No it is not - if people systematically avoid SAS for their flying business simply because it can not meet their IC travel they will loose money in more verticals than just a single IC route. There has been an outcry for over a decade for more IC from ARN. Especially for frequent travelers who can not rely exclusively on SK to begin with, even for European travel. Now DY has proven that there is plenty of room for additional IC (and EK + QR for that matter) and thereby killing SK's argument that there wouldn't be, it's time to act. Same goes for OSL, QR even has 2 flights a day from there.

ARN-SFO and ARN-HKG would make a lot of sense. The CPH crowd can transfer in ARN instead of the other way around (and not add 3+ hours of travel) for an Asian destination. It would open up the necessary extra capacity to SFO with better connection times.
