Northeast Airlines, a major east coast air carrier, provided scheduled airline service throughout the 1950s and 1960s until 1972, when it was acquired by and merged into Delta Air Lines, which in turn then ceased serving New Bedford several years later. In 1960, Northeast was operating Douglas DC-3 aircraft into the airport with nonstop service to New York LaGuardia Airport, Boston and Martha's Vineyard. By 1969, Northeast had introduced larger Fairchild Hiller FH-227 turboprops on nonstop flights to New York LaGuardia, New York JFK Airport and Boston. Northeast then introduced jet service and was operating McDonnell Douglas DC-9-30 jetliners nonstop between New Bedford and New York LaGuardia Airport in the fall of 1970 with two round trip DC-9 flights a day. Following its acquisition of Northeast, Delta continued to serve New Bedford with Fairchild Hiller FH-227 turboprops inherited from Northeast on nonstop flights to New York LaGuardia and Boston during the early and mid-1970s.
