What Is the Biggest Airport in the World? Top 20 Largest & Busiest Airports Worldwide (with Pictures)

Ever wondered what the biggest airport in the world is? Today, we’re analyzing the question from a few different angles: largest by area, busiest by yearly passenger traffic, and finally biggest airports by continent. Put up those tray tables, because we’re taking off!

Biggest Airport in the World

Whether you’re going on a vacation or a business trip, it all begins in one place: the airport. 

The ever-growing demand for flights has resulted in cities creating super-sized airports that actually feel like cities themselves. Over 4 billion people travel by plane each year and, with numbers like this, airports have become some of the busiest places on Earth

As airports continue to expand and develop, so do their design features and facilities. Nowadays, not only can you catch a flight, but you can also shop designer brands, eat in spectacular restaurants, visit spas and more. Some have even gone as far as to have ice rinks, swimming pools, and aquariums!

To give you an idea of the world’s biggest airports, we’ve broken down the top 10 largest airports in the world by land size, as well as 10 more ranked by the number of passengers they see through their terminal gates each year.

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.

The airport is made up of 3 terminal buildings:

  • One six-story terminal for passengers;
  • Another for private airlines; and
  • The third and final terminal for the royal family of Saudi Arabia. 

The DMM airport has a plant nursery that supplies plants to the airport’s gardens, a separate shopping area, and a rooftop mosque that can accommodate up to 2,000 worshipers at a time. 

2. Denver International Airport (DEN): 52.4 sq. mi. | 135.7 sq. km.

2nd Largest Airport in the World - Denver International Airport

The Denver International Airport in Denver, Colorado measures in at around 52.4 square miles.

Even though it is significantly smaller than the King Fahd Airport (about 5.5 times smaller), the Denver International Airport is still 1.5 times the size of the island of Manhattan! It also has the longest public use runway in North America, itself running more than 3 miles long.

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.

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? 

The 26.9-square mile DFW airport was built halfway between the major cities of Dallas and Fort Worth (hence the name) and has 26 airlines flying to 260 destinations, making it one of few airports worldwide that fly to over 200 destinations. 

The Dallas/Fort Worth International Airport opened in 1973 and has since become the 4th busiest airport worldwide, welcoming over 75 million passengers in 2019. 

Flying out of the DFW airport is a mini-vacation in itself. You can visit the spa, practice yoga in the dedicated yoga area, and even take a nap in their newly introduced pay-by-the-hour sleep pods.

4. Washington Dulles International Airport (IAD): 20.3 sq. mi. | 52.6 sq. km.

When the PKX airport opened in 2019, it became Beijing’s second international airport and is expected to be one of the world’s busiest airports in the near future, with flights traveling to 120 destinations. 

The starfish design of the terminal was built to allow passengers to walk from check-in to their allocated gate in 8 minutes or less – talk about convenience.

Water management systems, solar panels, and waste heat recovery systems were all put in place to limit the airport’s impact on the environment.
