If the final destination or the originating departure city is changed, then the OP can be charged $100.00. He doesn't have to redeposit miles and reissue a new award for the higher inflated cost awards we now have today. Many AA CSRs don't know this and just come up with their own rules, individually. The older, better, awards allows for 2 stopovers in HKG and 2 stopovers at a North American connection city. Now that AA is e-ticketing, the paper ticket will be replaced with an e-ticket and the paper ticket will have to be surrendered for any change, including a change in connecting. If no change, the OP can use the paper ticket when flying.
All of CXs award seats are either taken, blocked or looking for revenue passengers at this time for May in JFK. However, something could be available near the departure date, so inquire around then, but don't expect anything. CX would rather use those seats for MP and Emerald members in paid J, because someone else will pay for J. The same for J from Y as well. I hope AA gave you a seat in Z class (not U) for your JFK-LAX flight in their 3-Class 762. I wanted to do the same thing, but am also booked in a similar JFK-LAX-HKG itinerary and plan to use the LAX routing, just to experience what AA can give me in a Z on a 762.
