Umm, this is MAD-DOH-HKG RT? 16855/5 is 3371, + 350*4 is the 4771 in your print screen. They got the 4*350 right but probably still missing some YQ since the final price is 4749. So you'll end more with more than 5000 which is what you would have gotten if you booked it through QR.
Btw not sure what emerald benefits you get flying QR as OWE as supposed to OWS since the J lounge is better than the Emerald lounge?
QUOTE=Wolkenwandler;37506912]Thank you for the clarification. How about a MAD–HKG round trip in J Optima (outbound on IB and return on a QR codeshare)? However, this is also not an ideal connection, as separate tickets would need to be purchased for FRA–MAD and HKG–UNK, and baggage would have to be rechecked at both airports.
