In Sweden, pilots employed by SAS walked off the job after negotiations over job security and wages were not settled. It is estimated that as many as 400 unionized pilots went on strike. The strike has already led to the cancellation of 40 flights leaving the Stockholm airport. The pilots are demanding a 3.5% pay increase as well as better pay for new hires that is more comparable to pilots who have been with the airline for a while.
