 In November 1959, Eastern Air Lines opened its Chester L. Churchill-designed Terminal 1 at New York City's Idlewild International Airport (later renamed John F. Kennedy International Airport).In 1960, Eastern's first jets, Douglas DC-8-21s, started to take over the longer flights, like the non-stops from Chicago and New York to Miami.The DC-8s were joined in 1962 by the Boeing 720 and in 1964 by the Boeing 727-100, which Eastern (along with American Airlines and United Airlines) had helped Boeing to develop.
