Why London-Los Angeles Flights Curve Over Greenland Instead Of Flying Straight West

Airline routes, particularly those spanning vast distances like London to Los Angeles, are meticulously planned considering numerous factors beyond simply distance. The curved path taken by these flights over Greenland is primarily dictated by air traffic control directives and airspace restrictions rather than aerodynamic considerations. Specifically, airlines must adhere to designated airways established by NATS (Nats), the United Kingdom’s Air Traffic Control organization, which dictate specific routes for safety and efficiency. These airways often necessitate deviations from a straight westward trajectory due to controlled airspace requirements in Europe and North America. Consequently, aircraft utilizing this route follow pre-determined paths that frequently involve significant curves above Greenland to comply with these regulations, ensuring safe and orderly flow of air traffic across continents.
