Quincy Regional Airport Baldwin Field
Quincy Regional Airport (IATA: UIN, ICAO: KUIN, FAA LID: UIN; Baldwin Field) is a city-owned airport 12 miles east of Quincy, a city in Adams County, Illinois, United States. It is used for general aviation but also sees Contour Airlines flights to Chicago's O'Hare International Airport and Nashville, a service which is subsidized by the federal government's Essential Air Service program at a cost of $1,956,856 (per year). The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023–2027 categorized it as a national non-primary commercial service facility. The first airline flights were on Mid-Continent in 1947; successor Braniff left in 1959. TWA arrived in 1948 and left in 1953-54; Ozark arrived in 1950 and left in 1982. It is the least busy of the 12 commercial airports in Illinois. Quincy has a solar panel project that was finished in early 2023. The airport has often played host to events held by the International Stinson Club, including fly-ins, job fairs, and more.
