Long-distance flights often appear to head "out of the way" toward the North Pole because they are following a Great Circle Route, which is the shortest distance between two points on a sphere. Because the Earth is wider at the equator and tapers at the poles, a straight line drawn on a flat map is actually a longer path than a curve that follows the Earth's natural bulge. By flying more northerly latitudes, airlines can save thousands of miles and several hours of flight time on transcontinental journeys, such as those from London to Los Angeles or New York to Hong Kong. Additionally, these routes often allow planes to catch the Jet Stream, powerful high-altitude winds that can provide a significant "tailwind," further increasing fuel efficiency and reducing travel time. While it looks unusual on a 2D screen, it is the most direct 3D path possible.
