The airport was a vital link to the Samoan Islands until the runway at Faleolo International Airport in Independent Samoa was improved and lengthened to handle larger than Boeing 737 type aircraft in 1984. With a population that is 3.5 times greater than American Samoa plus greater emphasis that was put on tourism growth, international airline traffic particularly from Australia, New Zealand and the South Pacific island countries began to shift from Pago Pago to Faleolo airport. Airlines with flights from the US to Australia and New Zealand also started utilizing aircraft that did not require a refueling stopover in Pago Pago. By the late 1980s and due to heavy competition and economics, only one passenger air carrier (Hawaiian Airlines) remained to serve the Pago Pago trans pacific route.
