Heathrow Airport Lifts Long-Standing Restrictions on Liquids and Electronics
Published: 2026/01/25 22:58:34
In a significant move to streamline the passenger experience, Heathrow Airport has fully implemented new security scanners allowing passengers to carry liquids up to two liters and keep laptops and larger electronic devices in their hand luggage during security checks. this marks a major shift from the restrictions imposed in 2006, and positions Heathrow as a global leader in airport security innovation.
The End of the 100ml Rule
For nearly two decades,travelers have been required to place liquids in small,clear plastic bags to pass thru airport security.This rule, introduced following a foiled terrorist plot involving liquid explosives in 2006, has been a source of frustration for many passengers. Heathrow’s new technology eliminates this requirement, allowing for greater convenience and reducing the time spent in security lines. Passengers can now bring larger volumes of liquids, toiletries, and other items in their carry-on bags, provided they are contained within containers of up to two liters.
Advanced Security Technology: A Deeper Look
The change is made possible by the deployment of advanced Computed tomography (CT) scanners. These scanners provide highly detailed 3D images of the contents of bags, allowing security personnel to identify potential threats more effectively and efficiently. Heathrow Airport explains that this technology offers a more detailed view than conventional X-ray machines, reducing the need for manual bag checks and minimizing delays.
Rollout Across the UK and Beyond
Heathrow isn’t the first UK airport to adopt this technology. Gatwick, Birmingham, Bristol, and Edinburgh have already implemented similar systems, also allowing liquids up to two liters.However,some airports,including London City,Luton,and Teesside,are still awaiting regulatory approval to lift the 100ml restriction. The phased rollout reflects the complexity of upgrading security infrastructure and obtaining the necessary certifications.
Environmental benefits
Beyond the convenience for passengers, the new
