I've flown Saga business class - it was nice! However, be aware when flying Icelandair and aquiring miles on SAS on certain routes. Don't know if they changed, but on the Icelandair site they claimed all flights would earn miles on SAS Eurobonus. Certain routes, however, do not (like from NYC). When I called them on this and inquired and pushed it with SAS, didn't matter. Never got the miles.
