Why Do Planes Fly Over The Arctic But Not The Antarctic?
Commercial flights frequently cross the Arctic but rarely Antarctica due to differences in global travel demand and geography. Flights between major cities in the Northern Hemisphere often use transarctic routes to reduce distance, fuel burn, and operating costs.
Commercial aircraft frequently fly over the Arctic but not Antarctica. The difference lies in global travel demand and geography. Major cities in the Northern Hemisphere are connected by transarctic routes, reducing distance and operating costs. For example, flights between New York John F. Kennedy International Airport (JFK) and Hong Kong International Airport (HKG) use this route. In contrast, major cities in the Southern Hemisphere, such as Sydney and Santiago de Chile, have great circle routes that remain over open ocean rather than Antarctica. The lack of commercial population and passenger demand in Antarctica means there is little incentive for airlines to operate Antarctic crossings. As a result, airlines like Cathay Pacific, All Nippon Airways, and Korean Air operate regular transarctic flights, while Antarctica remains largely avoided.
