There are three different modes of transportation available to you if you're travelling to the city centre of London from Luton airport (LTN), taxi, train and bus. Taking an airport taxi from Luton airport to the downtown area of London is the most convenient transfer option. The ride costs approximately €80 (£70) and will take around 1 hour and 15 minutes. The fastest way to reach the city centre of London is by train. Off-peak train tickets cost €16 (£14.20) and the journey only takes 35 minutes. A slightly cheaper alternative is the bus. Single tickets for the National Express or Green Line/Terravision bus cost €12 (£11), but the average travel time is 1 hour and 30 minutes, making it the slowest transfer option from Luton airport. Welcome Pickups offers meet and greet services and a friendly introduction to London at the same price as a regular taxi. Click here to see the cost.
