Important notice: The IAA (Irish Aviation Authority) may impose no fly zone over Ireland on Tuesday due to volcanic ash moving south from Iceland. Over-flights of Ireland from Britain and Europe are not expected to be impacted, neither are airports in the south of Britain, including London's all airports.

According to IAA, a no fly zone may affect Dublin, Shannon and some regional airports. A decision will be made following a further update from the Volcanic Ash Advice Center at 1900 GMT.
