Wife and I are flying TATL tomorrow with a WF feeder flight from NO to CPH. A pretty normal itinerary for us. Tried to do online check-in and got the following message:
For the first time we got a confirmed advance upgrade from M to Y with points, and the TATL flight has had no/very limited (ie. expensive booking classes only) availibility for the past couple of weeks. Everything looks legitimate when I check the booking via sk website, checkmytrip, etc. We have assigned seats and everything

Any ideas why we can't OLCI?
