(thanks Kiwi Flyer for your answers to my previous post.)

I have reworked my DONE3 ex-TYO itinerary and hope some of you might have insights on how to improve it before I call the RTW desk to make the changes.

New itinerary (flown segments in bold, the rest to be flown up until 08/2016):

NRT-xORD-JFK-LAX-xDFW-JFK-xDFW-LAX-xDOH-MAD-TXL-xDOH-FCO-HKG-KUL-xDEL-NRT

As you can see, I tried to maximize mileage accrual. I also dedicated time to assess all YQ surcharges/taxes on ITA. I was surprised by the high YQ surcharges on QR segments. I then learnt from other FT threads about using AA codeshares to minimize YQ and potentially get better mileage accrual as well (my understanding is that as AA PLAT I would get 50% COS bonus versus 25%, I believe.) So, to my questions:

1) I could not find AA codeshares for the new QR LAX-DOH flight starting in 2016, although AA has codeshares for several other QR flights, including my chosen DOH-MAD and DOH-FCO segments. Is it possible that AA will release a codeshare for the new LAX-DOH anytime soon or perhaps I did not properly look for it? I checked on ITA, EF, AA, as well as QR press releases at no avail.

2) I could not find an AA codeshare for the CX FCO-HKG segment, although many CX flights seem to have AA codeshares, including intra-Asia flights. Possible that I missed this one as well or is there another reason for its absence?

3) If securing AA codeshares is not possible for the above mentioned segments, would you have other routing suggestions for my connecting segments (prefixed with "x") in order to maximize miles and ideally keep YQ to a minimum?

Thanks for your help..! And apologies in advance if this should be posted on a different forum/thread, I thought that due the xDONEx rules and routing involved I should post here...
