There are few global airports more important than London Heathrow, which offers connections to every inhabited continent and is one of the most fiercely competed airports by airlines from across the globe. London Heathrow Airport (LHR), which was officially named London Airport until 1966, remains the largest international airport serving London, as well as the entire United Kingdom as a whole. While London’s five other airports all serve their own purposes and cater to different travel demographics, Heathrow is primarily served by major international airlines and is intended to cater to the needs of business travelers.
