Most commercial flights often travel over the Arctic region, but very few planes fly across Antarctica. Many people think Antarctica is a restricted no-fly zone, but that is not true.
Commercial airlines are allowed to fly over Antarctica. However, factors like geography, safety risks, extreme weather, and high costs make it one of the least preferred flight routes in the world.
Are commercial flights banned over Antarctica
There is no international rule stopping commercial planes from flying over Antarctica. In fact, some special sightseeing flights and scientific missions regularly travel above the continent.
Aircraft usually follow great circle routes, which are the shortest paths between two places on Earth. Since major cities like New York City, London and Tokyo are in the Northern Hemisphere, many international flights naturally pass near the Arctic region.

Southern Hemisphere routes work differently
As per NDTV reports, the situation is different in the Southern Hemisphere. Cities like Sydney, Johannesburg, Santiago and Auckland are located differently on the globe.
Even the shortest flight routes between these cities usually do not require planes to fly across Antarctica. Airlines find it more practical and fuel-efficient to fly over the Southern Ocean instead.

Low demand also affects flight routes
One of the main reasons commercial flights avoid Antarctica is the lack of demand. Most of the world’s population, businesses, and busiest airports are located in the Northern Hemisphere, which creates heavy air traffic near the Arctic region.
Antarctica has no cities, permanent commercial population or major travel demand. Because of this, airlines have very little reason to create regular flight routes across the continent.
Extreme weather creates major risks
As per NDTV reports, modern aviation follows strict safety rules called ETOPS, which require planes to stay within a certain distance of emergency landing airports. While Arctic flight routes have nearby airports, Antarctica has almost no proper emergency landing facilities.
The continent also faces extremely harsh weather conditions. Temperatures can drop below minus 60 degrees Celsius, while strong winds, snowstorms and whiteouts make flying very difficult. During winter, Antarctica experiences months of near-total darkness, which increases risks during emergencies.

Special flights still operate occasionally
Although regular commercial flights rarely cross Antarctica, the continent is not completely isolated from air travel. Some airlines, including Qantas, operate sightseeing flights over Antarctica without landing.
Research teams and government agencies also use specially designed aircraft for scientific missions in the region. Some international flights travelling between South America and Australia may also pass close to Antarctic airspace.
Commercial airlines avoid Antarctica mainly because regular routes across the continent are impractical, expensive and risky. For most airlines, safer and more efficient alternatives already exist.
