Due to a planned demonstration on Saturday 31st May, there will be some road closures and changes to bus routes around the eastern side of Heathrow Airport.
Customers are advised to allow extra time to travel to Heathrow on this day or consider using alternative modes of transport.
Please note that the main route into Terminal 5, via the M25, will be open as normal.
Access to Terminals 1, 2 and 3 from the M4 should be unaffected as will access to Terminal 4 from the A30 Great South West Road. Traffic on these roads may be heavier than usual.
