Since Vladivostok Air is now part of Aeroflot, are they also part of the Skyteam? I've called Aeroflot recently and was told that Vladivostok Air is not part of Skyteam even though their flights are now coded as SU flights.
I'd like to redeem my DL miles on a a flight operated by them. It's currently marketed and coded as an SU flight but for some unknown reason, DL states those flights are not eligible for redemption.
