Not so sure the new SAS lounge will be in the F pier... the corner Pontus/Amex used is not really suited to be a lounge space? Also SAS gave up its domestic lounge in the former T4 (now the C pier) above gate 37. If Swedavia and SAS would collude and try to marginilize LHG (which seems to be the second largest user of ARN) they could move all *A riff raff to C&D. Right now they are maintaining C as the LoCo gates, and EW flies from there. LX is spread over C/E/F, LH in D/E/F, OS in E. D should have some lounge space available above the departure area, that space was previously used for transit security. If they move all international 'unclean' arriving flight to F the space is available for other uses.
