When I vacationed in south Florida in the 1970s I noticed around 1974 Mackey was adding Douglas DC-6s in their fleet
along side of their Convair 440s.I saw that most of their DC-6Bs had the registration that started with N37 which were
former United Airlines planes.From what I understand United repossessed a fleet of DC-6Bs from a scrapper for non
payment Did Mackey purchase those planes directly from United. Mackey also had a ex-American Airlines DC-6B-
N4354B which had more pointed prop spinners on the engines and also there was a Ex-Pan Am
6B N111DG a former
IGS plane. They also had a DC-6(not a B) N90705 ex-AA plane. Was Mackey the only airline in the USA to still operate
passenger DC-6s in the 1970s. Im sure when Mackey ceased operations in 1980 Those vintage DC-6s meant
the inevitable end at
FLL and MIA
