I'm back from the short trip to the West Coast (mostly for millage run purpose). I've originally booked SAS Plus and would like to report that I've managed to upgrade both long haul flights:
SAS Plus -> SAS Business
CPH-SFO 2/9, min. bid EUR 270. I've bet EUR 271 -> won and received 1875 points for that
SFO-CPH 2/12 min. bid EUR 720 / 29000 EB points. I've bet 29001 points -> won
