The Irish Aviation Authority has announced the reopening of their airspace from two o’clock this afternoon (CET).
Flights to the from the country were called off earlier, following more eruptions from the Icelandic volcano.
The IAA say they are reviewing the situation, and that there could be more periodic closures over the summer.
The ash cloud also forced the closure of some airports in Northern Ireland and parts of northern Scotland, including the Hebrides.
Last month, the volcanic cloud wreaked havoc for tens of thousands of passengers and cost airlines millions of euros, as flights were banned across Europe for six days.
Following much criticism, European ministers are meeting in Brussels later today to discuss ways to improve its response to this type of crisis.
