For many travellers, the first glimpse of London begins through an aeroplane window. As the plane descends through the clouds, the vast sprawl of the city appears below — rivers, parks, neighbourhoods and the unmistakable energy of one of the world’s busiest capitals.
London is served by several major airports, making it one of the most connected cities on the planet. Whether you’re arriving from Europe, North America, Asia or elsewhere, there’s a good chance your journey will pass through one of the city’s aviation hubs. Understanding how London airports work can make your arrival much smoother, especially when planning transfers into the city centre.
Each airport has its own advantages. Some focus on long-haul international travel, while others specialise in budget airlines or business routes. Knowing which airport you’re flying into — and how far it is from central London — helps you plan transport, accommodation and travel time far more effectively.
