The TSA is warning travelers about a seasonal glitch that could cause airport security delays

The TSA warns that Halloween travelers can face delays and challenges at airports with costumes, heavy metal accessories and carry-ons.

Halloween travelers warned about costume mistakes that could cut through airport security

Keith Jeffries, a former director of federal security in Los Angeles, says festive clothing and accessories can complicate screening travelers at airports.

Travelers planning to fly in costume this Halloween may face unexpected hurdles at airport security.

According to the agency's website, while the clothes themselves are usually allowed, some accessories, masks, special makeup and metal parts can cause problems at TSA checkpoints.

Passengers wearing elaborate face coverings or heavy makeup may be asked to remove it if their identity is not verified during screening.

"If you're wearing Halloween-style makeup and it can't recognize you, it creates challenges," she said.

Clothing items packed in luggage can also raise security concerns, especially when they resemble weapons or other prohibited items.

Similar explosives, including fake bombs and grenades, are not allowed in carry-on or checked baggage, according to TSA guidelines.

Experts say that weapons such as fake knives, swords, guns and pitchforks should also be kept out of handbags. Depending on the type of goods, some checked bags may be allowed.

Jeffries recalls seeing similar issues during his 20 years at TSA, including travelers trying to bring replicas of Lucille, the barbed-wire baseball bat featured in "The Walking Dead," through security.

"Of course, it can't go through the checkpoint," he said, noting that it could be put in checked bags.

Jeffries said heavy metal clothing could cause another headache by activating screening equipment, potentially leading to more screening.

"It creates all kinds of challenges and slows down the whole process," he said.

Passengers packing cosmetics must also follow TSA's standard liquid restrictions.

According to the TSA, liquid cosmetics in carry-on items must generally be in containers of 3.4 ounces or less, while larger amounts must be placed in checked bags.

For travelers bringing more elaborate clothing or accessories, Jeffries recommends packing them instead of wearing them through security.

"My biggest piece of advice is to put all that stuff in your checked bag, even if you don't normally like to check a bag," he said.

"Put your clothes on, go where you're going and have fun," Jeffries said.
