Size isn’t everything, but when it comes to airports, it really does kick start your vacation before even jumping on the plane. So, you’re probably wondering “what is the biggest airport in the world?” Let’s find out!

Since November 1999, the King Fahd Airport in Dammam, Saudi Arabia, has taken the top spot for the biggest airport in the world.
The airport was named after the former King of Saudi Arabia, Fahd Ibn Abdulaziz, and spans a whopping 299.6 square miles!
King Fahd International Airport sees over 10 million passengers arrive and depart from its terminals every year, with 37 airlines operating flights in and out to 43 destinations.

Currently, you can travel from the Denver International Airport to 215 destinations worldwide, and traveling between the airport’s 3 terminals requires the use of the airport’s automated train system.
As the DEN airport is located near the Rocky Mountains, you can catch incredible mountain views from the west end of all 3 concourse terminals.
3. Dallas/Fort Worth International Airport (DFW): 26.9 sq. mi. | 69.6 sq. km.
Another airport in America that is larger than the island of Manhattan is the Dallas/Fort Worth International Airport. DFW even has its own ZIP code and emergency services, so it is basically considered a city. Crazy, right?
