I think there was a bit of overreaction, and not nearly all the areas that closed their airspace should have done so... though I am glad I am not travelling anywhere. It's not like you can get from Europe to US in any way other than flying nowadays. Though the upside is I have enough people in Continental Europe I could beg for a place to stay in an emergency like this, the only issue would be getting from where I am to where they are... could be difficult but doable. Normally I opt for taking any option as long as it is going in the right direction... And other areas are still flying to the US, so it wouldn't be so bad for me personally. But I sure do feel for people who are stuck. Hopefully, by the end of the week the situation will be more or less resolved.
