Delta Air Lines Inc., which is based in Atlanta, has about 350 regional jets and plans to reduce that to 125 within two years. Operating regional carriers has become more expensive while customers have been demanding roomier planes.
Comair represents only about 1 percent of Delta's flying, so the closure won't result in significant changes to Delta's network.
Comair, which is based in Cincinnati, was founded in 1977. It started operating as Delta Connection in 1984. According to its website, the regional airline has 1,700 employees.
Delta says the move won't result in a reduction of flights planned at Cincinnati/Northern Kentucky International Airport.
