Airports are of extreme importance in our increasingly interconnected world. That’s why some of them can get busy, very busy. So let’s take a tour of the biggest airports in the world, continent by continent in 2025.
What is the biggest airport in the world by size?
King Fahd International Airport, Dammam, Saudi Arabia
- Technically, the area that King Fahd International Airport takes up is 776 sq. km, making it the largest airport in the world (and bigger than Bahrain).
- Finished in 1990, it was used by the US Airforce during Operation Desert Storm and only opened for commercial use in 1999.
- Of the two runways, one is used by the national oil company Saudi Aramco, while the other is open to regular commercial traffic.
Fun fact: It’s larger than the entire country of Bahrain, but only around 5% is actively used for aviation purposes.

What is the biggest airport in Asia?
Beijing Capital International Airport, Beijing, China
- BCIA was opened in 1958. Currently, some of its traffic is being handed over to Beijing Daxing International Airport.
- It’s not only the biggest airport in Asia, but also the second busiest airport in the whole world.
- Its IATA code, PEK, is a hold-over from the time when Beijing was romanized as Peking.
- Size: it covers an area of 780,000 sq. m. with 104 boarding bridges.

What is the biggest airport in Africa?
O. R. Tambo International Airport, Johannesburg, South Africa
- O. R. Tambo is the busiest airport in Africa, handling over 21 million passengers annually.
- It was originally named Jan Smuts International Airport, had a name change to Johannesburg International Airport, and eventually ended up being O. R. Tambo.
- O.R. Tambo hosts the 33rd longest runway, a necessary measure for loaded planes to take off at this altitude.
- Total size: 1673 ha (6.46 sq. m.)
Fun fact: O. R. Tambo’s high altitude (1,700+ metres above sea level) requires extra-long runways, one of the longest in Africa at 4.4 km.

What is the biggest airport in Antarctica?
McMurdo Station’s airport complex
- It is the largest U.S. research base on the continent and a critical logistical hub for Antarctic operations.
- Unlike typical airports, McMurdo doesn’t have a single large terminal building. Instead, it relies on multiple runways built on compacted snow and sea ice.
- The McMurdo Ice Runway, the most commonly used, stretches over 3 km to accommodate heavy aircraft.
Fun fact: These runways are rebuilt from scratch each year, as weather conditions make permanent infrastructure impossible.
What is the biggest airport in Europe?
Charles de Gaulle Airport (CDG), Paris, France
- It’s the largest airport in France and the second busiest in Europe.
- In a typical year, it handles over 76 million passengers, with nearly 500,000 flights.
- New Terminal 4 project on hold: The massive Terminal 4 expansion was officially cancelled in 2021 due to environmental concerns. It’s a clear sign that even major airports like CDG are rethinking growth for sustainability.
- Charles de Gaulle is also a significant cargo hub, serving as the European hub for FedEx and La Poste.
- Size: 32.38 sq.km.
Fun fact: Charles de Gaulle Airport boasts its own high-speed TGV train station right under Terminal 2, connecting the airport directly to cities like Lyon, Marseille, and even Disneyland Paris.
What is the biggest airport in North America?
Denver International Airport, Denver, Coloardo, United States

- Fun fact: The airport’s signature blue horse sculpture, “Blucifer,” is infamous for its glowing red eyes and urban legends.
What is the largest airport in South America?
São Paulo–Guarulhos International Airport, São Paulo, Brazil
