Hartsfield-Jackson Atlanta International Airport is Atlanta's primary commercial airport and a major global airline hub, built around parallel runways and a midfield terminal-and-concourse complex. The airport operator lists five runways: 9R/27L, 9L/27R, 8R/26L, 8L/26R and 10/28. The longest, 9L/27R, is listed as 12,390 ft (3,776 m); the runway-length field uses that operator-published metre value.
