In polar (Alaska/Siberia) latitudes during the peak of summer, sunrise is NNE and sunset is NNW. I've done the "supposedly" red-eye LAX-PEK in June, and picked the right window on purpose, just to see the sun to the NORTH, albeit just for a few seconds covering head and body with the blanket next to sleeping neighbors.
