The turbulence at Air France looks set to continue into the summer.
After 15 days of industrial action since February, unions representing the airline's workers have announced four more for the month of June.
The new strike days are set to take place on Saturday June 23rd, Sunday June 24th, Monday June 25th and Tuesday June 26th in the next stage of the unions attempt to secure a 5.1 percent wage increase for employees at the airline.
And the number of strike days could increase, according to the unions, which announced the new strike days on Friday.
Unions have criticised the new leadership at Air France for not responding to the fact that the pay deal was rejected by employees at the airline on May 4th.
Air France has just brought in an interim president Anne-Marie Couderc, who will fill the role until September when the role will be filled permanently after the airline's previous boss Jean-Marc Janaillac announced his resignation after the deal was turned down.
In a consultation with Air France employees, 55 percent of staff rejected the wage deal proposed by the company's management.
