Thousands of Ryanair passengers will be forced to make alternative travel plans today as cabin crew in Italy, Spain, Portugal and Belgium stage a 24-hour strike.

However there will be no disruption to flights into or out of Ireland West Airport Knock.

Any passengers affected by cancellations have been informed by text or email and passengers not contacted by Ryanair should check-in as usual for their flight.

It comes as IALPA pilots at Ryanair have announced a fourth one-day strike for Friday 3 August.

It's part of an ongoing row with management over seniority, base transfers and annual leave.

Yesterday the airline confirmed that up to 300 pilots and cabin crew could lose their jobs in October as it scales back its fleet in Dublin.
