It is located at the crossroads of Snickersville Pike (Virginia Secondary Route 734) and Airmont Road (Virginia Secondary Route 719) approximately 4 miles (6.4 km) south of the town of Round Hill and 3 miles (4.8 km) east of the village of Bluemont.

Though the crossroads location of Airmont had hosted a collection of dwellings and a general store since not long after the opening of the Snickersville Turnpike, it was not considered a village nor called Airmont until 1897 when the United States Post Office established a branch there.

The post office at Airmont did not last long, falling victim to Rural Free Delivery in 1912.

In its short life the post office greatly helped the small village grow, reaching a population of 25 by 1908, prompting the establishment of a school the following year.

Like most small villages in western Loudoun, Airmont began a slow decline during the Great Depression.
