Heathrow flooding chaos as airport tells passengers 'don't travel by road' to two terminals

In a statement issued on Saturday morning, the airport urged people to allow extra time for their flights.

It said: “Flooding in the central terminal area has resulted in on-going road closures restricting access to Terminals 2 and 3.

“Passengers travelling to or from either of these terminals today must not travel by road.

“Passengers are strongly advised to use Heathrow Express, Elizabeth Line and Piccadilly Line rail services where possible.

“Any passengers that must travel by car must use Park and Ride, head to Terminals 4 or 5 and take free rail services from there, or change at local rail stations. Please allow extra time for your journey.

“Our teams are working to resolve the situation as quickly as possible, we apologise for any disruption caused.”

The disruption comes during one of the busiest periods for the airport as millions head overseas during the school holidays.

The airport saw its busiest day of the year on July 19, when 267,000 passengers passed through the hub.
