Another 600 Ryanair flights have been cancelled next week due to ongoing strikes.

The budget airline has said it has been forced to cancel 300 flights each day on July 25 and July 26.

Flights to and from Belgium, Portugal, and Spain are affected.

Close to 50,000 customers are set to be affected by the strike which has affected 12 percent of the airlines routes.

Ryanair say it "deeply regret" pulling the flights and say that customers have been offered re-accommodation on alternative flights over the seven days prior to Wednesday and Thursday.

They are also being offered full refunds if they choose not to take different routes.

Ryanair's Kenny Jacobs said: "Ryanair sincerely apologises to our customers for these disruptions which we have done our utmost to avoid.

"Given that Ryanair cabin crew enjoy great pay-up to EUR40,000 p.a. (in countries with high youth unemployment) - industry leading rosters (14 days off each month), great sales commissions, uniform allowances and sick pay, these strikes are entirely unjustified and will achieve nothing other than to disrupt family holidays, and benefit competitor airlines in Belgium, Portugal and Spain.

"All affected customers have been contacted by email and SMS text message earlier today and we will re-accommodate or refund all of those whose flights have been disrupted."
