The first intruder into Boeing/Airbus domination is McDonnell Douglas MD-80. Since venerable MD-80 is out of production, in a few years it will no longer have a place on this list. But for now, it still holds its own. Produced for 20 years, from 1979 to 1999, MD-80 was derived from DC 9. It was later developed into MD-90 and Boeing 717. There are currently 426 MD-80 in service with 28 airlines, 180 of them with Delta Air Lines.
