WORLD'S FIRST & LAST SERVICE
Delta flew the world’s first DC-9 service on November 29, 1965, with DC-9-14 Ship 105, from Atlanta to Memphis to Kansas City. Daily scheduled DC-9 service started December 8, 1965. Delta acquired the fifteen-foot longer DC-9-32 model in 1967.
Delta thought it had retired the last of its DC-9s on January 1, 1993, but a 2008 merger with Northwest Airlines brought Delta 97 more DC-9-30, DC-9-40 and DC-50 planes. When these DC-9s retired, that ended the commercial DC-9 service. Delta flew ceremonial retirement flights on January 6, 2014, and a final service flight on January 22, 2014.
