Salivating about AA getting its hands on NW so they can connect passengers through NRT is meaningless in a market where new transpac flights that overfly the Pacific are being added every year. The bottom line is that if AA can't make routes to Asia work from its current strong hub markets, there's no reason to think they would benefit from NW. All of NW's Asian service is via NRT right now as it is so they will have to spend the first 3 years of 787 deliveries rebuilding their nonstop transpac service to points beyond Japan. AA could do that right now if they could figure out how to make it work.
World, you're an intelligent guy; so how come you keep posting stuff like this? AA and its cheerleaders aren't salivating over the possibility of connecting pax at NRT. We're salivating over the possibility of gaining 29 weekly frequencies to CHINA. THAT's what's got everyone salivating. Unlike all the other destinations you list, China is a limited access market. Completely opposite of "open skies." Valuable in part because not everyone with an airplane is allowed to initiate service between the USA and China. To a lesser degree, same thing with NRT.
NRT? Still a lot of value in the NRT access (of which NW has a LOT). Fifth freedom rights? Most people understand that long range airplanes have lessened their importance. Still, NW and UA use their fifth freedom rights pretty extensively, so there must be some profit in doing so.
I'd suggest that there are routes from ORD that AA should be flying now including HKG, TPE, and ICN. US carriers can add segments beyond TPE and ICN with local traffic rights allowing AA to develop a pretty significant Asian route system with a relatively small financial commitment - if they can figure out how to make new routes work.
HKG? Very competently served by a superior foreign airline - Cathay - perhaps you've heard of them? Only benefit of AA metal to HKG would be the ability to upgrade. But if you're already buying J or F, you'd be certifiable to do it on AA metal v. Cathay Pacific.
TPE? Lots of codeshare service with EVA, which offers excellent service. AA tried SJC-TPE, and it might have eventually panned out if the terrorists hadn't devastated AA five years ago. UA is going to restart TPE; we'll see how well UA does.
ICN? Knock yourself out. Lots of ways for AA to route pax there, via JAL (joining the OW Alliance next year) and CX.
World - it's not about placing lotsa dots on the map. It's about making a profit on each and every long-haul flight. If you can't sell enough J and F, you don't fly it.
AA has a recent string of failures on long-haul flights, like ORD-NGO (lost the corporate contract to UAL); DFW-KIX (restarted this route but couldn't sell enough J and F); SJC-NRT (not enough J and F to make this work - UA owns Bay Area to Japan traffic). I'm sure there are others.
AA also has some recent winners, like ORD-DEL and ORD-PVG. Perhaps DL will hit home runs on many of its new long-haul flights. You'd better hope it does. If they work out - everyone looks brilliant. If they fail, that's a lot of 767s sitting around.
