There is nothing challenging at all about plating on QR stock, you just have to use a travel agent. But as others have pointed out TA fees aren't so high that you'd not want to do it that way. You'll save tremendously on YQ / YR fees in most cases. There might even be other plating carriers that could work out better than QR on fees, but your itinerary doesn't include any segments on them so wouldn't matter in this case. This is where a travel agent who has spent a little time to play around with different options in the GDS is so valuable. You'll pay them a token amount compared to the savings in YQ / YR quite often.
