London Underground strike action: 21-24 April

Due to planned strike action, there will be little to no service across all London Underground services, including the Piccadilly line to Heathrow, between 21 and 24 April 2026. 

 

Heathrow Express, Elizabeth line, and local bus services will run as normal on these days. Please plan your journey prior to travelling to Heathrow, and allow for extra time where necessary, as these services will be busier than normal.
