Largest Airport by Number of Annual Passengers (2000–2024)
Air travel has become one of the defining features of globalization, connecting continents, economies, and cultures. At the heart of this vast network are the world’s busiest airports—aviation giants that handle tens of millions of passengers every year. From 2000 to 2024, the title of largest airport by annual passenger traffic has changed hands multiple times, reflecting shifting travel patterns, economic growth, airline hubs, and global crises.
This article explores which airport was the busiest each year, why dominance shifted, and how global events reshaped aviation over the last two decades.
What Does “Largest Airport” Mean?
In aviation statistics, the largest airport typically refers to the airport with the highest number of annual passengers, including:
-
Departing passengers
-
Arriving passengers
-
Transit passengers
This metric measures human traffic, not aircraft movements or cargo volume.
The Early 2000s: The Rise of Atlanta (2000–2007)
🥇 Hartsfield–Jackson Atlanta International Airport (ATL)
From the year 2000 onward, Atlanta (ATL) emerged as the world’s busiest airport—and would go on to dominate the ranking for most of the next 25 years.
Why Atlanta?
-
Strategic location in the southeastern United States
-
Hub of Delta Air Lines
-
Efficient domestic connectivity
-
Short average flight times to most major U.S. cities
During the early 2000s, ATL handled roughly 75–85 million passengers annually, a staggering figure at the time.
Mid-2000s Expansion: Global Aviation Boom (2004–2007)
The mid-2000s marked a golden era for air travel:
-
Rising middle classes
-
Cheap fuel
-
Expansion of low-cost carriers
-
Increased international tourism
Other major contenders included:
-
Chicago O’Hare (ORD)
-
London Heathrow (LHR)
-
Tokyo Haneda (HND)
However, Atlanta remained unbeaten, largely due to the scale of U.S. domestic travel.

📉 Global Financial Crisis Impact
The 2008 global financial crisis caused a sharp decline in air travel:
