French cabin crew at Ryanair are calling for strike action, which could lead to dozens of flights being cancelled.
As reported by the Local, staff have filed a notice for 'unlimited' strike action over the summer due to an ongoing dispute about pay.
Members of the SNPNC-FO union had already walked out earlier this week, demanding better pay and working conditions.
More than 40 flights had to be cancelled on Sunday and Monday due to the industrial action.

"As things stand, further walkouts are possible if the company does not meet our demands for a worthy salary and working conditions", said Damien Mourgues from the SNPNC-FO union at the time.
The latest strike noticed, filed by the same union, represents the majority of flight attendants and concerns Ryanair staff at Toulouse, Marseille and Paris Beauvais airports.
They plan to target peak travel times.
Flights to Morocco, Italy, Spain, Portugal, Greece, Corsica, England, Scotland and Ireland are likely to be affected.
The pledge for further industrial action comes in addition to a strike planned at Paris’ Charles de Gaulle and Orly airports on July 1.
Both the Ryanair staff and the Paris airports staff are calling for pay increases to help them deal with the increasing cost of living.
The strike notice is the latest piece of industrial action planned this summer.
Ryanair cabin crews in Spain have announced six days of strikes in June and July over pay and working conditions.
Some 1000 SAS pilots in Denmark, Norway and Sweden could go on strike from late June over disagreements on wages.
The industrial action comes against a backdrop of unprecedented pressure on the industry following a strong return to demand as pandemic restrictions have eased.
A BA pilot told the Mirror how morale at the company had never been lower and that staff were under unprecedented pressure.
Ryanair has been contacted for comment.
