Isn't SIN-UIO the longest possible? I think I read somewhere that Singapore and Quito, Ecuador, are exactly opposite (polar opposites) nearest to the equator... which would be the longest possible great circle.
SIN-UIO, 10649 nm
AKL-GIB doesn't look right... If you plug in GIB-AKL, although it shows 10749 nm, I think that is an error. I did a straight-line great circle mapping on a globe, and it doesn't even go near Antarctica.
Here's the great circle line I ended up with AKL-GIB (roughly):
Cook Islands (N.Z. territory)
east of Mobile, Alabama, US
Cape Hatteras, North Carolina, US
north of Terceira, Azores (Portugal territory)

AKL-GRZ is 10743 nm, and also has a route much more like what I would approximate for AKL-GIB.
AKL-GIB the other way, by my estimate:
just south of MLB
northern edge of the Maldives
ashore on Africa east northeast of Salalah, Oman
just north of Medina, Saudia Arabia
just south of Alexandria, Egypt
just south of Sfax, Tunisia

Like said before 10786 is the unbeaten record of AKL-OZP (Moron, Spain).
Isn't it always shortest over the poles if the places are polar opposites, and in fact that any direction would come out the same if flown in a straight line (Look at the poles themselves, any direction you go from them, and you will end up at the other one).
