I understand there are international flights that must take off, but it seems that every weekend domestic flight passengers have nothing but hours of delays, often waiting on the plane while taxiing, before they arrive at their destinations. As I type this, a flight from NYC to Rochester that was supposed to take off at 10pm is still on the tarmac. A couple weeks ago I was treated to an eight hour wait before my plane arrived. Blame the airline if you want, but it’s really an issue with JFK.
