Qantas QF14 Flight: Buenos Aires – Darwin

In early October 2021, Qantas flew a one-off repatriation flight from Buenos Aires, Argentina, to Darwin, Australia. It was the southernmost long-haul flight closer to the South Pole than any other passenger flight.

If Earth were flat, the flight should fly over South America, Canada, Russia, Japan, and Indonesia. But it flew over Antarctica instead, because the Earth is a sphere, not flat.
