Travelers in the U.S. could one day enjoy one less restriction when going through airport security. Restrictions on the size of liquids allowed in carry-on luggage could be revised, paving the way for full-size items like shampoos and lotions to make it past the checkpoint hassle-free.
Since the post-9/11 overhaul of aviation security, travelers have faced strict liquid regulations. The current "3-1-1 rule" limits liquids, gels and aerosols in carry-ons to 3.4-ounce containers, and all must fit in a single quart-sized bag. While these measures aim to enhance safety, they’ve certainly caused plenty of pre-trip packing headaches.
What liquid carry-on rules could TSA change?
Rampant speculation hints that TSA may one day ease these restrictions thanks to advancements in airport security technology. The adoption of computed tomography (CT) scanners—machines capable of creating detailed 3D images—could allow TSA agents to better identify potential threats while permitting passengers to carry full-sized liquids.
Though the potential changes wouldn’t eliminate security screening altogether, they promise a smoother process for passengers juggling essential items and toiletries.
While no specific timeline has been announced for these changes, and a lifting of restrictions may not be in the works for years to come, the implementation of CT scanner technology is gaining momentum in airports worldwide. Travelers should keep an eye on updates from the TSA and pack their bags accordingly. Until then, those tiny travel-sized bottles remain the golden rule for carry-on liquids.
