When I was eight years old, my family moved to New York City from St.Louis MO. My first experience of the "big Apple" was flying into New York City. I fell in love with three things that day: Airplanes, New York City, and JFK Airport.
We lived in Westchester County a few miles north of the Bronx, and every time I had a turn to pick a family outing, I would always pick going to JFK so I could spot all the unusual planes from around the world. That is how I became an airline enthusiast.
My favorite place to be was the TWA terminal, right when all the planes were getting in from Europe.
We moved out to California six years later in 1973 and I have lived out here ever since. In 1995, I drove my wife and sons back east for a sightseeing trip, and the number one item on my agenda was an afternoon and evening at JFK. It was a wonderful experience seeing the "hub of the world" (as I have always fondly referred to it) again.
Londoners would point out that Heathrow is equally a "world hub" if not more so, but of course I am an American, and I consider Kennedy America's original gateway to the world.
The airport does need several improvements to meet current air traffic demands. I only hope that in remodeling terminals, they will try to preserve the beautiful and unique architecture that defines so many of them, and if they have to build some new ones, that's great, but please keep them unique, not like most airports where you can't tell one terminal from the next. and from the outside, most modern terminals are very non-descript.
They also need to link terminals together at JFK by means of underground trains and walkways, so that passengers can make relatively painless interline connections. That is a must at for a "world hub".
