Lufthansa and SAS will terminate their co-operation on routes between Scandinavia and Germany in June, as the former airline transfers much of its European traffic to low-cost subsidiary Germanwings.
The two legacy carriers formed a joint venture to partner on routes between Scandinavia and Germany in 1995. But SAS says that the "model in its current form is no longer fully compatible with the commercial interests" of both airlines.
Lufthansa is transferring all European traffic outside its main hubs in Frankfurt and Munich to Cologne-based Germanwings, effective 1 July.
The carriers have thus decided to end the partnership on 1 June.
Ending the joint venture will not affect the two airlines' co-operation - including route code-sharing - within Star Alliance, says SAS.
