The pilot strike that crippled Scandinavian carrier SAS for nearly a week ended Thursday night.

SAS came to terms on a new three-year collective bargaining agreement with the unions and employer organizations that separately represent its pilots in Norway, Sweden and Denmark.

Over the course of the six-day strike, SAS canceled 4,015 flights.

SAS said operations will return to normal gradually over the next few days. Traffic disruptions will continue in the meantime. Some U.S. flights resumed Friday, while others were cancelled. For example, an SAS flight from Copenhagen to Newark operated while the carrier's Oslo-Newark service did not.
