Ah, yes Aeroflot... silly me... and being in Russia and whatnot
If you count the piddly stuff I'd say almost for sure, the main core however must have been the IL-62's, TU-134, TU-154, the latter two flying until pretty recently in fact. Once you add all the foreign stuff they have tried (plenty) and other types (Yaks, IL-86 etc), then surely yes, must be the winner around the turn of the century when the fleet probably was at maximum types.
