London City Airport (LCY) is "busy" in terms of its efficiency and the frequency of flights, but it is much smaller in scale than London’s mega-hubs like Heathrow or Gatwick. In 2024 and 2025, the airport handled approximately 3.4 to 3.6 million passengers annually. While this is a fraction of Heathrow's 80 million, London City is exceptionally dense; because it has a single runway and is located just miles from the Canary Wharf financial district, it serves a constant stream of business travelers. In late 2024, the UK government approved an increase in the airport's passenger cap from 6.5 million to 9 million, indicating plans for significant growth. For a traveler, it often feels busier than its numbers suggest because the terminal is compact, designed for 20-minute "curb-to-gate" transits. It is the preferred choice for those working in the City of London due to its proximity and the sheer number of short-haul European business routes operating daily.
