Stockholm is Company HQ.
Main hubs are CPH,ARN and OSL.Operationally,the CPH hub is the main,as it is the intercontinental hub of SAS.
According to SAS policy,new destinations will more often than not be served initially from CPH,then from the 2 other hubs when the traffic increases.
The 3 hubs are more or less equal as regards maintenance.
"Secondary" hubs are Gøteborg (GOT) and Bergen (BGO).Fairly extensive domestic and international network but no crewbases.
