• It’s the world’s third-busiest airport in terms of takeoffs and landings. It’s the world’s sixth-busiest if you’re counting passengers.
• The airport covers 29.8 square miles. That’s bigger than the island of Manhattan, which is just shy of 23 square miles.
• It has seven runways, plus room for an eighth. It can land four airplanes at once, something no other airport can do.
• And it’s served by 21 airlines that can take you to 173 destinations.
• Vendors are allowed to charge a maximum of 10 percent more than similar items cost outside the airport. The add-on compensates for the higher costs of airport operations.
