• Hartsfield-Jackson Atlanta International Airport is once again the busiest airport in the world.
• Nearly 104 million passengers traveled through ATL in 2017.
• Airports Council International compiled its list of the busiest airports in the world using data from 1,202 airports around the world.

Airports Council International (ACI) released its latest list of the busiest airports in the world. Once again, Hartsfield-Jackson Atlanta International Airport took the top spot with nearly 104 million passengers in 2017. Even though total traffic figures at ATL fell by 0.3%, it was enough to hold off Beijing Capital to retain the crown.

According to ACI, global passenger figures increased 6.6% in 2017 while total aircraft movements went up by 2.4%.

"The surge in cargo volumes and passenger numbers across many of the world's airports is a testament to heightened business and consumer confidence, at least in the short term," ACI World director general Angela Gittens said in a statement. "The world's airports continue to be a vital link in the economic multiplier effect that aviation provides and the role it plays as an enabler for global commerce is growing."

The trade group compiled its list using data from 1,202 airports from around the world.

The top 20 airports accounted 17% of the 1.5 billion passengers who passed through airports around the world in 2017.
