Transportation Security Administration officials report that an airline passenger last week tried to smuggle three knives through a check point at Honolulu Airport by hiding them in a thermos.

The three knives were among the prohibited items airline passengers tried to sneak through airport security check points last week, the TSA said in its weekly report.

TSA officials said 30 firearms were discovered at checkpoints around the country last week – 25 of those firearms were loaded and 13 had rounds chambered. 

In Honolulu, three knives were discovered in a passenger’s thermos at Honolulu Airport. The passenger had traveled through the checkpoint once and was permitted to take the knives outside of the checkpoint area to check them in his baggage. Instead, he attempted to sneak them through in a thermos, the TSA reported.

Officials did not say when the incident occurred or if any charges were filed. Violators could face a penalty as high as $7,500.00, the TSA said.
