I agree with u Finnwings, many swedes is going via
HEL to Asian destinations, it's cheaper better and easier and u r also going in the right way, instead of connecting via
CPH (Stockholm is closer to Asia). I dont think there is demand for
ARN-
NRT in todays situation, maybe if SAS splitted up their
CPH-
NRT service to 4x times a week and then fly 3x a week from Arlanda. It's not impossible that SAS will retake
ARN-Tokyo in a couple of years but I think
ARN-
PEK is a more important route for SAS than Tokyo is, because Air China is already flying this route very sucessfull.
