Apparently CO had so many issues with coach-flying SkyTeam ElitePlus members getting into or trying to get into the Stockholm (ARN) Novia Lounge that Continental's given the lounge operator a laminated sign indicating that entry is ONLY for CO BF passengers. Amusingly the sign is right on the front desk, nearly full time as of late.
I heard a bunch of Scandinavian ElitePlus say things akin to "yet another reason not to fly CO out of here". Apparently I'm not alone in minimizing my use of CO when it comes to departures from the Scandinavian market -- significantly related to CO's cheapskate lounge cut-off. [Note: CO limits lounge access there to CO BF passengers yet every other SkyTeam airline I've flown out of there -- and that they've flown too -- provides departing SkyTeam ElitePlus members in coach lounge access to those contracted lounges too.]
