Piedmont Airlines (PDT) — 36 Aircraft Fleet/ PT

Piedmont Airlines was a regional carrier headquartered in Winston-Salem, North Carolina, that operated from the 1950s until its merger with USAir (now US Airways) in 1987. The airline primarily served the eastern United States with a hub in Charlotte, North Carolina, focusing on regional passenger operations that fed traffic to major carriers. Piedmont was known for its strong presence along the U.S. East Coast and maintained a reputation for reliable service on regional routes. The airline operated a fleet of regional aircraft and offered standard economy cabin service typical of regional carriers of that era. Following its acquisition by USAir, Piedmont's operations were integrated into USAir's network, and the brand was eventually phased out, though Piedmont Airlines was later revived as a subsidiary of US Airways before being merged into the mainline carrier.
