London Heathrow Airport began as a humble airfield in 1929, later repurposed by the British government during World War II for military use. It officially opened to civilian air traffic in 1946, with a makeshift terminal housed in former military marquees. Over the next several decades, Heathrow grew rapidly, becoming the UK’s largest and busiest airport. Major developments included the opening of Terminal 1 in 1968, which signaled the start of a modern airport era, and later Terminal 5 in 2008, a symbol of cutting-edge design and capacity.

Heathrow has long served as Britain’s primary international gateway, playing a crucial role in shaping global aviation routes and connecting the world to Europe.
