sharing my experience on the topic, I for one, started my first RTW ex-CAI without considering the FFP.

But, as I lurk along the forum, and learning through the post, naturally, I want to try to maximize the FFP status.
For my own ticket, I will have to mix between MH and QR, because i want to maintain my Enrich Platinum via MH, then the balance to go with QR.
While for my wife's ticket, as a newbie, the route I book was un-optimized, but even with that, using the Qpoints calculator, my wife could get close to 450 points, if I credit all her flights to QR. Thus, I am now trying to tweak and see if can get her to 600 Qpoints.

If I understand correctly from the past 2 days discussion,
1. Say, I am taking a MH flight from KUL - NRT
2. The same flight is marketed by QR.
3. Using the Qpoints calculator,
- If take MH and credit to QRPC - I got 30 Qpoints
- If I take MH but use codeshare by QR - then I got 81 Qpoints.
Am is my understanding correct?

I found out through luck that when I was messing with my seat selection at QR page, I realize I can select my seat for KUL - NRT in the same page, which leads me to believe there is codeshare with QR in this flight.
I further investigate in QR page, by searching the flight,
- when I search KUL - NRT, it says no such flight
- when I search DOH - NRT, then the MH flight with QR code shown up as connection.

My question is, is there a reliable way to find what's the codeshare available for other flights?
