Ryanair has warned it is to cancel up to 100 flights on Thursday due to another Air Traffic Control strike in France.
The Irish carrier says it has been "forced" to cancel the services to/from Paris Beauvais Airport at short notice.
It says affected passengers have been notified and advised of their options to either move to another flight or to receive a full refund.
Ryanair says there has been 84 days of French ATC strikes since 2023, "forcing airlines to cancel thousands of EU overflights from Germany, Spain, Italy, Ireland and the UK".
However French flights are protected under Minimum Service Laws.
The company is calling on the EU Commission to take "urgent action" to protect overflights and passengers.
A Ryanair spokesperson told Newstalk passengers are 'sick and tired' of the disruption.
"It is inexplicable that [European Commission President] Ursula von der Leyen and the EU Commission have failed to take action to protect EU passengers’ Freedom of Movement during these repeated French ATC strikes," they said.
"As a result, we have been forced to cancel almost 100 flight to/from Paris Beauvais Airport tomorrow, unfairly disrupting thousands of EU passengers’ travel plans at short notice.
"EU passengers are sick and tired of suffering unnecessary cancellations during ATC strikes," they added.
The company says more than 2.1 million people have signed its 'Keep EU Skies Open' petition.
