The McDonnell Douglas MD-80 is a family of twin-engine, short- to medium-range, single-aisle commercial jet airliners. The MD-80 series were lengthened and updated from the DC-9. The airliner family can seat from 130 up to 172 passengers depending on variant and seating configuration.
The MD-80 series was introduced into commercial service on October 10, 1980 by Swissair. The series includes the MD-81, MD-82, MD-83, MD-87, and MD-88. These all have the same fuselage length except the shortened MD-87. The MD-80 series was followed into service in modified form by the MD-90 in 1995 and the MD-95/Boeing 717 in 1999.
Douglas Aircraft developed the DC-9 in the 1960s as a short-range companion to their larger DC-8. The DC-9 was an all-new design, using two rear fuselage-mounted turbofan engines, and a T-tail. The DC-9 has a narrow-body fuselage design with 5-abreast seating, and holds 80 to 135 passengers depending on seating arrangement and aircraft version.
The MD-80 series was the second generation of the DC-9. It was originally called the DC-9-80 series and the DC-9 Super 80 and entered service in 1980. The MD-80 series was then developed into the MD-90 entering service in 1995. The last variant of the family was the MD-95, which was renamed the Boeing 717-200 after McDonnell Douglas's merger with Boeing in 1997.
The DC-9 family is one of the most successful jet airliners with a total of over 2,400 units produced; it ranks third behind the second place Airbus A320 family with over 4,000 produced, and the first place Boeing 737 with over 6,000 produced.
