Airplane routes argument for flat earth.

I've always thought the airplane routes argument was pretty interesting in supporting the possibility of a flat earth. I have not delved into it deeply on my own but rather have relied on video makers like the following to study. Now, with my Antarctica perimeter distance / time argument, this airline route argument becomes a little more interesting to me. What if I could do something similar for Antarctica as this video does for intercontintental flights? In a similar way, I'm attempting to find out what the travel times, directions and distances are around Antarctica itself or even within Antarctica. Give this particulalry good fast paced and well labelled video a go and then imagine viewing something similar for Antarctica. Maybe I can get the creator of this video to address Antarctica in the same way since I can't make videos like this.
