Hello all. Happy holidays!

We have an upcoming trip to Taiwan. The starting point is San Francisco and the destination will be Taipei, Taiwan. Here is our itineraries (on 3 different PNRs)

SFO-LAX (AA domestic) Stay over one day in LA
LAX-NRT (AA first) Stay over one night near Narita
NRT-TPE (CX business)

From CX website, it states that the baggage allowance is limited to 66lbs per person when we fly business class (intra Asia routes). Even though we will fly from SFO, since we will stop over one night at NRT, we will need to follow the intra Asia baggage allowance, right? I am a OneWorld Emerald and am I entitled to an additional allowance?

Thank you!
Chan
