Heathrow Airport has issued a reminder to travellers ahead of an exceptionally busy summer period, urging them to empty reusable metal or double-walled water bottles before passing through security. The airport's official X account posted: "With over 100 touchless water stations at Heathrow, you're never too far from staying hydrated. Just remember to empty your reusable metal or double-walled water bottle before security, and top it up before you fly."
New Security Technology Allows Larger Liquids
Earlier this year, Heathrow scrapped the 100ml liquid restriction after completing the rollout of cutting-edge CT scanners. Travellers can now keep liquids in containers up to two litres inside their bags, and electronic devices like laptops can remain in luggage. Transparent plastic bags for liquids are no longer required.
Hundreds of thousands of passengers pass through Heathrow daily. The regulation change applies only to departures from Heathrow; travellers must verify baggage restrictions at the airports they are flying back from before boarding return flights to the UK.
Government Advises Checking Security Requirements
In January, a Department for Transport spokesperson said: "Heathrow is the latest UK airport to complete its rollout of next-generation security equipment for passengers, helping ensure security checks remain robust and can be completed smoothly. Airports are responsible for the installation and operation of security equipment. Passengers should continue to check security requirements with airports before they travel and come prepared with liquids in containers no larger than 100ml in hand baggage unless advised otherwise."
