Oh really?

My timing must be bad because on 2 July I flew Aeroflot, operated by Vladivostok from KJA-KHV-NRT, and could not be awarded my Delta miles, even though the flight was advertised and sold to me as Aeroflot (first time that has happened to me). I wondered if there's another possible mileage program to be awarded these Vladivostok miles besides Aeroflot's own Bonus. I would have signed up to be an Aeroflot Bonus member, had I not originally been earning the bulk of my miles with Delta and wanted to keep it that way. I've now flown almost 25000 miles in the last year with just Aeroflot (if you count the two Vladivostok flights) and am starting to wonder if I shouldn't have just made them my main carrier...

I also can't transfer miles between the SkyTeam programs, I believe, right?
