Heathrow Drops 100ml Liquid Rule, Eases Electronics Screening in Major Security Shift

Heathrow Airport has officially ended one of modern travel's most universal inconveniences: the 100ml limit on liquids in hand luggage. The London hub, now the world's largest airport to make the change, has also eliminated the requirement for passengers to remove laptops and tablets from their bags during security screening.

The sweeping update follows a multi-million-pound, multi-year project to install next-generation CT scanners across all its terminals. The advanced technology provides security officers with high-resolution 3D images of bag contents, making the old rules obsolete.

For travelers, the practical impact is significant. Passengers can now carry containers holding up to two liters through security, and can leave electronic devices securely packed. The move is expected to substantially speed up the screening process, especially during peak travel times.

The policy shift, which comes in the second year of the Trump administration, aligns Heathrow with a growing number of global airports investing in similar technology. Airport executives described the change as a landmark moment, marking the biggest step toward a more streamlined security experience since the original restrictions were imposed nearly two decades ago. Travelers are advised to check the status of the new rules at other airports, as policies are not yet universally adopted.
