Greater Portsmouth Regional Airport, also known as Scioto County Airport, is a public use airport located on State Route 335 in the community of Minford, Ohio, 10 nautical miles (12 mi, 19 km) northeast of the central business district of Portsmouth, a city in Scioto County, Ohio, United States. It is owned by the Scioto County Airport Authority. This airport is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility.HistoryThe airport opened on June 27, 1957 to replace another airport located in West Portsmouth which was situated near the Ohio River. When it first opened, Lake Central Airlines offered services to the airport until Allegheny Airlines merged with them in 1968. Allegheny continued service briefly before terminating service altogether. Since then, the airport has been without airline services and is today used for corporate and business services flying out of Portsmouth and for flight training.
