He wasn't asking about city-pairs that are actually flown, just hypothetical city pairs. Most of the ones mentioned above are not, in fact, flown, and none of them are non-stop. I guess AKL-LHR is the longest one that is actually flown, although not, of course, non-stop. Keep in mind the longest possible (great circle) route would be something like 12,500 mi or a little bit more, so 11, 404 is pretty close.

Well, I was talking about major city-pair distances not necessarily flown. JAL flies NRT-JFK-GRU 5 times a week I believe. I find it interesting that some routes that appear far on a flat map are actually not that far via the great circle route.
