Commercial aviation and military aviation have been intertwined in Montgomery. The first commercial air services in Montgomery operated at Maxwell Field, a military facility founded by the Wright Brothers west of the city. To provide for commercial aviation the City of Montgomery opened its original municipal airport in 1929 east of the city. This facility was later named Gunter Field and was served by a predecessor of American Airlines. Eastern Air Lines subsequently took over service at Gunter.

In 1940 the War Department chose Gunter Field for a new pilot training facility. Gunter quickly became congested, Eastern Airlines was forced to move temporarily to Maxwell, and the city purchased a tract southwest of downtown on US 80 to replace Gunter for civilian aviation. Separately, the Army Air Forces identified a need for seven auxiliary fields in the vicinity of Gunter and the city and USAAF agreed that the city's newly purchased site would also serve as Gunter's auxiliary field #6. It opened in 1943 and was named for ENS Clarence Moore Dannelly Jr., USN, a Navy pilot killed in a 1940 training accident and considered to be the first casualty of World War II from Montgomery. The old Army Air Forces hangars are now part of the Montgomery Aviation complex. The original three runways and their original dimensions were:

3/21: 4,000 by 150 feet (1,219 m × 46 m). Still exists.

9/27: 3,500 by 150 feet (1,067 m × 46 m). Extended to 7,000 ft (2,100 m) in 1955. Extended to 9,000 ft (2,700 m) in 1963. Redesignated 10/28 in 1992.

15/33: 4,000 by 150 feet (1,219 m × 46 m). Closed in 1981. Some portions remain as taxiway and apron.

When Dannelly Field opened, Eastern moved its operations there. The city took title to Dannelly in 1946, although joint commercial and military use continued, and erected a permanent passenger terminal and control tower north of Runway 9/27 in 1955. While Runway 9/27 was being rebuilt in 1963, and again in 1970, commercial flights were temporarily diverted to Maxwell AFB.
