The airport that I do not want to go through again, when I return from Europe, is JFK (New York City Kennedy airport). Waiting to show my Passport to an immigration officer there did not take much time. But walking to the Flight departure Gate for my flight to an other airport in the U.S.A. was a difficult experience. I was nearly late at the Gate for that flight. After showing my passport, I was required to walk to an other place for my bag to be opened and its contents examined. (I do not know why). My bag was put on a very long conveyor belt, going to the airline's baggage room, but I experienced difficulty going to the Flight departure Gate. The man at the place for examining bags gave me directions for walking to the Flight departure Gate, but his directions were not very good. Following his directions, I (and several other people) arrived at a wall (a side of that building). A fence was between me and a door to the outside of the building. I walked around to that door, and outside, and walked across a street that has cars on it. (The man giving me directions did not say I will walk across a street). To an elevator for going up. In the elevator I was squeezed in with many people who were in a hurry to get to their departure Gates on time for their flights. In that airport, in the first building that I was in, there were no signs directing people to Flight departure Gates. And, flying from the JFK airport, to a destination in Europe, my airplane lifted off from the runway at a time that was one hour later than the scheduled time for its departure. JFK airport is not the only airport where that happens. The Chicago O'hare airport is notorious for having airplanes lift off from the runway at times that are very much later than the scheduled times for departure.
