We regret to inform you that due to the 47th French ATC strike, we have been forced to cancel a number of flights: https://t.co/WPS9U3HQiC— Ryanair (@Ryanair) May 26, 2016
Ryanair's Kenny Jacobs told Newstalk Breakfast that the strikes have cost airlines billions over the years.
He said two things can fix the problem for passengers - a binding arbitration process to prevent strikes, or allowing other ATC's to run French airspace.
He also called on people to support Ryanair's petition to 'Keep Europe's Skies Open'.
Once it reaches one million signatures Jacobs said Brussels will be forced to "consider legislation to prevent further strikes".
More strikes are planned for next week on June 3rd, 4th and 5th, with June 14th - the day after the Euro 2016 match between Ireland and Sweden - also penciled in.
Kenny Jacobs said it is "very cynical timing by the French" as they are "targeting specific games" to cause maximum disruption.
