As of early 2026, several major airports have officially scrapped the restrictive 100ml liquid rule thanks to the rollout of advanced C3-grade Computed Tomography (CT) scanners. In the United Kingdom, London City (LCY) and Teesside International (MME) were the pioneers, followed by a phased rollout at larger hubs like London Heathrow (LHR) and Gatwick (LGW), though travelers should still check specific terminal readiness. Internationally, Shannon (SNN) and Donegal (CFN) in Ireland have removed the limit, allowing liquids up to 2 liters. Amsterdam Schiphol (AMS) in the Netherlands and Leonardo da Vinci–Fiumicino (FCO) in Rome have also modernized their security checkpoints. These scanners create a high-resolution 3D 360-degree map of the bag's contents, allowing security to identify explosives without requiring passengers to remove liquids or laptops. While the technology is expanding, many airports worldwide still enforce the 100ml limit, so it remains essential to verify the specific rules for every leg of your journey to avoid having items confiscated at transit points.
