The airport opened in November 1946[1] and was named for George Armstrong Custer, who spent much of his early life in Monroe.

[2] Custer Airport is owned by the city of Monroe and is financially supported through hangar rentals, landing fees, and fuel sales.

It is located on North Custer Road (formerly designated as M-130) about two miles (3.2 km) northwest of Monroe's downtown area.

The airport property itself—occupying 158 acres (64 hectares)—is an exclave of the city limits and is separated by a one-quarter mile (0.4 km) wide undeveloped residential area belonging to Frenchtown Charter Township.

The airport's fixed-base operator offers general maintenance, aircraft parking, courtesy transportation, rental cars, a crew lounge, and more.

Custer Airport is located approximately 9.5 miles (15.3 km) from the Enrico Fermi Nuclear Generating Station in neighboring Frenchtown Charter Township.
