Aviation enthusiasts often marvel at massive terminals and sprawling runways, but few realise how much territory the world’s largest airports consume. Picture this: the largest airport on our list could swallow Manhattan whole—and still have room for dessert!
As travellers rush through terminals racing to catch connections, they rarely consider they’re navigating through some of humanity’s largest built environments—entire cities dedicated to the art of flight.
Largest Airports in the World by Area
Here are the Top 10 Airports in the World by Area in 2025.
King Fahd International Airport, Dammam; Photo- KFIA1. King Fahd International Airport (DMM) — Dammam, Saudi Arabia — 776 km² (299.61 mi²)
King Fahd International Airport (DMM) dominates the aviation landscape as the undisputed titan of airport real estate. Spanning an astonishing 776 square kilometres, this Saudi Arabian giant occupies nearly as much land as New York City’s five boroughs combined.
Originally designed as a United States airbase during regional conflicts, the Saudi government transformed it into a commercial hub that officially opened in 1999.
Despite its massive footprint, King Fahd International (DMM) serves only about 10 million passengers annually, placing it outside the top 100 busiest airports globally.
The airport houses remarkable amenities, including a mosque capable of accommodating 2,000 worshippers simultaneously. Perhaps most intriguing is the airport’s self-contained residential community. It is complete with housing for 3,000 people, making it essentially a small city. Massive on-site greenhouses cultivate all landscaping plants used throughout the facility, creating a self-sustaining ecosystem within this aviation behemoth.

Denver International Airport (DEN) stands as North America’s largest airport and ranks second globally with an area of 135.7 square kilometres. Opened in 1995, DEN was designed with significant room for expansion—a foresight that has proven invaluable as passenger numbers continue to climb.
The airport’s iconic white tensile fabric roof mimics the snow-capped Rocky Mountains that serve as its backdrop. DEN handles over 69 million passengers annually, making it not just enormous but also operationally capable.
Denver International (DEN) gained notoriety for the numerous conspiracy theories surrounding its construction.
The airport has embraced this unusual reputation, occasionally playing into the rumours with tongue-in-cheek references in its marketing materials.
Dallas Fort Worth International Airport; Photo- DFW Airport3. Dallas/Fort Worth International Airport (DFW) — Dallas, Texas, United States — 69.6 km² (26.88 mi²)
Occupying nearly 70 square kilometres between the cities of Dallas and Fort Worth, Dallas/Fort Worth International Airport (DFW) ranks as the third-largest airport globally by land area. Since its 1974 inauguration, it has evolved into American Airlines‘ primary hub. It serves as a crucial gateway between the United States and Latin America.
DFW’s semicircular terminal design creates an efficient flow that minimises walking distances despite the airport’s considerable size. The facility has 5 terminals connected by an automated people mover system called Skylink. It travels at speeds up to 35 mph, making it one of the fastest airport transit systems worldwide.
The airport maintains its own zip code and postal service facility, essentially functioning as an independent municipality.
Environmental sustainability represents a core focus, with DFW becoming the first carbon-neutral airport in North America in 2020. The property includes significant natural areas, including protected wetlands that provide habitat for diverse wildlife species within this urban aviation centre.
Orlando International Airport Terminal C. Photo: HNTB4. Orlando International Airport (MCO) — Orlando, Florida, United States — 53.8 km² (20.78 mi²)
Orlando International Airport (MCO) spans nearly 54 square kilometres and serves as the primary gateway to central Florida’s tourism empire. Originally a military airfield called McCoy Air Force Base (which explains the MCO airport code), it transformed into a commercial airport in 1974 and now handles over 50 million annual passengers.
The airport’s design reflects Florida’s vacation atmosphere, featuring palm trees, water features, and abundant natural light throughout its terminals. Orlando International (MCO) pioneered the integrated hotel concept with its on-site Hyatt Regency, providing seamless accommodation for travellers.
As Disney World’s unofficial front door, MCO became one of the first airports to incorporate themed retail experiences. The airport maintains large conservation areas within its boundaries, with alligators occasionally spotted in waters near runways—a distinctly Floridian airport feature!
Washington Dulles International Airport; Photo- Wikipedia5. Washington Dulles International Airport (IAD) — Washington D.C., United States — 48.6 km² (18.75 mi²)
Washington Dulles International Airport (IAD) occupies nearly 49 square kilometers in Northern Virginia. It serves as a primary international gateway to the U.S. capital. Opened in 1962, Dulles features a distinctive main terminal with a sweeping, suspended roof that has become an architectural icon.
Dulles gained fame for its unique mobile lounges—bus-like vehicles that transport passengers between terminals and aircraft. Though largely replaced by an underground AeroTrain system, some mobile lounges remain in operation for remote gates, preserving this distinctive part of aviation history.
The airport serves as a living museum of aviation development, with operations ranging from the latest generation wide-body jets to historic aircraft displayed by the adjacent National Air and Space Museum Centre. This facility houses numerous aviation treasures, including the Space Shuttle Discovery and the Enola Gay B-29 bomber, creating an unparalleled aviation complex.
