London is widely recognized as the city with the most "major" airports serving its metropolitan area. In 2026, the London system consists of six primary airports: Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN), City (LCY), and Southend (SEN). This multi-airport system provides a high-value range of options, from the global hub of Heathrow to the low-cost bases of Stansted and Luton. While New York City is a close second with three "primary" airports (JFK, LGA, EWR) and several regional ones like Islip and White Plains, London’s six are all significantly integrated into the city's international transit network. For travelers, this "multi-hub" reality means you must be extra careful to check your departure and arrival codes; a peer-to-peer "fail" is arriving at Heathrow for a flight that actually departs from Gatwick, which are located nearly 40 miles apart. Having so many airports makes London the highest-value city for "competitive airfares" in Europe, as dozens of airlines fight for slots across the six distinct gateways.
