While we're on the subject, anyone travelling to/from London may want to consider taking the Airbus from Stratford rather than the Stansted Express. The Airbus only takes about ten minutes more but costs just £6. It operates every 30 minutes 24/7, and Stratford serves the Central and Jubilee Lines, Docklands Light Railway and National Rail Services. Go to

Other Airbus services operate to/from Golders Green, Marble Arch and Victoria. After midnight some Airbus's also serve Liverpool Street.
