Only passenger on DL computer partner flight
Years ago I flew PHL to BOS on Business Express. I was the only passenger on a small Business Express regional jet (could even have been a prop-jet). There was no co-pilot so the pilot asked if I'd like to sit up front in the co-pilot's seat, which I did. We flew directly over JFK and I told the pilot I was surprised that we were allowed to do so, given the huge amount of traffic at JFK. He said that while JFK is indeed a very busy airport, none of the activity at or very close to JFK takes place at my flight's altitude. I then thought, of course that's true.
