Ryanair is expecting over 100,000 passengers to have their flights either delayed or cancelled with French air strikes this week.
Flights heading across Europe are being impacted by the strike action, even journeys that aren't heading to or from France, but simply passing over.
The airline has called on the UK, Irish, Italian and Spanish Governments to take action to protect their citizens and overflights to and from their countries which would prevent thousands of people's flights being cancelled.
