The funny thing is that the main airport here in Iceland is actually open (wind blowing away from it, towards the volcano) but the planes can't take off cos most of them are headed for the UK or North Europe

And please note, this eruption is in a small glacier but the next glacier over is bigger, with a nastier volcano in it. Historically the one erupting now seems to have set the other one off. So who knows what will happen next.
But I am sorry for all the folk who have had their plans disrupted.
