Otherwise to minimize taxes and surcharges, the only way is to look at codeshares. Gvernment taxes are set, you can only minimize those by changing your route/stopovers.

I think the consensus if I understand it correctly is that the base fare and taxes do not change but by changing the plating carrier to Qatar the YQ/YR fuel surcharges are lower for some reason that I can't fully explain.
