In 1983, Piedmont Aviation bought Henson and re-branded the airline as "Henson, The Piedmont Regional Airline." Under Piedmont's control, the airline expanded rapidly, particularly in Florida. Both were purchased by the USAir Group in 1987 with Piedmont absorbed two years later and Henson's aircraft repainted in USAir Express livery. The 1980s saw rapid growth by the company, first resulting the upgrade of its fleet to the De Havilland Canada Dash 8 aircraft, and an expansion in the fleet size. With the growth in passenger capacity, the airline made a geographic expansion to Florida, including numerous intrastate routes in Florida, and it opened a maintenance facility in Jacksonville.
The Piedmont name was resurrected in 1993, when USAir (now US Airways) renamed Henson to "Piedmont Airlines". This was done to protect the Piedmont brand name, which could be used by others if not exercised in trade use for a period of time. USAir continued this practice by changing the name of its two other wholly owned regional airline subsidiaries, Jetstream and Allegheny Commuter, to PSA Airlines and Allegheny Airlines, respectively. (Pacific Southwest Airlines was the name of a California-based airline merged into USAir.) In 1997, USAir was renamed US Airways, and Piedmont was likewise re-branded as a US Airways Express carrier. US Airways merged Allegheny Airlines into Piedmont in 2004. The airline has 6,150 employees (at November 2007).
As of January 2008 the Piedmont Airlines fleet includes :
