EasyJet staff are planning more strikes over July over work conditions and pay following an early stint of industrial action this weekend.
Spanish workers with the budget airline left their positions between July 1 and July 3 after negotiations with the company failed.
Members of the Spain USO Union are taking action over pay and working conditions with over 450 cabin crew members called to strike.
More industrial action is planned for 15, 16, 17, 29, 30 and 31 July.
USO said: “Spain’s cabin crew has the lowest basic income of all European easyJet hubs.

“If you fly a lot of hours, you end up paying your invoices but reducing your break time and doing a higher number of flight hours.”
While members of easyJet staff in the UK have not announced a strike, industrial action by their Spanish counterparts will have an impact on Brits travelling to certain key holiday destinations.
Strike action is likely to affect easyJet bases in Spain which are Barcelona, Malaga and Palma.
An easyJet spokesperson said the airline plans to operate its full schedule and would do everything possible to minimise disruption.
According to aviation news network FL360aero, nine easyJet flights were cancelled and more than 590 delayed due to the strikes this weekend.
On July 1 alone, four flights were cancelled, with journeys from London and Birmingham affected.
Looking forward to future strike dates, services from UK airports to Barcelona, Malaga and Palma may well be delayed or cancelled.
The budget airline has been hit with chaos over the last few months with numerous delays and cancellations, in no small part due to issues with staffing.
EasyJet’s chief operating officer, Peter Bellew, resigned yesterday following a tumultuous period.
Chief executive Johan Lundgren said: “I would like to thank Peter for his hard work and wish him well.
“Everyone at easyJet remains absolutely focused on delivering a safe and reliable operation this summer.”
The airline has struggled with staff shortages in the UK and had issues recruiting employees for the summer peak period.
British Airways, TUI and Wizz Air have also had issues and cancelled flights ahead of summer.
BA workers at Heathrow are set to strike in July after voting for action over an ongoing pay dispute.
The dates of the planned strike are yet to be determined but it is likely to be during the school summer holidays.
Ryanair workers in Spain are also taking strike action this summer with 12 additional days announced yesterday.
Employees are striking over working conditions with Ryanair bases including Barcelona and Malaga likely to be affected.
Ryanair CEO, Michael O’Leary, has said he expects flight prices to rise over the next five years.
He said flying had become too cheap and it would not be sustainable at the current low prices, and also blamed Brexit for some of the current chaos, calling it a "disaster".
