Flight restrictions across the majority of the UK remain in place until 1am Saturday, April 17.
Air traffic control service Nats said flights from Northern Ireland and the Western Isles of Scotland to and from Glasgow and Prestwick may be allowed to take off until 7pm today, depending on individual circumstances.
Some north Atlantic flights to and from Glasgow, Prestwick and Belfast may also be permitted during the same period.
Weather forecasts are indicating that the whole of Scotland and Ireland’s airspace may be opened entirely from 7pm although the situation is still being monitored.
For the time being, all other restrictions across the rest of the UK remain in place.
Nats banned all commercial flights across the whole of the country yesterday as a result of the cloud of volcanic ash.
A further statement is expected from Nats at 2.30pm today with further updates.
