Hi,

have been flying LHR-SVO-KRR several times last year and must say, that the international flights are always cattle calls (cutting the queue mostly works, but somehow it feels awkward).
The national flights of SU are usual scary, but Elite Plus treatment is nevertheless excellent. In KRR the lounge is small, but you are being picked up personally and driven in a small "VIP" labeled van in front of the waiting crowd in the bus which has to wait for the doors being opened until the cabin crew saw you seated (must admit, I loved it ;-) )
The national terminal also does priority seating - but only for queing and going into the bus.
