Heathrow's Security Revolution: The 100ml Liquid Limit Is Officially History

A long-standing frustration for air travelers has ended at London's Heathrow Airport. As of this month, the strict 100ml limit on liquids in hand luggage is no longer in force, a change made possible by a major, airport-wide upgrade to next-generation security scanners.

The new computed tomography (CT) equipment, now fully operational across all Heathrow terminals, provides security staff with high-resolution 3D images of cabin bags. This allows for a far more detailed analysis of a bag's contents, eliminating the need for passengers to remove laptops and tablets from their carry-ons. More significantly, it renders the old liquid rules obsolete.

Travelers can now carry containers holding up to two liters through security, and the requirement to present all liquids in a single, clear plastic bag has been scrapped. The policy shift, which follows successful trials and a government mandate, brings Heathrow in line with other major global hubs that have adopted the technology.

"This is the most significant change to airport security in nearly two decades," said a Heathrow spokesperson. "It means a simpler, faster preparation process at home and a much smoother experience at the airport." The change is expected to significantly reduce queue times at security checkpoints, a welcome development as passenger numbers continue to recover. While the new rules are now active, officials advise passengers to always check the specific requirements of their destination airport, as older regulations may still apply elsewhere.
