As the only airport within the city limits of London, London City Airport will be the easiest to access from the city centre. City buses and the Docklands Light Railway connect the rest of the city and the London Underground to the airport. Heathrow Airport comes next, due to its direct connection with the London Underground, as well as the Heathrow Express train, which can reach the airport from Paddington Station in 15min. However, if you’re travelling from south London, Gatwick might be a good option, as it is 25 miles south of the city centre (there is also the 30min Gatwick Express train from Victoria Station).
