Every single day, millions of people rush through airport halls with their bags, heading to places all over the world. Some airports handle so many travelers that they’re like small cities that never sleep. Let’s take a look at the busiest airports on Earth and what makes them so incredibly busy.
The Champion: Atlanta’s Hartsfield-Jackson Airport
For over 25 years, Atlanta’s Hartsfield-Jackson International Airport has held the crown as the world’s busiest airport. In 2024 alone, it welcomed 108.1 million travelers through its doors. To put that in perspective, imagine if every single person living in the Philippines decided to fly through one airport in the same year – that’s how many people Atlanta handles!
What makes Atlanta so busy? It sits right in the heart of the southeastern United States, making it a perfect stopping point for flights going anywhere. Delta Air Lines calls Atlanta home, which means lots of connecting flights happen here. If you’re flying from New York to Los Angeles or from Miami to Chicago, there’s a good chance you’ll change planes in Atlanta.
The airport is huge too. It has seven runways and can handle over 2,500 flights every day. It would take 30 minutes Walking from one end to the other
The Runner-Up: Dubai’s Gateway to the World
Dubai International Airport comes in second place on the busy list. In August 2025, it had space for 5.35 million passengers. That’s 3% more people than the same time last year, showing the airport keeps getting busier. Dubai sits between Europe, Asia, and Africa, making it the perfect place to stop when traveling between continents.
Emirates Airlines has made Dubai their main hub, and they fly giant double-decker planes called Airbus A380s. These massive planes can carry over 500 people each. Dubai’s airport feels more like a fancy shopping mall than a regular airport, with gold shops, spas, and even an indoor waterfall.

The Big Surprise: Shanghai’s Amazing Jump
Shanghai Pudong International Airport saw the biggest jump in rankings, going from number 21 in 2023 up to number 10, with a whopping 41% increase in traffic.This big increase happened because China made it simpler for travelers to come by changing their travel rules and adding more flights.
Shanghai’s growth shows how quickly things can change in the airport world. Just a few years ago, many Chinese airports were much quieter because of travel restrictions. Now they’re booming again.
What Makes an Airport Super Busy?
Several things make airports handle millions of passengers:
Location, Location, Location: The busiest airports sit in perfect spots for connecting flights. They’re like the world’s biggest train stations, but for planes.
Hub Airlines: Big airlines choose certain airports as their main bases. This brings a huge amount of flights and passengers to one place
Big Cities: Airports in huge cities naturally get more travelers. More people living nearby means more people flying.
International Connections: Airports that connect different continents stay busy with travelers making long journeys.
Behind the Numbers: How They Count
Just the top 20 busiest airports handled 1.54 billion travelers combined, which represents about one out of every six flights taken worldwide.These numbers come from counting every person who gets on a plane at each airport. If you change planes somewhere, you get counted at both airports.
The Airports Council International tracks these numbers by collecting data from over 2,800 airports worldwide. It’s like taking the world’s biggest attendance count every single day.
The Biggest vs. The Busiest
When people ask about the “biggest and busiest airport in the world,” they might mean different things. Atlanta wins for most passengers, but other airports win in different ways:
- Biggest by size: King Fahd International Airport in Saudi Arabia covers the most land
- Most runways: Chicago O’Hare and Dallas Fort Worth both have lots of runways
- Most flights per day: Atlanta again, with over 2,500 daily flights
Why These Numbers Matter
Busy airports mean busy economies. When millions of people travel through an airport, they create jobs for pilots, flight attendants, baggage handlers, security guards, restaurant workers, and thousands of others.
These airports also connect our world. They make it possible for someone in small-town America to visit their family in Asia, or for business deals to happen between companies on different continents.
The Recovery Story
Even Hartsfield-Jackson Atlanta International Airport hasn’t fully returned to 2019 levels yet, showing that airports are still bouncing back from the travel shutdowns during the pandemic. But passenger counts keep going up each year as more travelers feel safe about flying again.
The busiest airports in the world are more than just places where planes take off and land. They’re the beating hearts of global travel, connecting families, enabling business, and making our big world feel a little bit smaller. Next time you’re rushing through a busy airport, remember that you’re part of an amazing system that moves millions of people around our planet every single day.
