Tri-State Airport (IATA: HTS, ICAO: KHTS, FAA LID: HTS) (Milton J. Ferguson Field) is a public airport in Wayne County, West Virginia, United States, three miles south of Huntington, West Virginia, near Ceredo and Kenova. Owned by the Tri-State Airport Authority, it serves Huntington; Ashland, Kentucky; and Ironton, Ohio. It has heavy use for general aviation, and after the withdrawal of Delta Air Lines in June 2012, it was down to two airlines, one of which provides nationwide connecting service. In addition, there is one cargo airline flying to the airport, for a total of three commercial airlines serving it. On August 2, 2021, a federal subsidy was announced to subsidize flights to Washington-Dulles and Chicago-O'Hare airports. It is not yet known which airline will operate the flights. Federal Aviation Administration records say the airport had 115,263 passenger boardings (enplanements) in calendar year 2010, 10.9% more than 2009. The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021 categorized it as a non-hub primary commercial service facility. The first airline flights were Piedmont DC-3s around the end of 1952; Eastern and Allegheny arrived in 1953. Eastern left about the end of 1972; Piedmont and Allegheny remained through the 1989 merger. The first jets were Piedmont 737s in 1969 (the runway was then 5280 feet). Eastern Airlines provided jet service beginning July 1, 1968 using a DC-9 jet.
