The airport opened on March 21, 1927, as John Rodgers Airport (aka Rodgers Field), after World War I naval officer John Rodgers. It was funded by the territorial legislature and the Chamber of Commerce, and was the first full airport in Hawaii; aircraft had previously been limited to small landing strips, fields, and seaplane docks. From 1939 to 1943, the adjacent Keehi Lagoon was dredged for use by seaplanes, and the dredged soil was moved to HNL to provide more space for conventional planes. The U.S. military grounded all civil aircraft and took over all civil airports after the attack on Pearl Harbor, and Rodgers Field was designated Naval Air Station Honolulu. The Navy built a control tower and terminal building, and some commercial traffic was allowed during daylight hours. Rodgers Field was returned to the Territory of Hawaii in 1946. At the time, at 4,019 acres (1,626 hectares), it was one of the largest airports in the United States, with four paved land runways and three seaplane runways. John Rodgers Airport was renamed Honolulu Airport in 1947; "International" being added to the name in 1951. Being near the center of the Pacific Ocean it was a stop for many transpacific flights. By 1950, it was the third-busiest airport in the United States in terms of aircraft operations, and its 13,097-foot (3,992 m) runway was the world's longest in 1953. In February 1954, flagship carrier of Japan, Japan Airlines began the direct flight service to Honolulu on its flights between Tokyo and San Francisco. In summer 1959, Qantas began the first jet service to Honolulu on its flights between Australia and California. Qantas introduced these jet flights with Boeing 707 aircraft operating a routing of Sydney – Fiji – Honolulu – San Francisco. Aeronautical engineer and airline consultant Frank Der Yuen advised in the design of the original building and founded its aerospace museum. The original terminal building on the southeast side of runways 4 was replaced by the John Rodgers Terminal, which was dedicated on August 22, 1962, and opened on October 14, 1962. From 1970 through 1978, the architect Vladimir Ossipoff designed a terminal modernization project that remodeled this terminal and created several additions, which included the Diamond Head Concourse in 1970, the Ewa Concourse in 1972, and the Central Concourse in 1980. Pan American World Airways (Pan Am) used Honolulu as a transpacific hub for many years, initially as a connecting point between the West Coast and Polynesia (Fiji, New Caledonia, and New Zealand) in 1946, followed by service to Japan and China through Midway Island and Wake Island from 1947. By 1960, Pan American was serving the airport with Boeing 707 jets. Pan Am flight number 1, operating a 707, flew a westbound routing of San Francisco – Honolulu – Wake Island – Tokyo – Hong Kong and continuing on to New York City via stops in Asia and Europe. The airline also operated nonstop 707 service to Portland, Oregon (continuing to Seattle) and Los Angeles. Pan Am also had direct 707 flights from Honolulu to Calcutta, Guam, Jakarta, Karachi, Manila, Rangoon, Saigon, and Singapore in 1960. United Airlines was flying nonstop Douglas DC-6 "Mainliner" service from San Francisco in 1947 and by 1961 was operating Douglas DC-8 jet service nonstop from Los Angeles and San Francisco with direct one-stop DC-8 flights from both Chicago and New York City. British Commonwealth Pacific Airlines (BCPA) began serving the airport during the mid-1940s with Douglas DC-4 aircraft flying a routing of Sydney – Auckland – Fiji – Canton Island – Honolulu – San Francisco – Vancouver, B.C. In 1950, Northwest Airlines was operating nonstop flights from Seattle with Boeing 377 Stratocruiser propliners; by 1961, Northwest was flying daily Douglas DC-8 jet service on a round trip routing of New York City – Chicago – Seattle – Portland, OR – Honolulu.
