Ive run into another question. Some SK coded flights are operated by Cityjet. Do they accrue XP? I think I read somewhere that only flights on Skyteam metal accrue XP.
Something of a pain for me as I am always flying from BHX for the first leg which always (almost always?) seems to do BHX-CPH on Cityjet

According to Flying Blue site
https://www.flyingblue.com/en/earn/p...avian-airlines
"Earn Miles and XP on flights marketed as SAS (SK) and operated by one of the SkyTeam airline partners and with a booking class listed in the earning scheme below"

"operated by" seems to be the key here which suggests Ive answered my own question. Suddenly multi hop flights in business (giving premium economy XP) on SAS look much less attractive as a way to grind XP
