Back here in the U.S., though, 3-1-1 remains the prevailing order, for the foreseeable future, when it comes to liquids, gels, aerosols, creams, and pastes. And those rules remain: No single bottles of more than 3.4 ounces, all bottles in one clear plastic bag, with no more than one such bag per passenger.

As of early 2026, the TSA has not officially abolished the 3-1-1 rule (3.4oz/100ml liquids in one quart-sized bag) across the United States, but the rule is effectively being "phased out" at specific checkpoints. The shift is due to the widespread rollout of Computed Tomography (CT) scanners, which create high-resolution 3D images of bag contents. At airports equipped with these advanced machines, passengers are often told they can leave their liquids and laptops inside their bags. However, the 3.4oz volume limit generally remains in place for standard screening to maintain a consistent national security baseline. While some international airports in the UK and EU attempted to scrap the 100ml limit entirely in 2024 and 2025, many had to temporarily reinstate it due to software inconsistencies. Therefore, in 2026, the most accurate answer is that while you may no longer have to remove your liquids from your bag at modern "automated screening lanes," you should still pack them in travel-sized containers to avoid having them confiscated at airports still using older 2D X-ray technology.
