Congrats on overcoming the discomfort.

To me, it's all related to our mental state, if I think I am going to vomit then I surely will. For that, I always carry earphones while traveling so that I can keep my mind engaged fortunately I have never faced anything like this while traveling as I have always tried to have a positive mindset that these won't affect me.

The view from an airplane, like the one you have added is all we need to get lost, away from these thoughts.
