The next time your flight is delayed, instead of shaking your fists at the responsible airline, use your extra-long layover to appreciate all that goes on behind-the-scenes at the airport. Here are 15 amazing facts to help you pass the time.
1. What’s the busiest airport in the world? Well, depends on what you mean by “busy.” If you’re going by most passengers per year, that title would go to Chicago’s O’Hare, which overtook Atlanta’s Hartsfield-Jackson as the world’s busiest in 2014. O’Hare also boasts the most take-offs and landings. When it comes to international travelers, Dubai takes the cake. Meanwhile, Hong Kong International Airport handles the most cargo traffic annually.
2. You can find the world's tallest air traffic control tower at Thailand’s New Bangkok International Airport. At 434 feet, it’s as tall as a 40-story skyscraper.
3. King Fahd International Airport in Dammam, Saudi Arabia, is massive. It sits on 192,000 acres of land—that’s bigger than the entire country of Bahrain.
4. Which is the smallest airport in the world? Look to the Caribbean island of Saba, whose Juancho E. Yrausquin Airport has the shortest commercial runway on Earth. At 1,299 feet long, it’s way too short for jets, and airlines must get special permission to fly there.
