Following discussions with airlines, regulators, and aircraft and engine manufacturers the Civil Aviation Authority and the Irish Aviation Authority have introduced new measures to reduce airspace closures caused by volcanic ash.
This means that areas of UK airspace that would have previously been closed can safely open, further minimising flight disruption.
As a result of this change, there are no predicted restrictions on UK airspace in the immediate future. All Irish airports remain open until further notice.
