John F. Kennedy International Airport
Facts on JFK
JFK airport opened in 1948 as New York International Airport but was commonly known as Idlewild (after the golf course it replaced); it was renamed John F. Kennedy International Airport on December 24, 1963, just over a month after President Kennedy's assassination.

The freshly renamed Kennedy Airport was first assigned the code KIA -- but in 1968 it was changed to JFK specifically to avoid the unfortunate association with "killed in action," a term with grim resonance during the Vietnam War era.

By 1954, Idlewild (as JFK was then known) already had the highest volume of international air traffic of any airport in the world, and today JFK remains the busiest international commercial gateway in North America.
