It's irrelevant where UA flies to in this case. Far more premium international flyers are coming in on proper premium airlines - BA, ANA, SQ, CX, EK etc - not on a third-rate airline.
You can see the difference in international arrivals at JFK vs EWR - it's a huge differential. You can also see it in the relative frequencies of airlines who do fly into both airports: BA probably has 3x as many JFK flights than EWR (even without the AAJV); VS is pulling out of EWR altogether; CX has 4x the number of JFK flights than EWR.
