Unfortunately your SAS flight will arrive around a half hour after British Airways' nonstop 747 from London, which tends to run very full. If the BA flight is delayed at all, or yours is early (both possible) then the crowd at immigration and customs - which is not a very big station - can be rather large. Nothing you can do about it, but I would not delay getting off the plane or into the lineup for Immigration.

Past that, you should be fine, with adequate time.

Welcome to FT by the way.
