Ryanair has delivered a stark warning to passengers planning to travel in October that hundreds of flights could be cancelled.
The budget carrier is alerting customers about looming strikes in France that threaten to wreck the holiday plans of tens of thousands of travellers. France's biggest air traffic controllers' union, Syndicat Majoritaire des Contrôleurs Aériens, is preparing to down tools from October 7 to 10. The union members are taking action over their current working conditions.
Initially planned for September 17-18, the industrial action was delayed due to political turmoil across the country. Now rearranged for October 7 to 10, one travel company is forecasting 'chaos'. The walkout won't just hit flights bound for France but also those travelling through French airspace.
Now Ryanair's chief executive has warned that 100,000 passengers could see their flights disrupted next week as a consequence of the strike. Michael O'Leary estimated that the industrial action would cost Ryanair around £20m.

The budget airline CEO called for overflights to be protected from strike action, saying disrupting them is an abuse of the free single market. Countries including Spain and Greece already do that, but France doesn't offer such protections.
Mr O'Leary said that Ryanair was expecting to be asked to cancel about 600 flights, with almost all of them overflights. "That's about 100,000 passengers who will have their flights cancelled needlessly next Wednesday and Thursday," he told Sky News.
"On any given day at the moment, we operate about 3,500 flights and about 900 of those flights cross over French airspace and about two-thirds of those, around 600 flights, are cancelled every day there's an air traffic control strike. The UK is the country whose flights get cancelled most because of the geographic proximity to France."
The airline voiced its exasperation earlier this summer when a Belgrade ATC strike held up 99 flights and affected more than 17,800 passengers in merely two days. The French strikes could cause significant disruption.
During the peak travel season in October, Charles de Gaulle Airport alone typically sees over 200,000 passengers daily, and France recorded roughly 1m overnight stays by international tourists between October 9-11 in 2024.
Holidaymakers are being urged to check with their airlines 48 hours before departure to learn of any disruption. They are also advised to brace themselves for a longer-than-expected wait at the airport and arrive well ahead of their flight.
Downloading airline apps can also help you stay updated, and be prepared for delays on things like trains and coaches as affected passengers seek alternative means of transport.
If your flight has been delayed or cancelled as a result of strike action by cabin crew or pilots, then you are entitled to compensation by law. That’s because the airline could have foreseen and preempted this problem.
However, strikes by airport staff and air traffic controllers are not considered to be within the control of the airline, so no compensation would apply. If strikes have an impact on your airport then get their early or follow the advice from your airline. Problems with airport staff strikes can result in major queues to check in bags, so if this kind of industrial action is announced, you might want to think about reducing your baggage to just carry-on cabin bags in order to cut out one queue.
