Aberdeen Regional Airport was founded as Aberdeen Municipal Airport in 1921, north of Aberdeen, SD. It included two 2,500 foot runways as well as ground services. Additionally, Security Skycraft Corporation began regularly scheduled service from Aberdeen Municipal Airport at a cost of 50¢ per mile. In 1923, Aberdeen hosted the first fly-in event in South Dakota. In 1930, funds were allocated for the purchase of 160 acres of land for the airport, in a different location. Gravel runways and a steel hangar were also added. In 1946, the airport's name was changed to Saunders Field in honor of Brigadier General Laverne Saunders, and the name was changed again to its current name, Aberdeen Municipal Airport, in 1979. The airfield area is still called Saunders Field. The, airfield was converted into a commercial airport with North Central Airlines operating DC-9-30, DC-3, and Convair CV5800 aircraft to Minneapolis. A new terminal was built too which featured a restaurant dubbed, "Airport Cafe". Starting in 2015, Sun Country Airlines began seasonal charter air service to Laughlin/Bullhead using Boeing 737-800 aircraft dubbed casino flights. In 2019, a new larger jetway was added to the airport, which was able to support aircraft as big as an Airbus A321. The long 15 year CRJ200 service at the airport ended in October 2023 being replaced by the CRJ700, and CRJ900, followed by the CRJ550 a year later.
