A 48 hour tube strike means passengers are struggling to get to London airports from today.
In addition to the Tube services, Heathrow said that its Heathrow Express and Connect overland services to and from the airport are also being disrupted.
A statement on the website said: “Due to the planned London Underground strikes, our trains are likely to be busier than usual so please allow more time for your journey.”
The Piccadilly Line is only operating between Acton Town and the Heathrow’s Terminals 1,2 and 3 and there is no Heathrow Connect service.
National Express is operating additional services between Heathrow and Victoria coach station during the strike period, however the coach operator has warned that some services may be subject to delays due to the impact of the strike.
All train services on the Gatwick Express are currently running normally, as are railways services to London City, however passengers are advised to leave extra time for their journeys.
The RMT union is striking over London Underground’s plans to close ticket offices and cut 960 jobs. It has warned that if the dispute is not resolved, then a second 72-hour strike, is planned to begin at 9pm on 5th May.
