I'll be the first to admit that I'm an amateur when it comes to airline strategy _and_ I think I've seen reference to impediments to JAL joining oneworld, but:

AA's beefing up service to NRT (JFK-NRT, a second DFW-NRT instead of DFW-KIX, next year's LAX-NRT, etc.) makes me wonder if they're planning to do more with JAL, if not welcoming JAL to oneworld. (Yeah, I know that they axed SEA-NRT, but that could have accompanied SEA's transition to a "seasonal" destination).

Any thoughts?
