Why do planes do not fly over the Pacific?
Flying over the Pacific Ocean is avoided by most airlines for most flights because it usually doesn’t make sense to fly over it when shorter and safer routes exist. The Pacific Ocean is also more remote and less safe than the Indian and Atlantic Oceans to fly over, resulting in a higher chance of a plane crashing.
