24 flights operated by Ryanair between Ireland and the UK have been cancelled this Friday.
It's due to a second day of strike action by Dublin-based pilots in a row over working conditions.
The first strike took place last Thursday, with unions announcing 2 further days of action for this Friday as well as Tuesday July 24th.
In a statement, Ryanair says the strike is unnecessary, adding that the "Forsa Union and the pilots committee don't even understand that their demands will damage Irish pilots prospects."
The airline says anyone on affected flights has been contacted about the cancellations, either by text or by email.
