Possibly an interesting option as one who travels from LHR to AKL occasionally. I could not understand why its 18 or more hours. DOH to SYD is 14 or slightly less. SYD to AKL is 3 hours or a bit less. So I would have thought a flight DOH to AKL would be approx. 16 (still a long flight) or is it that the plane is slower through the journey from extra fuel (doesn't sound right)
