HELSINKI — Some 170,000 passengers had their travel hopes dashed over the weekend as a result of the pilots ****** at Scandinavian Airlines, with no end in sight.

Nearly 600 flights have been cancelled and thousands of passengers have been ******** and the ****** is now in its fourth day.

The flag carrier of Denmark, Norway and Sweden announced further flight cancellations on April 28 as the parties failed to resume talks on a new collective bargaining agreement. It cancelled another 1,213 flights today and tomorrow, hitting some 110,000 passengers.

The open-ended ****** started Friday following the collapse of pay negotiations with the SAS Pilot Group, which represents 95% of the company’s pilots in the three countries.

SAS said it “deeply regrets” the distress to clients on its domestic, European and long-haul flights.
