How long does it take to travel by aeroplane from the UK to Antarctica?

Answer 1

Please be aware that there is no commercial air service to anywhere on the Antarctic continent.

Your choice, then, is to decide where in Antarctica you want to land. Your choice will dictate which commercial route you take from UK, to New Zealand, Australia, Chile, Argentina or even South Africa.

From there, then, you can charter a private expedition to take you to your Antarctic destination. You are responsible for all expenses for yourself, your team, your equipment and so forth, to and from Antarctica.
