Pre-jet service

Pago Pago International Airport and the original Tafuna Airfield military facilities were first used for commercial trans pacific air service in November 1946 when Pan American Airways resumed service from Honolulu to Australia and New Zealand. Pan American utilized Douglas DC-4s, and eventually upgraded to Douglas DC-7C aircraft in 1956 (when Pago Pago International Airport was upgraded as a commercial airport) for its Honolulu / Canton Island / Pago Pago / Nadi / Auckland and Sydney route. This service was conducted using the outbased DC-7C aircraft Clipper Seven Seas N743PA^[13] and Clipper Pacific Trader N744PA ^[14] on the route and continued until November 1965.

It was also used for inter island air service between Faleolo, Western Samoa and Pago Pago in 1959 by newly formed, Apia-based Polynesian Airlines and short-lived, Pago Pago-based Samoa Airways using ex-military Douglas C-47B-45-DK (DC-3D) type aircraft.

Tasman Empire Airways Limited, or TEAL, the predecessor to what is now Air New Zealand, offered Douglas DC-6 (eventually using Lockheed L-188 Electra aircraft in 1960) flights from Nadi to Pago Pago^[15][16] and onwards to Tahiti in 1954 as part of its Coral Route Service.

The Jet Age

Pago Pago International Airport went through major re-construction in 1963 under the U.S. President Kennedy administration. The WW II military-era runway designated 14/32 was converted to a taxiway and ramp area, and a new runway was constructed and designated 05/23 with a paved length of 9,000 feet (2,743 m) and width of 150 feet (46 m).

The terminal buildings at the airport were dedicated on November 23, 1965. Dignitaries attending included Senator Henry M. Jackson, Chairman of the Senate Committee on Interior and Insular Affairs; Representative Michael J. Kirwan, Chairman of the House Subcommittee on Appropriations, Interior and Insular Affairs; Malietoa Tanumafili II; and Prince Tāufaʻāhau Tupou IV, Prime Minister of Tonga.^[17]

Runway designation 09/27 which was the primary runway for commercial air service in the 1950s and early 1960s was deactivated after the newer, longer runway 05/23 was open for aircraft flights. Pago Pago International Airport was opened to jet service in 1964 to stimulate tourism and a new local economy.

Trans Pacific jet service and height of commercial aviation

South Pacific jet services between Sydney (Australia), Auckland (New Zealand), Honolulu (Hawaii) and Papeete (Tahiti) were first offered by Pan American World Airways in 1964 using Boeing 707 aircraft. Air New Zealand, which was already flying the Auckland / Nadi / Pago Pago / Papeete route using Lockheed L-188 Electra aircraft shifted to Douglas DC-8 aircraft in November 1965. In 1970 American Airlines^[18] began flying the Honolulu / Pago Pago / Sydney route using Boeing 707 aircraft.^[19] UTA French Airlines began Douglas DC-10 service in 1975 between Noumea, New Caledonia and Papeete, Tahiti via Pago Pago. Continental Airlines also began DC-10 service from Honolulu to Sydney and Auckland via Pago Pago in 1979.

Pago Pago International Airport went through its peak in aviation between 1975 and 1985. During this period Pan American (using Boeing 747s), Air New Zealand (using DC-8s), UTA French Airlines (using DC-10s), Continental Airlines (using DC-10s), Hawaiian Airlines (using a DC-8), South Pacific Island Airways (using Boeing 707s), Samoa Air (using a Boeing 707), Arrow Air (using a DC-8), Air Nauru (Boeing 737 and Boeing 727), and Air Pacific (using a BAC One-Eleven) were all plying the South Pacific via Pago Pago. One could travel between Pago Pago and Honolulu for an airfare of US$99 one-way.

Cargo commercial aviation

Towards the end of its peak commercial passenger aviation period, Pago Pago International Airport also became an ideal refueling stopover for cargo carriers due to the low cost of fuel and landing fees at the time. Cargo carriers such as Kalitta Air, Evergreen International Airlines, and Polar Air Cargo would provide at least daily Boeing 747 cargo flights to Pago Pago from the US and from Asia Pacific between 1990 and 2006.

Downturn in airport usage and travel

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.

Runway and facility expansion

Runway 09/27 was the primary commercial runway for aircraft in the 1950s and early 1960s. The runway was deactivated after runway 05/23 was constructed and activated in 1964. In the mid-1970s, runway 09/27 was rehabilitated, repaved and reactivated as runway 08/26 with 3,800 feet (1,158 m) (length) by 100 feet (30 m) (width) to function as a secondary runway and taxiway. Runway 08/26 is widely used today by air taxi operators flying to Apia (Fagali'i and Faleolo), Ofu or Tau.

The Departure and Arrival terminal also went through a major expansion in the mid-1970s where buildings and space was doubled in size to handle more passengers.

To facilitate aircraft with large payload requirements and long distance flights, runway 05/23 was expanded in early 2001 from an original runway length of 9,000 feet (2,743 m) to the current 10,000 feet (3,048 m).

On October 13 and 19, 2009, the world's largest and heaviest aircraft, the Antonov An-225 landed at Pago Pago International Airport to deliver emergency power generation equipment^[20] during the 2009 Samoa earthquake and tsunami.
