Heathrow finally scraps the 100ml liquid rule as £1bn scanners let laptops stay in bags
London, 23 Jan 2026, 13:22 GMT Heathrow, Europe’s busiest airport, announced on Friday that it has upgraded all security lanes with new computed tomography scanners. Passengers can now leave liquids, laptops, and tablets in their hand luggage during screening. The airport invested 1 billion pounds in the technology, which can scan liquid containers up to two litres, doing away with the 100ml limit set in 2006 after a liquid explosives plot was uncovered.
