For the Concorde Room, yes if you leave via AA you leave via T3 and so no Concorde Room, but you do get Galleries First which isn't bad. Back to Norway, yes it is merely sufficient to arrive by BA First and then depart the same day on a BA flight from T5 anywhere, it's not the "major part" thing, if you did First from Moscow then economy to Buenos Aires (God help you) then you'd still get Concorde.

If you can sleep in SAS Business then Club World alone would work very well for you, everything else would be a bonus.
