Largest airports in the world

With the exponentially growing demand for air travel, top airports globally have most recently been overwhelmed with the influx of passenger traffic. The need to accommodate more individuals has proven dire and led to expanding or constructing larger ones.

Thankfully, the course of extension or erection of bigger airports has now significantly become a new competition. In September 2019, late Zaha Hadid’s “starfish” airport masterpiece quickly made the list after its grand opening. Among the myriad of potential airports vying to dethrone King Fahd International Airport could be Dallas/Fort Airport after a few successful upgrades. Denver International Airport in Denmark significantly trails King Fahd International Airport, with a wide gap between it and Dallas/Fort Worth International Airport in the land area covered.

This increase in size evolution can’t be more beneficial to prospective passengers and their owners themselves. But it’d be fun to rank the ten largest airports in the world by land area.

10. Suvarnabhumi Airport (BKK) – (32.4 sq. km)

what are the largest airports in the world


Also unofficially known as Bangkok Airport, the international airport is one of two in Bangkok, Thailand. It is one of the biggest in Southeast Asia and unarguably the largest in the country, covering 32.4 sq km (8000 acres).

Since its initial launch in 2004, Bangkok Airport has been the hub for Bangkok Airways, K-Mile Air, Thaiviejet Air, Thai Smile, and Thai Airways. It fully commenced international flights in September 2006. Lufthansa Cargo from Mumbai, India, was the first flight to grace the runway from abroad, while a Saudi Arabian airline was the first cargo departure.

The world-class airport has as many as 130 passport control checkpoints for arrivals and 72 for departures. The 26 customs control checkpoints are made available for arriving passengers, while eight checkpoints are functional for departing ones. Despite the 83 escalators, 102 elevators, and 107 moving walkways open, bumping up against fellow passengers or staff is still very common.

Bangkok Airport has two parallel runways. Each of 60m width and 4000 & 3700 meters long, respectively.

The airport’s overall stunning design, credit to Murphy/Jahn Architects, is a significant reason it was the most popular global venue to take Instagram photos in 2012.

9. Cairo International Airport (CAI) – 36.25 sq. km.


Covering 36.25 sq km, there isn’t any larger airport than Cairo International Airport in Africa. The Egyptian airline is also the busiest in the country, as it handled over 17 million passengers in 2018.

Cairo airport is the primary hub for EgyptAir and Nile Air.

Cairo International Airport was initially built with four terminals for both private and non-commercial aircraft services. But during an upgrade, the third (and largest) terminal, International Hall 3, was demolished due to reconstructing a new hall for international arrivals.

The numerous facilities occupying the 14 sq mi area include the AirMall, the luxurious five-star Le Meridien Hotel, a multi-story, and a multi-story car park.

In 2010, Cairo International Airport was one of the three most improved airports by the Skytrax World Airport Awards. It then laudably became the second Best Airport in Africa of the Airport Service Quality Awards by Airports Council International a year later.

what are the largest airports in the world

Pudong airport is the central hub for Asian airlines, including Air China, Shanghai Airlines, China Eastern Airlines, Spring Airlines, and Juneyao Airlines. Asian-Pacific cargo airlines include FedEx, UPS, and DHL, the largest express hub in Asia.

Despite not being the biggest, Shanghai Pudong airport is disputedly the busiest international hub in China. By cargo traffic, it was the world’s third most active in 2017, handling 3,703,431 tons. Pudong airport hosted at least 104 airlines in 2016, with more than 210 destinations served. By passenger traffic at the end of 2018, the airport was the fifth-busiest in Asia and eighth busiest in the world.

To increase annual passenger capacity in 2021, the government opened a third passenger terminal with a satellite terminal and two more runways. It initially had four operational runways on both sides of two passenger terminals, but it proved insufficient for the fast-growing hub.

Pudong airport’s continual upgrades may see it surpass others in the ranking soon, but presently, it remains the eighth largest by land area.

7. George Bush Intercontinental Airport (IAH) – 44.51 sq. km

what are the largest airports in the world

2. Denver International Airport (DEN) – 135.71 sq. km

what are the largest airports in the world


Ranking 2nd on our list of largest airports in the world is Denver international airport. As broad as 135.7 sq km, it is also the largest airport in North America. It is located far from residential areas in Northeast Denver, Colorado, to avoid aircraft noise and accommodate an ample space.

Denver airport is among the primary hubs for United Airlines and Frontier Airlines. It currently offers service to 215 worldwide destinations amongst 23 different airlines. With 35,000 employees, it has the highest in Colorado and significantly one of the largest compared to other airports.

Ranking on our list of the largest airports in the world is the King Fahd International Airport, DMM, the largest of them, covering an unbelievable 776 sq km area.

DMM is located in Dammam, Saudi Arabia, and is the hub for SaudiGulf Airlines, Flynas, Saudia, and Aramco Aviation. It has two runways of 4,000 miles and a terminal area of 3.52 million square feet.

The airport also has a plant nursery that supplies its gardens with trees and plants. It covers 2.3 million square feet and contains three greenhouses and a long stretch of green fields.

DMM isn’t as busy as most of the others, it currently tops in the list, but its enormous size makes it more than deserving of a spot in any ranking.


Although larger airports can mean fewer queues and more time saved for passengers, they can also mean the opposite for busier ones. If the annual passenger growth rates keep surging, there are low chances of travelers relishing its size advantage. But regardless of the potential downsides among all its ups, it’ll always be a welcome development for all.
