Holiday-goers are facing a summer of potential travel chaos as Ryanair cabin crew will today warn that they could join pilots in strike action, which could ground hundreds of flights.

Ryanair may have created a key moment in its history by officially recognising a pilot union here for collective bargaining purposes as of yesterday, but the airline will still endure a strike today by its pilots in Germany.

Latest: Ryanair have said that pilot unions in Ireland and Germany have agreed to meet them on Wednesday, December 20, to discuss union recognition.
