Not to mention with today's long range aircraft, stops I'm sure are becoming less than before. Narita will always be an Asian hub so I doubt points to Asia will change much. I know there are direct flights to Hong Kong, Beijing, and Seoul. Layovers are becoming less frequent. I remember Miami being a big pit stop for all points to Latin America. Now they go directly from New York, Houston, Dallas, Atlanta. From Asia and to Asia, I've gone directly from SFO, SEATAC, DETROIT, ORD, LOS ANGELES, EWR, HNL. Seatac is the only place I've never overnighted or visited.
