The other issue for US now AA is the alliance. With Star they were pretty strong, I used them for this reason. AA have always had the worse service across the Atlantic, even internally in USA they were poor.
The China service just seems to get further away. HU and APD are not exactly helping. Should be courting CA to PEK.
Terminals. Great news they are finally starting to do something, but years too late. Hopefully they can build quickly and sort it all.
