Piedmont Triad International Airport — Greensboro, United States

Named for the Piedmont Triad, a tri-city metropolitan cluster encompassing Greensboro, Winston-Salem, and High Point, GSO reflects a regional governance model in which multiple North Carolina cities jointly support a single shared commercial airport. The Triad region built its early economic identity around tobacco, textiles, and furniture manufacturing, industries that have since given way to logistics, aviation manufacturing, and healthcare as key employers. Honda Aircraft Company maintains significant operations at the airport, producing business jets, while cargo carrier FedEx operates a major regional sorting hub from the field, giving GSO an outsized role in overnight package logistics for the broader Southeast. Passenger service connects the Triad to major domestic hubs, supporting business travel for the area's diversified manufacturing and corporate base without the congestion found at larger nearby airports.
