Thousands of holidaymakers are set to see their plans disrupted amid a number of Ryanair strikes this summer.
The action could cause significant impacts on passengers as flights may be forced to cancel. Staff in Spain are set to walk out on June 24, 25, 26 and 30 and on July 1 and 2, amid discontent about working conditions and pay, USO union said.
Last week labour organisations including SITCPLA and USO came together to demand an uplift, claiming they have "no other option" but to walk out if it is not given.

Similarly, Ryanair's Portuguese cabin crew have said a tree day strike will go ahead on June 24, 25 and 26. The strike could see a possible 50 flights to and from Ireland to Portugal impacted over the course of the three days, the Irish Mirror reports.
Workers are demanding compliance with Portuguese law and better working conditions, Portugal's union of civil aviation personnel SNPVAC said in a statement on Tuesday. The union added: "This mobilisation is not only an opportunity to put the spotlight on multiple attacks on workers' dignity and to make this reality known but also a moment to show unity and solidarity against dumping."
Ryanair's Italian cabin crew has become the latest to announce strikes after unions representing staff in Italy called for a 24-hour strike on June 25. Unions FILT-CGIL and UIL Trasporti said they sought improved pay and conditions after staging a four-hour stoppage earlier in June.
While UK Ryanair staff have not announced a strike, the industrial action could impact Brits flying to Spanish, Italian and Portuguese destinations this summer.
