Cape Girardeau Regional Airport — Cape Girardeau, United States

Overlooking the Mississippi River in Missouri's southeastern Bootheel region, Cape Girardeau Regional Airport keeps a small city with deep river-trade roots connected to the national air network through subsidized commuter flights, a lifeline typical of many similarly sized American communities. The surrounding city, home to Southeast Missouri State University and a historic downtown floodwall mural depicting the region's river heritage, relies on the airport for business travel that would otherwise mean a long drive to St. Louis or Memphis. Twin runways handle a mix of scheduled turboprop service, general aviation, and occasional cargo flights. Barge traffic on the river below remains as important to the local economy as anything moving through the terminal.
