Why Don't Planes Fly Over the South Pole?

Airlines fly over the North Pole all the time. I once flew to Hong Kong by going over the Arctic Circle, which looks really weird on a mercator map. But there are no commercial airline flights that go over the South Pole. Half as Interesting explains why.  

Note: this is about commercial airlines flying over the South Pole. Yes, Antarctica has airports, but you can't expect them to have mechanics and parts for your Airbus, much less accommodations for passengers. If you are a scientist at McMurdo and need to go to the South Pole, you will probably be taking a military plane. If you ask me, that's beats a dogsled any day.
