I think SAS have a problem with the aircraft type on their intercontinental fleet.
It's all 767s at present and they are just too small. They fly with them full or nearly full on many routes.
The solution was to buy bigger aircraft, hence the purchase of the A330s and A340s. This then gives them the possibilty to use the 767s on other new routes. If the new routes are from CPH/STO/OSL to destinations that are not directly served by another Star carrier to CPH/STO/OSL, I think the other Star carriers would not complain too much.
