on baggage.

Transportation Safety Administration officers seized two loaded guns at the security checkpoint at the Boise Airport Sunday morning.

The first handgun was found at around 7 a.m. It was a Smith & Wesson M&P Shield 9 mm semiautomatic found in the in the carry-on bag of a male passenger headed to Portland. The gun was loaded with eight rounds of ammunition.

The second firearm - also a Smith & Wesson M&P Shield 9 mm semiautomatic handgun- was detected at around 11 a.m. in the carry-on of a male passenger bound for Salt Lake City. It was loaded with seven rounds of ammunition.

“There is a definite trend and it is not a good one. Too many people are bringing loaded firearms into airports and showing up at TSA checkpoints nationwide,” said Andy Coose, TSA Federal Security Director for Idaho. “Gun owners need to be responsible when they fly and ensure that they do the right thing by either leaving their weapon at home, or packing it in their checked luggage and properly declaring it to the airlines. Otherwise, they may find themselves missing their flight while dealing with police and other security officials.”

The two firearms seized at the Boise Airport Sunday bring the 2017 total to 14. A total of 18 were found in 2016.

This is the second time this year TSA officers found two firearms in one day at the security checkpoint in Boise.

Nationwide, TSA officers have found more than 1,500 firearms at security checkpoints this year.

Firearms, ammunition, firearm parts and realistic replicas of firearms are prohibited in carry-on baggage. However, these items can be transported in checked baggage if the traveler declares them to the airline during the check-in process.

Firearms in checked baggage must be unloaded and stored in a locked, hard-sided container.

Violators could face state or local charges. Additionally, TSA could levy a civil penalty of up to $7,500 for bringing a dangerous weapon like a firearm to the checkpoint.

TSA reminds passengers to be aware of the contents of their carry-on bag prior to coming to the security checkpoint.
