Cincinnati/Northern Kentucky International Airport (IATA: CVG, ICAO: KCVG) is located in Hebron, Boone County, Kentucky, United States and serves the Greater Cincinnati metropolitan area. The first airplane landed at the airport January 10, 1947. The airport's code, CVG, comes from the nearest major city at the time of its opening, Covington, Kentucky, although the airport authority likes to say it stands for "Cincinnati Very Good."

The airport has 3 terminals. Terminal 1 closed down on January 16, 2007. It is currently being used by the airport for Administrative offices. Until recently it was served only by US Airways Express. It was announced the airline would be relocated to the renovated Terminal 2 within the next year so that the airport could curtail its operating costs by closing Terminal 1. American Airlines, United Airlines and US Airways all operate in Terminal 2. Terminal 3, built specifically for and by Delta, has 3 remote concourses connected by an underground tram and bus system. Terminal 3 is served by Delta, its regional affiliates, and Skyteam partners Continental, Northwest, and Air France. Terminal 3 is the only one with US customs offices, and is therefore used by USA 3000, and until recently, Transmeridian Airlines.
