Question: can you fly directly over the south pole

Answer: No, Few airlines fly between cities having a great circle route over Antarctica. Nonstop flights between South Africa and New Zealand, or between Perth, Australia and certain destinations in South America (including Buenos Aires and São Paulo), would overfly Antarctica, but no airline has scheduled such flights. Flights between Australia and South America and between Australia and South Africa pass near the Antarctic coastline. Depending on the winds, the Qantas flight QF 63 from Sydney to Johannesburg-O.R. Tambo sometimes flies over the Antarctic Circle to latitude 71 degrees as well and allowing views of the icecap. Qantas also flies nonstop between Sydney and Santiago de Chile, the most southerly polar route. Depending on winds, this flight may reach 55 degrees south latitude, but other times 71 degrees, which is enough to cross the polar ice cap. The polar route across the remote southern Pacific Ocean between South America and Oceania was pioneered by Aerolineas Argentinas, which began service between Buenos Aires via Rio Gallegos to Auckland in the 1980s with a Boeing 747-200 aircraft. Aerolineas Argentinas later operated to Sydney, but ended its flights to New Zealand and Australia in 2014.
