Just as an aside, if the SJC-TPE route remains as successful as is suggested, then AAL may well wish to expand its presence in that market. Currently, only CAL flies nonstop from TPE to JFK, although it can't do so on the return. It would be interesting to see how the 777 fares.
Also, AA has an advantage in that, not being a Taiwanese carrier, it could benefit from the new polar routes over China. I don't think/know if CAL is allowed to use these. (Then again, if the flight were bound for Taiwan, the Chinese might object?)
