London: Free Public Bus from Heathrow Airport to Bath Road

I am currently attending a workshop in London and the venue is along Bath Road near Heathrow Airport, which is where most of the major hotels. The good thing about the venue is that those flying in from different countries could just take the red, public bus coming to the hotel, free of charge. Heathrow has a "free travel zone" area which means the you could take the public buses for free, as long as they are within this zone, which are within the airport vicinity. However, you need to watch out not to go beyond the free travel zone, otherwise, you will need to have your Oyster Card to pay for the fare.  Click here to download  the free travel zone bus route.

You may board the public buses from the Central Bus Station.  If you are arriving at Terminals 1, 2 and 3, after getting past the immigration and after collecting your luggage, just follow the walk way leading to the bus station. If arriving at Terminal 4, use the Heathrow Connect Rail, which is free of charge, to go to Terminals 1,2 and 3.
