You misunderstad my point, because of my explaination isn't good.
JAL said I can't JL ciredit partner miles soley based on booking class whatever price is paid.
I specifically asked CX's upgrade case.
JMB sevice center confirmed I couldn't earn any miles at all even I paid business class fare.
JMB service representative doesn' know what will happen in this case.
Because for JAL's own upgrade case, JAL explicitly says it is credited base on the original ticket. However, partner miles crediting, they say 'solely based on booking class whatever paid'.
So the question is, does CX tell JAL I flew at class D or class Z?
