Just spoke to BA agent today, she's trying to get my booking sorted.
My route is as follow:
LHR-DXB-HKG-DPS-HKG-NRT-HKG-NYC-LIM-EZE-GRU-SCL-MIA-CUR,AUA-SFO-NYC-BGI-MIA-MEX-LHR
(53547 miles)
Only LHR-DXB is dated all others are open-date.

So now i wonder which FFP.

The trip should be finished around march or so, thinking of doing the AA PLT challenge once i leave from HKG to NYC (Which should be beginning of January)

But my question is what should i credit the other segements too?

I have a few CX flights here and a few BA.

I fly a lot back and forth to Asia from Europe, so it makes a bit of sense of doing Asiamiles, but not sure... need your help
Is asiamiles useful for upgrades etc?

Is there any FFP which earns 100% of miles for BA and CX in L ?
