World’s Busiest Airports in April 2021

For many airports, traffic figures continue to grow. We wanted to know the details again and took a look at the official ICAO traffic figures. Therefore, we analyzed the world’s busiest airports regarding the number of passengers, flights (departures), and freight volume. And here’s the result: The world’s busiest airports — based on April 2021 traffic figures. Here’s what’s contained in detail:

World’s Top 15 Busiest Airports by Passenger Numbers

Key Takeaways

Guangzhou remains the world’s busiest airport for passengers.
In April 2021, China’s Guangzhou (CAN) airport (again) wins the label “world’s busiest airport” by passenger numbers. Compared to March, Guangzhou recorded another growth of almost 10%. However, Atlanta is close behind. Therefore, it will be interesting to see if Guangzhou will remain the world’s busiest airport or if Atlanta will push Guanzhou off the throne next month.

China and the United States continue to dominate the ranking
Again, the list of the world’s busiest airports is dominated by Chinese and U.S. airports. Seven out of 15 airports are based in China, whereas eight are based in the U.S. As a result, there’s no single airport among the busiest airport list outside of China or the U.S.

Beijing, Shanghai, and Charlotte are the top gainers
Looking at the growth rate compared to the previous month, it turns out that Charlotte (+17.1%) and Beijing (+17.5%) are the top gainers of the month. Besides that, Shanghai (+14.5%) performed very well too.
