Rail and road access to Heathrow Airport has been severely impacted by flooding. Initially, disruptions were reported on rail services connecting central London to the airport, specifically affecting the Elizabeth line and Heathrow Express due to flooding between Hayes & Harlington and the airport terminals. This included a tunnel closure for safety reasons.

As the situation progressed, flooding expanded to the central terminal area, resulting in road closures that restricted access to Terminals 2 and 3. Heathrow issued warnings advising passengers to avoid road travel to these terminals and instead utilize rail services such as the Piccadilly Line, Elizabeth Line, or Heathrow Express. For those traveling by car, the airport recommended using Park and Ride services at Terminals 4 or 5.
