It takes time and money to reach London's airports; in fact it can be more expensive to get to the airport than the cost of the flight itself. London has 5 different airports, only one of which is actually in the centre of London - City Airport. City Airport deals mostly with internal domestic flights. The other four airports are Gatwick, Heathrow, Stansted, and Luton are located on the outskirts of London. The Eurostar train can also provide access to continental Europe. The main terminal for the Eurostar is at St. Pancras International, London, but there is a more nearby station at Ebbsfleet International.
