London is home to six airports which, when combined, make up the busiest travel network in the world. Serving 14 domestic destinations and 396 international destinations, London remains king of the European travel hubs. Five of the six London airports provide flights to Rome: Heathrow, Gatwick, Stansted, Luton and London City.
Heathrow (LHR): As the UK’s busiest airport, you can rest assured there are plenty of frequent connections between Heathrow and Central London, including via the London Underground on the Piccadilly line around every 10 minutes.
Gatwick (LGW): Gatwick is the UK’s second-busiest airport, and can be reached via the Gatwick Express rail service in 30 minutes, running every 30 minutes from London Victoria station.
Stansted (STN): Stansted is located near the M11, northeast of London, and provides many cheap flights within Europe. The best way to get there is via the Stansted Express rail service, which runs every 15 to 30 minutes.
Luton (LTN): Like Stansted Airport, Luton also hosts many budget airlines. There are several convenient public transport routes to the airport from Central London running each day, including National Express, Thameslink and East Midlands Railway.
London City (LCY): London City Airport is the closest of these to the city centre, at 8.5 miles. To get there, you can take the DLR Underground service (running every 8 to 15 minutes) on the Jubilee line from Canning Town station.
Buses serve each airport, where transfers are easily made at major stations like Stratford. Buses are cheaper than rental cars and help connect to the final travel option. Rounding out the ways to travel to the airport are London’s train and tube systems. These similarly connect via numerous travel hubs, so it’s usually not too difficult to move between the different lines to get exactly where you need to go.
