As previously mentioned, CityJet does some operation on some routes down south in Norway for SAS.
However......
I actually fly the CRJ domestic in Norway irl, however the -200 version which is a little bit more old school and less automatic. Flying the mail for an express cargo operator from north to south and also all the fresh food, dairy products, fruits, flowers etc. up the the remote Top Of The World, Svalbard, Longyearbyen. But you could always simulate that in a CRJ700 I guess. Very challenging to fly into both Tromsö, Bodö and Svalbard with stormy winds, extreme winter condit
