I connected through OSL on my way to KRS today on separate tickets and couldn't use the Connecting Norway route.
I arrived from LHR, turned left into flight connections security halfway down the corridor after passport control where my onward boarding pass was inspected, got through and was told to follow the Connecting Norway signs. I scanned the same boarding pass at the automatic gate at the customs channel, and was rejected. A member of staff then came over to tell me that if my connecting flight wasn't on the same ticket as the inbound, I'd have to go landside and start again.
Left me wondering what the point of Connecting Norway is...
