Title says it. Taking this flight as a continuation of our CX flight JFK to HKG. 701 continues on to BKK. First Class award ticket but second leg is an Airbus 333 where the highest class is Business. Thrilled to see on ExpertFlyer that it has been changed to a 747 with First Class. Called AA to have them change that second leg to First Class and they informed me that it's an error - still a 333. Cathay website confirms this. What gives???
