QR flies to all of the major airports in the UK with big planes with lie flat business, not the A319s and A320s that AY flies there with EuroBusiness.
Fair enough. My sense was that the OP wasn't seeking to maximize the flown mileage in what was a very high-speed RTW, hence my more direct routing to get from Tokyo to Edinburgh. I also used LHR-DFW in order, should the OP choose, to book the RTW ticket using American Airlines, potentially reducing (perhaps significantly) the amount paid for various fees including YQ/YR surcharges. Flying LHR-DFW on AA metal ought to be sufficient incentive for the AA RTW desk to issue the ticket. But of course if the OP has the time and inclination to use the RTW ticket to maximize Avios, tier points etc., there are LOTS of options to pursue, mainly in North America.
