I realize they don't fly there but would like to get as close as possible on AA and the rest on Oneworld carriers if possible. The switch from JFK- NRT to JFK-HND is complicating. I would like to upgrade as much of the trip as possible. I could fly into HND, spend the night in Tokyo and leave onward from their while going n either direction. Best I have come up with so far is JFK-HND, overnight in Tokyo and then onward to CNX by yet undetermined routing and then returning CNX - NRT -DFW - NYC.

Any other suggestions? And suggestions on the best way to get to CNX from Japan or possibly HKG? Thanks.
