Join the service at Terminal 5 (typically bound for Cockfosters) and Green Park will be the 19th station you arrive at.
It is the station immediately following Hyde Park Corner.
About 30 minutes
walk
Take the London Underground - the Piccadilly line operates from the underground station at terminal 3 directly to Green Park underground station, the journey takes around 45 minutes.
Two ways 1. Piccadilly Line Jubille line south bound from Bond Street to Green Park Change to Piccadilly line for Heathrow Terminal 4 2. Heathrow Express Bond Street to Oxford Circus on central line or walk. Oxford Street change to Bakerloo line northbound. Change at Paddington for Heathrow Express train.
Northbound
No. You need to get a Piccadilly line tube from any of Heathrow's terminals to Green Park, then you need to change onto a Victoria line train to Kings Cross/St. Pancras. From King's Cross train station you can get an East Coast main line train to Durham.
Piccadilly line from Heathrow Airport to Green Park. Change for the Jubilee line Northbound to Swiss Cottage. The London Underground (subway) only goes as far as Swiss Cottage station and the friendly London Underground staff at Swiss Cottage can give you directions for the rest of your journey.
45 minutes on the Piccadilly line
Grand Central Station & Terminal are located at East 42nd Street between Park and Lexington Avenues. Grand Central Station is the subway station, where you can catch the 4-5-6 (the dark green line, aka the Lexington Avenue Line) or the S shuttle train to Times Square. Grand Central Terminal is the railroad terminal, for trains that are not part of the New York City subway system (like MetroNorth commuter trains).
Either take a cab or the tube (underground train)to central London and a bus or short cab ride from there. A cab is very expensive. The quickest (but more expensive) way by public transport is to take the Heathrow Express train (station is between terminals 1 & 2) to London Paddington station. From there, it's probably easiest by cab as it's an awkward tube journey. Slower but cheaper is to take the Piccadilly Line to Green Park (about 50 mins running time) then walk a short distance along Piccadilly towards Piccadilly Circus, and Old Bond St is on the left. Do the opposite for a journey from Heathrow to Bond Street.
The airport code for T. F. Green Airport is PVD.
You can take the underground line U3 (direction Simmering) and get to the Landstraße/Wien Mitte station. You can follow the green CAT signs with a small plane on it. The CAT (city airport train) will take you to Vienna airport in a few minutes.

There is no simple route between these two airports. The best that I can find is as follows: Take the DLR (Docklands Light Railway) from London City Airport stop to Canning Town station and transfer on to the Jubilee line tube (underground) station to Green Park. At Green Park, change to the Piccadilly line which will take you to Heathrow (all terminals). If you have four or five people travelling together, it might be more affordable to take a taxi.
