For the 18th year in a row, Hartsfield-Jackson Atlanta International Airport was named the world's busiest airport in Airports Council International's annual report.
In 2015, more than 101 million passengers flew through Atlanta, an increase of 5.5% over the previous year. The report cited the location of Georgia's capital as a major contributing factor—80% of people in the U.S. live within a two-hour flight of the city.
Beijing's airport came in second, with 89.9 million passengers, and Dubai jumped into third place from sixth in 2014.
Chicago's O'Hare occupied the fourth slot, making it the second busiest airport in the U.S.
The figures were good news for airports overall, reflecting a 6.4% increase in worldwide passenger traffic.
