Longyearbyen ???? Since when does WIF fly to Longyear?
And:
The majority (if not all) of the Q400 destinations in Norway were airfields which has daily 737 services with other airlines!
Sorry, that was meant to be Hammerfest. True about the smaller places being served with the smaller DH8's, but again what WF base their ops on is having a reasonably uniform fleet perfectly suited to serve virtually any Norwegian airport, hence the competitive edge. Mixing in the CRJs would give them hard times no doubt about it.
