What will be the largest airport in the world in 2025?
Partager
Did you know that some airports are so vast they could almost swallow an entire city? Whether by land area or the number of passengers welcomed each year, the world's largest airports defy imagination. But which one truly holds the title of "world's largest airport"? The answer depends on the criterion used: area, passenger traffic, number of runways... In this article, we take stock of the giants of the sky that dominate global air traffic.
What do we mean by "world's largest airport"?
When we talk about the largest airport, we first need to clarify what we're talking about. Is it physical size? The number of passengers? The volume of freight transported? Each of these criteria yields a different ranking.
Area vs. traffic: two different podiums
An airport can be immense in terms of area without necessarily welcoming the largest number of passengers. This is the case for some hubs in the Middle East or Asia that have been designed for massive future development. On the other hand, some more "compact" airports manage colossal traffic thanks to excellent organization.
Other criteria to consider
Airports could also be ranked by the number of runways, cargo capacity, or the extent of services offered. But to keep things clear, let's focus on the two most significant rankings: by area and by number of passengers.
The world's largest airport by area
King Fahd International Airport (Saudi Arabia)
Located in Dammam, Saudi Arabia, King Fahd International Airport is, to date, the largest in the world by area. It spans over 780 km², a size equivalent to that of Paris... multiplied by seven!
Built in the 1990s, it was designed to meet the long-term needs of regional development. It is not, however, the busiest, but its astronomical size makes it a true city within a city, with internal roads, residential areas, and even a mosque that can accommodate thousands of worshippers.
The world's largest airport by passenger traffic
Hartsfield-Jackson Atlanta International Airport (United States)
In terms of passengers, Atlanta Airport (ATL) retains its title as the world leader. In 2024, it welcomed over 104 million passengers, an impressive figure that reflects its role as an essential hub in the United States.
Its strength? An ideal location in the heart of the American Southeast, a major transfer platform for Delta Airlines, and a highly streamlined organization. Despite a limited number of runways compared to other airports, its optimized management allows it to handle takeoffs and landings at an impressive rate.
Other giant airports around the world
Even if they don't hold the official title, several airports deserve special mention:
Beijing-Daxing (China)
Opened in 2019, it impresses with its futuristic architecture and gigantic capacity. Designed to eventually accommodate over 100 million passengers, it is already a major player in Asia.
Dubai (DXB)
The world's leading airport for international traffic, Dubai plays a role as a gateway between the West and Asia. In 2024, it welcomed nearly 90 million passengers.
Heathrow (London)
The main hub in the United Kingdom, Heathrow remains a key player in Europe despite expansion limitations related to its location.
Why are these airports so big?
Hubs at the heart of global traffic
These airports are not just large buildings: they are ultra-connected logistical platforms, linking continents together. Their size reflects their importance in the global network.
Tourism, business, and geopolitics
A large airport often reflects an economic or geopolitical ambition. Dubai, for example, has made its airport a strategic tool to attract businesses and tourists from all over the world.
A vision for the future
Beijing-Daxing or King Fahd were not built to meet only current needs, but to anticipate the coming decades, with infrastructure designed for continuous growth.
