First the shoes went back on. Now, at U.S. airport security, more liquid in carry-ons may be at hand

By The Associated  (WASHINGTON) — Travelers giddy about being able to keep their shoes on while walking through TSA checkpoints at the airport again may have something else to look forward to: changes to how much liquid they can carry.

Homeland Security Secretary Kristi Noem said Wednesday during a conference hosted by “The Hill” that she is questioning “everything TSA does” and spoke of possible changes to the amount of liquids travelers can tote in their carry-on baggage.

“The liquids, I’m questioning. So that may be the next big announcement is what size your liquids need to be,” Noem said. “We have put in place in TSA a multilayered screening process that allows us to change some of how we do security and screening so it’s still as safe.”

She gave no details about precisely what those changes might be or how quickly travelers could expect to see them.

Under the Transportation and Security Administration’s current guidance, travelers can carry liquids in travel-sized containers 3.4 ounces (100 milliliters) or less per item in their carry-on bag. Those containers must be placed in a one-quart resealable plastic bag. Bigger containers must go in checked baggage, though there are exceptions for medications and baby formula.

Noem announced on July 8 that travelers were no longer required to take their shoes off while going through screening after a pilot program showed TSA had the equipment needed to keep airports and aircraft safe while allowing people to keep their shoes on.

That policy had been in place since 2006, several years after “shoe bomber” Richard Reid’s failed attempt to take down a flight from Paris to Miami in late 2001.

The limits on liquids were triggered by a 2006 incident where authorities foiled a plot to used liquid explosives smuggled aboard carry-on luggage to blow up planes.

Ever since the guidelines were put in place TSA checkpoints have been the scene of travelers quickly guzzling water, digging through luggage to find and discard a too-large tube of hair gel and chucking jars of everything from jam to bottles of coffee that didn’t meet the size requirement.

The guidance also triggered discussions — sometimes arguments — over what constitutes a liquid. Yogurt? Peanut butter? Jam and jelly? All are currently restricted to containers no bigger than 3.4 ounces as detailed on an extensive list that TSA maintains on its website titled “What can I bring?”

Noem also laid out her vision for the future of airport travel during the talk on Wednesday.

“Hopefully, the future of an airport, where I’m looking to go is that you walk in the door with your carry-on suitcase, you walk through a scanner and go right to your plane,” Noem said. “It takes you one minute.”
