NATS is advising that the restrictions on UK controlled airspace will remain in place until 07:00 tomorrow, 20 April 2010.

However, based on current ash levels, and no further ‘significant ash emissions’, NATS is predicting that from 07:00 20 April, Scottish airspace and South to a line between Teesside and Blackpool will reopen.

A further announcement is expected at 21:00 today.
