Francis E. Warren Air Force Base
Warren AFB is the oldest continuously active military installation within the Air Force, established in 1867 by the United States Army as Fort David Allen Russell. The facility came under United States Army Air Forces control on 1 June 1947, and United States Air Force (USAF) respectively on 18 September 1947 until now.
Cincinnati Municipal Lunken Airport
Today the old control tower is home to the Lunken Cadet Squadron of the Civil Air Patrol, and is the oldest standing control tower in the United States. The property also contains public recreation areas, including an 18-hole golf course, playgrounds, and walking/biking paths on the levee surrounding the airfield. In 2009 Ultimate Air Shuttle began operations at Lunken with a flight to Chicago–Midway, and has since expanded to four cities, including Chicago, New York, Charlotte, and Cleveland. Currently, many Cincinnati-area companies base their aircraft at the airport due to its proximity to downtown Cincinnati, but most airlines use Cincinnati/Northern Kentucky International Airport. Various proposals have taken place to add air service to the airport, including by Allegiant Air, which started operations at CVG instead, and Flamingo Air, which didn't happen. In 2018, a fixed based operator called Waypoint Aviation began operations out of a new 40,000-square-foot hangar at the airport.
