I am definitely curious about the AA segments posting as distance based and there doesnt seem to be hard rule on it.
I am looking at doing the usual
TYO-DEL-HKG-JFK-LAX-DOH-LHR-DXB-LHR-HKG-SIN-TYO just for fun in D and need the CX segments marketed by AA (cx pitiful 25% earning doesnt appeal. do you guys have any more observations on the distance on AA marketed flights?
