May 26, 2020 / Delta Airlines (DL) will end MD-88 and MD-90 operations on June 2. The last MD-88 flight in the carrier’s colors will be DL88 from Washington Dulles to Delta’s main hub at Atlanta Hartsfield. Earlier that morning, flight DL 90 will depart Houston Intercontinental and will land in Atlanta, putting an end to the type’s history with the airline.  Once on the ground in Atlanta, the aircraft will join several other MD-88s and MD-90s as they fly to Blytheville, Arkansas, where they will be officially retired from the fleet. The first MD-88 entered DL’s fleet in March 1987 and the carrier operated a total of 97 of the type. The first MD-90 arrived in February 1995 and a total of 58 have been operated by the Atlanta-based carrier. The retirement of the two type from DL’s fleet will mean the end of MD operations by a major US airline, although Delta keeps in service a fleet of Boeing 717, once called MD-95.
