That being said, given that they're shutting down OK Plus I think it's safe to assume they will be leaving SkyTeam as well, though as far as I'm aware, it's not officially confirmed yet.

Also, the codeshares with Air Europa and some other SkyTeam airlines are still being sold so who knows what happens there.
