I was able to find the flights on kayak.com (under Cathay Pacific). The first segment is codeshared... I was also able to find a fare on Dragonair only for both segments. See below. This means that it is indeed a paid published fare, correct?

So has the way AA been processing these awards changed in the last few months? Last time was also Dragonair to HKG then CX to Taipei.
