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 cabin crew in a number of other European countries have voted to hold one and two-day strikes later this month.
