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.

Previous Airspace Change Proposals

Heathrow previously initiated a number of Airspace Change Proposals (ACPs) to address specific airspace issues or constraints. However, these were paused in 2020 so the airport could prioritise recovery from the COVID-19 pandemic.


The airspace modernisation programme will require the wholesale redesign of flight paths to and from Heathrow’s two existing runways. Requirements associated with previous ACPs will be incorporated into the new airspace design where appropriate.
