It is exciting to analyze the latest traffic figures and put together the world’s biggest airport ranking every month. As always, we clustered the ranking in three sections: biggest airports by flight volume, biggest airports by passengers, and biggest airports by cargo volume.
World’s Biggest Airports By Flight Volume — in June 2021
Based on flight volume, the biggest airport ranking for June is —almost— a U.S.-only show. 14 of the 15 biggest airports by flight volume are based in the United States of America. Moreover, with Chicago and Atlanta, the United States has the only airports that operate more than 30,000 flights in June. On top of that, Dallas scratched the 30,000 mark and is only 400 flights shy of 30,000.
Compared to 2019, almost every airport handled fewer flights in June 2021. However, anchorage, Salt Lake City, and Long Beach are the exception: Each of the three airports operated more flights than pre-COVID.

World’s Biggest Airports By Number of Passengers — in June 2021
When looking at the passenger figures, the picture looks similar to the traffic ranking. However, this time four Chinese airports challenge the U.S. dominance. On another page, it is interesting to see that, although Chicago operated the most flights, it “only” ranks fourth according to passenger numbers. Atlanta, on the other side, operates almost 600,000 flights more than Dallas on position two.
Chengdu, Shanghai, Beijing, and Xi’an represent the Chinese airports among the list of the 15 biggest airports by passengers in June 2021.
