in 1975, a boeing 707 was leased from pelita air for flights between denpasar and tokyo but the route was turned over to garuda indonesia by the indonesian government. after 1977, the dc-3s were phased out in favor of the newer, more modern f27s. after this, the airline was unable to acquire other types of aircraft as the government placed restrictions on private airlines buying new equipment and it was not until the mid-to-late 1980s that the fokker 100 and the boeing 737-200 were introduced into the fleet.
