SAS is a tiny airline and they can’t support three long haul hubs to start off with. If a long haul flight is to survive it needs sufficient O&D as well as good feed at least in one end. SAS’ connectivity ex OSL and ARN is terrible unless you have a domestic connection. Moscow, St Petersburg, the Baltics, the UK and northern continental Europe are natural feeder areas for SAS but what sort of connections do they offer for their longhaul flights? Apart from London, there are no flights arriving in time to catch EWR or MIA without staying overnight.
