Comair is a wholly owned subsidiary of Delta Air Lines based in unincorporated Boone County, Kentucky, United States, west of Erlanger and south of Cincinnati-Northern Kentucky International Airport, an airport serving Cincinnati, Ohio.[1]

Comair is one of the world's largest regional airlines and, with over $1 billion in annual revenue, would be considered a major airline carrier except for the fact that its aircraft seat less than 100 people. Operating under the brand name Delta Connection, Comair operates passenger services to a large number of destinations in the USA, Canada, Mexico and the Bahamas.
