Your answer depends on where you want to go in Antarctica. There is no commercial air service to anywhere on the continent. You can fly commercially to New Zealand, Australia, Chile or Argentina -- even South Africa, and from there charter a private flight to your Antarctic destination.
Be aware that you are responsible for all expenses related to your commercial flight, for you, the crew, the equipment and so forth.
