at the airport. In 1947, the Town of Islip offered the airport to the Port of New York Authority (now the Port Authority of New York & New Jersey). The offer was rejected because of the airport's location outside of the port region. Commercial service era In 1960, Allegheny Airlines was the first scheduled passenger airline at Islip, flying to Boston, Philadelphia, and Washington, D.C.. The March 1961 Official Airline Guide lists five weekday Convair 440 departures: a nonstop to Washington National, one to Baltimore, and three flights direct to Boston via several stops. The General Douglas MacArthur Terminal was completed in 1966. In 1967 Mohawk Airlines began two Fairchild Hiller FH-227 flights a day, to Bridgeport and Albany and beyond with one flight continuing to Toronto. By 1969 Mohawk was flying BAC One-Elevens nonstop to Syracuse. In 1972 Mohawk had nonstops to Albany with direct service to Buffalo and Rochester. Mohawk would soon be merged into Allegheny Airlines. In 1971 American Airlines began flying nonstop Boeing 727-100s to Chicago O'Hare Airport. By 1974 Allegheny had started BAC One-Elevens and McDonnell Douglas DC-9-30s nonstop to Albany and Washington D.C. National Airport, and direct jets to Burlington, VT, Cincinnati and Detroit. Allegheny continued operating Convair 580s nonstop to Albany, Boston, Bridgeport and Washington D.C. in addition to direct Convair 580s to Buffalo and Rochester. Allegheny would be renamed USAir, which then became US Airways, with these respective airlines operating service into the airport for many years before US Airways was merged into American.
