Ryanair has announced it will cancel up to 30 Irish flights this Thursday, during a strike by pilots.
The airline says only some services between Ireland and the UK will be affected, while all Ireland to Europe flights will operate as normal.
Dublin-based pilots are holding a one day stoppage in a row over working conditions.
Ryanair says customers whose flights are affected by the strike will have received a text or email today notifying them of the cancellations.
Customers who have not received a text or email should arrive as scheduled at their departure airport.
