Piedmont also provides ground handling and customer service for airports in the northeastern and western United States.

Piedmont operates a fleet consisting exclusively of Embraer ERJ 145 regional jet aircraft.

It began its first scheduled flights to Washington National Airport in 1962 under the Hagerstown Commuter name, later changed to Henson Airlines.

It initially developed a route structure serving Washington D.C., Philadelphia and Baltimore, while establishing a new headquarters for Allegheny Commuter at Salisbury, Maryland in 1968.

The airline operates maintenance bases in Albany, Charlotte, Harrisburg, Philadelphia, Richmond, Roanoke and Salisbury.
