Irish airspace has the all-clear from volcanic ash for the next 48 hours, aviation chiefs said on Wednesday afternoon.
Airlines have been given the go-ahead to operate in and out of Ireland's main airports after assessments of the cloud moving out of Iceland.
But the Irish Aviation Authority (IAA) warned a small number of European destinations may be affected and services in and out of the country could suffer as a result.
The authority said it will continue to monitor the situation with the Volcanic Ash Advisory Centre in London, Met Eireann and the Department of Transport.
Airlines, airports and European air traffic service providers are also being consulted.
The IAA said that based on weather patterns it expects Irish airspace to remain free from ash for the coming days.
