Again, this is more for me than anyone else, but the following is useful information in terms of planning ahead for flights in to, and out of the UK.
The Eyjafjallajoekull volcano started to erupt on 20 March 2010. Volcanic activity can last anywhere from days to years but 48% of all volcanoes last between 1 week and 6 months. Wind direction needs to change for a period of several days away from the north westerly direction in order to clear an ash cloud. There’s no sign of several days of wind change for the UK in the foreseeable future.
Moral? Don’t book flights in to or out of the UK this side of September.
