Latest NATS update: not so good (2:30 am London)
"The cloud of volcanic ash continues to cover much of the UK and the eruption in Iceland continues. Following a review of the latest Met Office information, NATS advises that restrictions will remain in place in UK controlled airspace until 1900 (UK time) today, Friday 16 April, at the earliest.
However, flights in Northern Ireland and the Western Isles of Scotland to and from Glasgow and Prestwick may be allowed up to 1300 (UK time) today, subject to individual co-ordination. North Atlantic traffic to and from Glasgow, Prestwick and Belfast may also be allowed over the same period. We will review further Met Office information and at 0830 (UK time) we will advise the arrangements that will be in place until 0100 (UK time) on Saturday, 17 April.
In general, the situation cannot be said to be improving with any certainty as the forecast affected area appears to be closing in from east to west. We continue to work closely with airports, airlines, and the rest of Europe to understand and mitigate the implications of the volcanic eruption."
