While the largest and most well-known airport in London is undoubtedly London Heathrow Airport (LHR), the city’s second-most-important airport continues to grow rapidly and more and more passengers pass through the facility’s doors each year. Located in West Sussex about 30 miles south of Central London, Gatwick is, year-over-year, the second-busiest airport in the United Kingdom by passenger traffic and often ranks as one of the ten busiest in Europe.
