I believe EF is the accurate number. milecalc and GCM seem to overestimate mileage very slightly. I'm flying CX LAX-HKG tomorrow and checked on the stated distance. CX uses 7,248, which matches the distance stated by EF. milecalc and GCM say it's 7,260.

That said, you'll be slightly under the 100k needed if you book that flight.
Thanks! The question was what AA uses to calculate milage not CX - since I will be crediting to AA
