John F. Kennedy International Airport [SEP] Early operations
The first flight from Idlewild was on July 1, 1948, with the opening ceremony attended by then-U.S. President Harry S. Truman. The Port Authority canceled foreign airlines' permits to use LaGuardia, forcing them to move to Idlewild during the next couple of years. Idlewild at the time had a single terminal building; by 1949, the terminal building was being expanded to . Further expansions would come in following years, including a control tower in 1952, as well as new and expanded buildings and taxiways. Idlewild opened with six runways and a seventh under construction; runways 1L and 7L were held in reserve and never came into use as runways.
