I htink the Arctic Circle routes are beautiful. Glaciers, wild coastlines, mountains, ice pack, and most of all the aurora! And there's at least some traffic and even radar coverage over parts of it. The Southern Ocean routes, OTOH, are water all the way. Auckland/Santiago - 11.5 hours, over water. One flight a day. Ok, narita/LA is all water also. Anyway, the video is fascinating!
