A plan to make airport security lines move a little quicker we’ll have to wait.
The 3.4-ounce rule on liquids will remain in place for now. The Transportation Security Administration said a scanner able to detect liquids up to two liters will not be implemented until at least 2040, largely due to the volume of passengers.
You’re not allowed to bring liquids in containers of more than 3.4 ounces on an airplane. That rule was supposed to change.
It isn’t anytime soon.
The rule that was put in place nearly 20 years ago as a temporary response to a failed terrorist attack in which the culprit tried to bring flammable explosives on a plane will go on. Some airports in Europe began utilizing a new Computed Tomography (CT) scanner in 2022 that is able to discern different types of liquids and their amounts.
Some airports, but not all.
The TSA in the United States has not fully adopted the new technology and has not planned to do so for more than a decade. So, the 3.4-ounce rule will live on until there is more uniformity. That is true even if some airports are using the new scanners.
"TSA is still deploying Computed Tomography units that are capable of screening larger sizes of liquids, however, the agency will not be able to change...for some time to come, because there are about 2,000 screening lanes in about 430 airports,” a TSA spokesperson said. "We are anticipating that it may not be until 2040 that we have CT units fully deployed across the nation and have the capability of changing the requirement across the system."
However, facial recognition use is in place.
