In 1957 there was a commercial flight 5 days a week from Saigon to Dalat operated by Air Vietnam utilising a Douglas DC-3. The flight continued from Dalat to Banmethuot and then other cities before reversing its route. By 1962 the frequency had increased to 2 flights per day. By 1969 the DC-3 planes had been replaced by DC-4s and an additional flight per day was added to the schedule. By 1972 the frequency was reduced to 1 flight per day utilising DC-3 and DC-4s.
