It was cancelled (both legs!!) three weeks before, I was automatically assigned an economy ticket via Madrid and ended up taking a refund and flying with another airline as level/Iberia were very hard to deal with.
BUT leaving you with some hope here - after geeking out on this matter I managed to find that some flights are indeed operated on a chartered Wamos Air Ai EC-NUI that has a 1-2-1 business class.

Good luck!
