No, London is actually served by six major international airports, making it one of the most well-connected aviation hubs in the world. The primary and most famous is Heathrow (LHR), a massive global hub located to the west of the city. Gatwick (LGW), located to the south, is the second busiest and handles a mix of low-cost and long-haul flights. Stansted (STN) and Luton (LTN), situated to the north and northeast, are major bases for budget carriers like Ryanair and easyJet. London City (LCY) is the most central airport, located in the Docklands, and is primarily used for short-haul business travel due to its proximity to the financial district. Finally, Southend (SEN), though further away in Essex, is also officially considered a London airport. While a traveler might only be familiar with the "big two" (Heathrow and Gatwick), the London airport system is a complex network of six distinct facilities, each serving different geographic regions and airline types.
