Heathrow Airport has warned passengers to expect disruption after flooding restricted road access to Terminals 2 and 3, prompting travellers to be advised to use public transport instead of cars.
The disruption comes during the summer school holidays, traditionally one of the busiest periods of the year for the UK’s largest airport.
Flooding Restricts Access to Heathrow Terminals 2 and 3
Floodwater in Heathrow’s central terminal area has affected access to both Terminals 2 and 3.
According to the airport, passengers attempting to travel to or from the two terminals are currently unable to do so by road.
Travellers have instead been advised to use rail and London Underground services and to avoid travelling to the affected terminals by car while the restrictions remain in place.
Heathrow said its teams were working to deal with the flooding and restore normal access.
“Our teams are working to resolve the situation as quickly as possible, we apologise for any disruption caused,” the airport said early on Saturday.
Passengers Advised to Use Rail and Tube Services
The restrictions could affect passengers being dropped off or collected from Terminals 2 and 3, as well as other road journeys into Heathrow’s central terminal area.
With road access affected, passengers have been encouraged to consider public transport options. Heathrow is served by the Piccadilly line, Elizabeth line and Heathrow Express, providing connections between the airport and central London as well as links to the wider rail network.
Passengers travelling on Saturday are advised to allow additional time for their journeys and check the latest transport information before setting off.
Flooding Hits Heathrow During Busy Summer Holiday Period
The disruption has occurred at a particularly busy point in Heathrow’s annual travel calendar, with large numbers of families travelling during the school summer holidays.
Heathrow said 19 July had been its busiest day of the year so far, coinciding with the start of the summer break for many schools across England.
Around 267,000 passengers passed through the airport on that day, highlighting the pressure on Heathrow’s terminals and transport connections during the peak summer season.
Any restrictions affecting access to major terminals can therefore have a significant impact on passenger journeys, particularly during weekends and holiday periods.
Heathrow Has Faced Recent Transport Disruption
The flooding follows another recent transport problem affecting passengers travelling to and from Heathrow.
Rail services were disrupted after a water leak led to the closure of a tunnel, causing difficulties for some passengers using public transport to reach the airport.
The latest incident involves road access to the central terminal area rather than airport operations more broadly, with Heathrow directing passengers towards rail and Tube services while teams work to resolve the flooding.
Travellers Urged to Check Before Heading to Heathrow
Passengers with flights departing from Terminals 2 or 3 should check information from Heathrow, their airline and public transport operators before beginning their journey.
Those planning to travel by car, including passengers expecting to be dropped off or collected, may need to make alternative arrangements while road restrictions remain in place.
Heathrow has not indicated how long the disruption will last, but airport teams are working to resolve the situation as quickly as possible.
For travellers using Britain’s busiest airport during the summer holiday rush, checking transport conditions and allowing extra journey time could help reduce the impact of the ongoing disruption.
