Overview
- Heathrow has completed installation of next‑generation CT scanners across Terminals 2–5, making it the largest airport globally to fully deploy the technology.
- Passengers can now leave laptops in their bags and carry liquids in containers up to 2 litres, with no clear plastic bags required; some vacuum or double‑walled bottles may need to be emptied.
- The CT system produces high‑resolution 3D images with automated threat detection, a setup Heathrow says can process thousands of passengers an hour while maintaining security standards.
- The airport estimates the change will eliminate nearly 16 million single‑use plastic bags each year and improve the flow through security lanes.
- The new policy applies only to departures from Heathrow, and rules at other UK and overseas airports remain mixed, with some still enforcing 100ml limits or operating transitional measures.
