Piccadilly Line cut at Heathrow Terminal 5 due to security alert
22 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Travellers heading to or from Heathrow Terminal 5 by Tube should be aware that the Piccadilly Line is suspended between Heathrow Terminals 2 & 3 and Terminal 5 following a security alert at the terminal. The rest of the Piccadilly Line is running a good service.
For Chiswick residents catching flights from Terminal 5, the most reliable alternative at present is to take the Piccadilly Line to Heathrow Terminals 2 & 3 and then use the free inter-terminal transfer bus, which runs a regular shuttle between terminals. Alternatively, a taxi or ride-hailing service directly to Terminal 5 from Chiswick will avoid the disruption entirely — worth factoring in if you have a tight check-in window.
TfL has not confirmed how long the suspension will last. Check the latest status on the TfL website before you travel, and allow extra time if your flight is this morning. Airport authorities have not issued any further public statement at the time of publication.
Heathrow-bound travellers have faced several Piccadilly Line disruptions in recent weeks; building in contingency time remains sensible advice.
