I don't see a JFK route map, but didn't AA serve HKG from there to build on the partnership with CX?
AFAIK in modern times AA never served HKG until DFW started with the 77W's around 2014/2015.
In the 90's AA service to Asia was basically NRT only from DFW, the aforementioned SJC, and don't forget about SEA.
Oldest AA timetables I have are from '92 and '95.
