Airports Council International (ACI) World has released its 2025 report of airport traffic, international passenger, air cargo and aircraft movement rankings. Hartsfield-Jackson Atlanta International Airport (ATL), which welcomes 106.3 million passengers in 2025, held on to its place as the world’s busiest airport for passenger traffic while Dallas Fort Worth International Airport (DFW), Chicago O’Hare International Airport (ORD) and Denver International Airport (DEN) ranked as fourth, sixth and tenth busiest respectively. ORD topped the charts in aircraft movements, with ATL, DFW, DEN, Harry Reid Las Vegas International AIrport (LAS), Los Angeles International Airport (LAX) and Charlotte International Airport (CLT) rounding out the top ten. Miami International Airport (MIA) and Memphis International Airport (MEM) were ranked 5th and sixth busiest airports for air cargo activity in 2025. U.S.-based airports did not crack 2025’s top ten list of airports with the most international passenger traffic. The report notes that global airport traffic rose 3.6% in 2025.
“We congratulate the world’s busiest airports for managing growing air travel demand amid increasing operational complexity,” said ACI World director general Justin Erbacci. “These hubs keep people and goods moving, supporting global trade, tourism, and economic growth in their communities and regions. To help keep pace with rising demand, governments must prioritize sustained investment in airports and the broader aviation ecosystem.”
