Hartsfield-Jackson International Airport again wears the double crown as the world's busiest airport, ranking highest in both flight counts and passengers for 2015.

The Atlanta airport lost half of its title when its flights counts for 2014 fell below that of Chicago O'Hare International Airport's traffic.

But the 2015 figures are out, and Atlanta has retaken the No. 1 spot from Chicago for flight totals. Hartsfield-Jackson had a total of 882,497 flights compared with O'Hare's 875,136, according to Federal Aviation Administration Statistics.

Hartsfield-Jackson International Airport has lost one of its two titles for world's busiest airport, with Chicago O'Hare taking the title for the most flights, according to year-end data from Flight Aware. Atlanta still carries millions more passengers, but for many years it held both titles. The decline in takeoffs and landings in Atlanta came as Delta Airlines retires regional jets and replaces them with larger planes, while Southwest Airlines cut back on AirTran flights here.
