Landing at some of the world’s biggest airports in the world is a journey on its own. A microcosm of humankind and international influences, these aviation meccas are seemingly void of uniform times and cultures. Instead, passengers live by their own set of rules, infusing the shared space with diversity and a reprieve from societal expectations.
Naturally, a long layover seldom makes your travel itinerary by choice. And whilst, you could spend the hours sleeping off jet lag in the nearest luxury lounge—we say, why not embrace it?
Ready for take off? We’re off to a fly start with a list of the largest airports in the world by size. Spoiler: By land area, Dubai International (UAE) is large but don’t crack the global top 10. However, in terms of passenger traffic, it ranks among the busiest airports worldwide.
