No one knows the exact answers but the airlines, though you are most likely looking at the big three being New York City/Newark, Los Angeles, and Miami. As the largest gateways to each of the three major international travel regions (Europe, Asia, and Latin America/Caribbean, respectivley), they not only provide strong orgin & destination traffic, but are the only connecting points to many destinations.
For example, Miami has the US' only non-stops to Cochambaba, Bolivia, Manaus, Brazil, and Cali, Colombia, among many others. Los Angeles has the only non-stops to Harbin, China, Melbourne, Australia, and Canton, China, while New York City/Newark is the only way to get non-stop to Nice, France, Athens, Greece, and Oslo, Norway, among other examples.
