London airports serve very different parts of the city, and knowing which one connects best to your neighborhood can save you real time and money on every trip.
Heathrow: the west London gateway
Heathrow sits about 14 miles west of central London. It handled more than 84 million passengers in 2025, making it the UK’s busiest airport and a major global hub. That scale means excellent connections, but also large crowds and long terminal walks.
If you stay in West London, Kensington, Hammersmith, or Paddington, Heathrow is almost always the right choice. The Heathrow Express reaches Paddington in 15 minutes with a direct service. The Piccadilly line on the London Underground connects all terminals to central London in 45 to 60 minutes. The Elizabeth line is a third option, useful if you travel toward the City or east.
Heathrow serves 214 destinations across 84 countries, so it handles most long-haul routes. If you fly to North America, Asia, or the Middle East, Heathrow is likely your only practical option from London.
Gatwick: the south London choice
Gatwick sits south of London, about 30 miles from the center. It is the second busiest of the London airports, and it works very well for travelers staying in South London, Brixton, Clapham, Croydon, or anywhere along the Victoria line corridor.
The Gatwick Express connects the airport to London Victoria station. Trains depart twice per hour and the journey takes 30 minutes. Southern and Thameslink trains also run to other central stations, which is useful if Victoria is not close to your accommodation.
Gatwick is a strong base for budget carriers and European routes. If your flight offers a choice between Heathrow and Gatwick, and you stay south of the Thames, choose Gatwick without hesitation.
Stansted and Luton: budget airports for north and east travelers
Stansted and Luton are the two London airports most associated with budget airlines. Both sit north of the city, and both require a longer journey to central London, but neither is as difficult as its reputation suggests.
The Stansted Express connects Stansted Airport to Liverpool Street station in central London. Trains depart every 15 to 30 minutes with an average journey time of 45 minutes. Stansted suits travelers staying in Shoreditch, Bethnal Green, Islington, or anywhere near Liverpool Street. Stansted is situated outside Transport for London zones, so you pay a separate fare on top of any Tube journey.
Luton is the furthest from central London of all 5 airports. It is a popular choice for budget travelers because it houses low-cost carriers such as Wizz Air, EasyJet, and Ryanair. From Luton Airport Parkway station, the Luton DART (Direct Air-Rail Transit) covers the 4-minute journey to the terminal. Trains run between central London and Luton Airport Parkway up to 4 times per hour. Travelers staying near St Pancras, Kings Cross, or north London will find Luton more convenient than those in other parts of the city.
Expert perspective on London airports
Choosing between London airports is not just about which one your airline uses. It is about where you arrive in the city afterward. Many travelers book the cheapest ticket and then discover a 90-minute Tube journey at the other end, which removes any savings they made on the fare. The key question is always: how far is this airport from my front door, not from some abstract idea of central London? A traveler in Canary Wharf will reach London City Airport faster than they reach Paddington for Heathrow. A traveler in Camden will reach St Pancras for a Luton train in 10 minutes. Transport in London is excellent, but it rewards people who plan it in advance. The airport that fits your neighborhood is always the right airport.

London City Airport: the best-kept secret for east and central travelers
London City Airport is located in the Royal Docks of the Borough of Newham, 6 miles east of the City of London and 3 miles east of Canary Wharf. It is compact, efficient, and often overlooked by visitors who default to Heathrow.
Its proximity to Canary Wharf makes it very accessible and popular with business travelers. The airport is relatively small and efficient, meaning shorter check-in times and faster arrivals processing. The Docklands Light Railway (DLR) connects the airport to Bank and Tower Gateway stations as well as Stratford International. It takes about 20 minutes to reach Bank station.
London City was the airport with the highest proportion of passengers from Greater London, at 77 per cent. If you stay in the City, Canary Wharf, Greenwich, Stratford, or anywhere on the DLR network, London City Airport should be your first check before you book any flight.
Conclusion: match the airport to your postcode
