I believe in some rare occasions they still dock directly to some aircraft as part of the normal boarding procedure. You'll see gate numbers (letters actually) that don't correspond with the physical terminals.</font>
I believe that the original airport didn't have the outlying terminals. The idea was that you boarded the lounge at the main terminal (architectural masterpiece that it is) and took the lounge to the plane.
Today SAS can't access its gate (B37) due to construction so you board at B37 onto a lounge. On the return the mobile lounge takes you directly to customs from the plane. It actually makes the arrivals quicker than UA, especially if you are in the front of the plane. On UA you have this long walk to the mobile lounge and then they wait until everyone, including the FAs, get on board. That can easily take 20+ minutes after arrival. (The connecting passengers, I believe, go to a special customs area in terminal C. On SK they have to shuttle back from the main terminal. I suppose that any airline operating out of terminal B has to do that.)
