Airport traffic for over 2,600 airports in more than 180 countries and territories is analyzed to find the world’s busiest airports.
Airports Council International (ACI) World has revealed the world’s busiest airports using the World Airport Traffic Dataset – the industry’s most comprehensive airport statistics dataset.
In 2021, the world’s airports accommodated 4.6 billion passengers, representing an increase of 28.3% from 2020 or a drop of 49.5% from 2019 results. The top 20 airports, representing 19% of global traffic (863 million passengers), experienced a gain of 42.9% from 2020 or a drop of 31.9% vis-à-vis their 2019 results (1.27 billion passengers in 2019).
Hartsfield-Jackson Atlanta International Airport (ATL, 75.7 million passengers, +76.4%) is back on the top of the 2021 rankings followed by Dallas Forth Worth (DFW, 62.5 million passengers, +58.7%) and Denver (DEN, 58.8 million passengers, +74.4%).
From the top 20 rankings, almost all airports have significant domestic traffic representing 65% to 100% of their total passengers. The only exception is Istanbul International Airport (IST) with a larger international traffic share (72% of passenger traffic).

Air cargo volumes increased by 15.4% year-over-year (+4.5% versus 2019), to a record 125 million metric tonnes in 2021. Air cargo volumes in the top 20 airports, representing around 44% (54.8 million metric tonnes) of the global volumes in 2021, gained 14.7% in 2021 year-over-year or 13.4% versus 2019. The gain can be attributed to improved economic conditions that drove an increase in demand for consumer goods and pharmaceutical products (such as personal protective equipment and vaccines).
Hong Kong (HKG, 5.0 million metric tonnes, +12.5%) regained top rank from Memphis (MEM, 4.5 million metric tonnes, -2.9%) who inched back to second position, followed by Shanghai (PVG, 4 million metric tonnes, +8.0%) in third. Compared to pre-pandemic levels, the biggest jump in the top 20 rankings was recorded for Chicago’s O’Hare International Airport (ORD), which improved its position by seven spots, from 18th in 2019 to 11th in 2021.

2021 global aircraft movements are close to 74 million, representing a gain of 18.7% from 2020 results or -28.2% versus 2019.

ATL is at the top with 708 thousand movements (+29.1% from 2020) but still below its 2019 result of 904 thousand movements (-21.7%). ORD is still in second rank after leading ATL in 2019 and 2018.
