It is owned and operated by the Jacksonville Aviation Authority.
The airport covers 7,911 acres (3,201 ha) and has two concrete runways: 08/26, 10,000 x 150 ft (3,048 x 46 m) and 14/32, 7,701 x 150 ft (2,347 x 46 m).
The terminal at JIA is composed of a baggage claim area, on the first floor and a ticketing area on the second floor, at the front of the structure.
Past baggage claim and ticketing is the mezzanine, where shops, restaurants and the security checkpoint are located.
Beyond the mezzanine are the airport’s Concourses A and C, which include 10 gates each (for a total of 20), along with other shops and restaurants.
Construction started in 1965 on a new airport to handle travel to nearby naval bases.
The new airport was dedicated on September 1, 1968, replacing Imeson Field.
Terrain precluded lengthening the runways at Imeson, a necessity with the inception of commercial jet airliners.
A new idea at JIA was separating departing and arriving passengers on different sides of the terminal (as can be seen in the photo on this page).
This is no longer the case, and the airport (which has greatly expanded since the picture was taken) now uses the more typical layout with departing passengers on an upper level with an elevated roadway, and arriving passengers on the lower level.
