Arctic polar routes are now common on airlines connecting Asian cities to North American cities. Emirates and Qatar Airways fly nonstop from Dubai and Doha to the US West Coast (San Francisco, Seattle, and Los Angeles), coming within a few degrees of latitude of the North Pole.

In June 2004, Singapore Airlines introduced Flight SQ21, using the Airbus A340-500 on a record breaking 15,344-kilometre (9,534 mi; 8,285 nmi) great circle route from Newark to Singapore, passing within 130 kilometres (81 mi; 70 nmi) of the North Pole.

We fly over the north pole all the time. Take a flight from JFK to Seoul.
We don't fly over the south pole because there are no meaningful passenger routes that would travel that way. If you're departing from, say, Buenos Aires, where do you go that flies over the south pole? Maybe Perth, Australia? Not a high demand route.
But there are no restrictions on airspace or aircraft from flying over either of the poles.
