Heathrow finally scraps the 100ml liquid rule as £1bn scanners let laptops stay in bags
Heathrow has installed new CT scanners in all security lanes, letting passengers keep liquids and large electronics in their carry-on bags. The £1 billion upgrade removes the 100ml liquid limit for Heathrow departures, but UK guidance warns that rules still vary at other airports. Travelers may face different restrictions on return or connecting flights.
