Once you're in London, the cheapest and easiest way to get around the city is with an Oyster Card. It is valid across all travel zones and automatically calculates the best value fare for all the journeys you make in a single day. It can be used on buses, Tube trains, trams, DLR, London Overground and most National Rail services in London. You can buy the card online, pre-loaded with credit, before you go to London (the card can now be sent to 58 countries around the world.)
Heathrow (LHR) is one of the world’s busiest airports, handling more international passengers than any other. The airport is located 15 miles (24km) to the west of central London. Upon arrival, the Heathrow Express offers the quickest – but also most expensive – method of getting into central London. Trains leave Heathrow airport from approximately 0500 until 2330. Standard fares are £16.50 single and £32 return. The Heathrow Express calls at the two stations serving the airport, one for Terminal 1-3 and the other for Terminal 4. Journey time is 15-20 minutes and the service is non-stop to Paddington station.
London Gatwick (LGW) is the second largest airport in the UK after Heathrow. It is the seventh busiest international airport in the world, handling 30 million passengers every year. Gatwick airport is located 28 miles (45km) south of London. The two terminals, North and South, are linked by an efficient monorail service, with a journey time of two minutes. Once again, the Gatwick Express is the quickest way into central London. Trains leave Gatwick Airport from 0435 to 0135. The station is in the South Terminal and linked to other parts by escalators and lifts. At peak times trains run every 15 minutes (from 0605 to 2005) and roughly every 30 minutes off-peak. Standard fares are £17.90 single and £30.80 return. Journey time is 30 minutes and the service is non-stop to Victoria station.
London Stansted (STN) is London's third international gateway and one of the fastest growing airports in Europe. It is home to many of the UK's low-cost airlines, serving mostly European and Mediterranean destinations. The airport is located 35 miles (56km) to the North-East of London.
The London Underground, or 'Tube' as it is commonly known, is the oldest underground system in the world. An attraction in its own right, the London Underground is one of the best ways to get around the city. The most useful lines for Paddington are the Circle and District lines (yellow , green).
