I am not a New Yorker, so I really do not grasp the preference for JFK for international routes. Every time I've been there, I've just hated it. Burning UA miles, I've always had to fly DCA-LGA on US, and then cab to JFK for the international flight. The one exception involved an ICN-JFK-IAD, using UA's sporadic IAD-JFK service - flight was delayed to the point that I had 6 hours in the lounge. (I will allow for how SFO and LAX have superior service to JFK). But upon Singapore's exit from EWR this fall, and US's upcoming exit from SA, JFK will become a terrible transfer point for SA pax. Of course, many SA pax on Turkish, LOT, Singapore, TACA, South African, Copa, TAP, ANA, China, Asiana, and Avianca may only need to go to New York. But at what point do these SA partners opt for the transfer pax opportunities to be had by moving to EWR? Just seems like a missed opportunity.
