Unions representing the majority of workers at Aer Lingus are to serve notice of a two-hour stoppage on Monday 19 November.
In a statement they said the stoppage would take place between 10am and midday on that day.
In a joint statement this afternoon SIPTU, UNITE the TEEU and IMPACT all said that any disruption to passengers would be solely due to the decision of Aer Lingus to stop talking to staff representatives about their future retirement incomes.
Aer Lingus said the discussions had been overshadowed and hampered by a union interpretation that a proposal targeting pensions worth 85% of final incomes had been agreed with the DAA.
The airline called on the DAA and unions to resume discussions and clarify their positions.
In a statement this afternoon, Minister for Transport Leo Varadkar said: "Strike action is regrettable.
"It will inconvenience thousands of tourists, travellers and business people and will damage the financial position both of Aer Lingus and the airports, which is of no benefit to anyone working in aviation in the long term.
"Strike action should never be inevitable and both sides should start talking again."
