PARIS (AP) — Despite no deal in sight, Air France’ s main pilots union on Sunday unilaterally ended a 14-day strike that grounded roughly half of the airline’s flights, stranded passengers worldwide, cost tens of millions of dollars and led France’s prime minister to decry a “selfish” walkout.

After a late-night, 15-hour negotiating session with management, leaders of the SNPL pilot union walked away with no accord, but with the realization that the strike “is not an end in itself,” union spokesman Antoine Amar said. In a later statement, the union said it was ending the strike “in the interests of the company and passengers.”
