Yes, I get nervous travelling anywhere, as I get travel sick very easily.
But, if 당신 are referring to the recent problems with plane travel - there is now that added nervousness for me. Although, I myself do not travel abroad, many of my relatives and 프렌즈 do. I fear that something might happen to the people I love.
I know that they say that air travel is still the safest - but, when it is yourself 또는 someone 당신 사랑 - I still worry.
I really only traveled abroad once. It was a little scary but at the same time fun :) I think it's normal to be nervous about this kind of thing, but soon enough your nerves will settle :)
