All flights in and out of the UK cancelled due to Icelandic volcanic ash in UK airspace

From http://www.nats.co.uk/

Statement on Icelandic volcanic eruption: Thurs April 15, 14:00

The cloud of volcanic ash is now spread across the UK and continuing to travel south. In line with international civil aviation policy, no flights other than agreed emergencies are currently permitted in UK controlled airspace. Following a review of the latest Met Office information, NATS advises that these restrictions will remain in place in UK controlled airspace until 0600 tomorrow, Friday 16 April, at the earliest. We will review further Met Office information and at 2000 today (local) we will advise the arrangements that will be in place through to 1200 tomorrow.

We continue to work closely with airports, airlines, and the rest of Europe to understand and mitigate the implications of the volcanic eruption.
