I like this schedule too !! I too often connect via LAX red-eye to NYC/east-coast...this new schedule sounds much better, no need to fly AA transcontinental anymore...
on the point about the plane sitting in JFK for 12+ hours...just a very wild thought, but, it doesn't give it enough time to fly JFK-LHR-JFK, right ? or, HKG-JFK-LHR-HKG with one plane and HKG-LHR-JFK-HKG with another ? wish CX would really start JFK-LHR v.v. soon...
