 Interestingly, the vast majority of them are in the US. We've known that the big US airlines grounded their flights for a while, but of the 1,400 flights reported cancelled around the world, over 500 of them are in the US, where it's been night time and people are just beginning to start waking up. Whether that's because they're counted as being American flights, even if they're between two different destinations that aren't in the US but are on American carrier, I'm not sure.
