Paris, Dhu-AlQa'dah 18, 1435, Sep 13, 2014, SPA -- Air France has warned that about half of all its flights scheduled for Monday could be cancelled because of a pilots' strike, chief executive Frederic Gagey told French radio. The airline could lose between 10-15 million euros because of the strike, Gagey said Saturday, according to dpa. The SNPL union representing Air France pilots called the week-long strike to pressure Air France to give pilots at its low-cost subsidiary, Transavia, the same wage conditions as those working for the mother company. Gagey said negotiations with the union would continue through the weekend in efforts to avert the strike action. -- SPA 22:23 LOCAL TIME 19:23 GMT www.spa.gov.sa/w
