Further, it appears that the fare selected is based on the "dominant" carrier, which seems to be the first overwater/long-haul carrier OR the first carrier. For me here's what I saw:

CAI-xDOH-DXB-xLHR-PMI-xMAD-DFW-GRU-JFK-xHKG-DXB - priced out at USD $6K+
but changing it to
CAI-xLHR-PMI-xMAD-DFW-GRU-JFK-xHKG-DXB (and ensuring that I only use BA, IB and CX for the over water segments) - priced this at $3442. (validating on CX)

If I used the AA flight from MAD to DFW - it prices using AA base fare (>$7k), if I use QR in the first segment it uses QR base fare (>$5k).

With these restrictions in mind - I was able to get the AA desk to price the itinerary at around $3,800 (validating/ticketing on AA) - higher YQ and taxes but perhaps worth it to deal with the AA RTW.

Good luck

And the tool is pricing the base fare with a difference of several thousand dollars (*unless* I have CAI-LHR-BOS as opposed to CAI-AMM-DOH-BOS at the beginning of the ticket, in which case it prices the tickets ending AKL-DOH and AKL-SYD-SIN-DOH the same.) Looks like a bug with the RTW builder to me.
