Well Iberia pilots get 2 "pagas extras" per year and have far more social benefits than Norwegian slaves hired by OSM
Moreover,iberia pilots transfering onto long haul fleet must have a full ATPL licence, so you wont see any cadets at all on the widebody fleet.
Anyway, I understand that Iberia pilots and cabin crew will launch this new airline for 12 months, but then there will be a proper AOC and proper staff and crews.
