I am currently AA PLT and CX Silver.
So here is my travel plan for this year.
I will have 1-2 trips from TPE to US, also 5-7 trips intra-asia from TPE.
My travel is always deep discount Y.
So for trip to US, I have the choice of AA and CX.
For the trip intra-asia, I have the choice of CX.
What program should I credit my miles?
For AA, I can get 100% bonus miles if I fly AA or CX H fare. But I will get nothing for intra-asia fare.
For CX, I can get all the miles, but I will not have 100% bonus miles.
I can try to do both, which means using AA for the trips to US and using CX for intra-asia.
Any recommendations?

Thanks
