The world's busiest airports by passenger traffic are measured by total passengers (data from Airports Council International (ACI)), defined as passengers enplaned plus passengers deplaned plus direct-transit passengers. Hartsfield-Jackson International Airport in Atlanta has been the world's busiest airport every year since 2000; with all airports combined London has the world's busiest city airport system by passenger count.

For consistency, the ACI's annual figures are always used in the final presentation and ranking, even where figures given by airport operators or authorities differ.

Hartsfield-Jackson, is located seven miles (11 km) south of the central business district of Atlanta, Georgia, United States. It has been the world's busiest airport by passenger traffic since 1998, and by number of landings and take-offs since 2005. Hartsfield-Jackson held its ranking as the world's busiest airport in 2012, both in passengers and number of flights, by accommodating 95 million passengers (more than 260,000 passengers daily) and 950,119 flights.
