Sovietjet,
I recall reading once that at its peak, the Aeroflot fleet comprised 12,000 aircraft. Not sure at which point in its history that peak occurred, or how many aircraft it had before it was broken up into 400 different sub-airlines, but I believe that's a reliable figure. It may be somewhat misleading, though, as I believe the Aeroflot fleet included every civil aircraft in operation in the US
SR, including planes like cropdusters. Someone please correct me if I'm wrong on this, though.
I couldn't even begin to speculate how a fleet that size was managed, but I would speculate it was managed about as well as the US
SR managed just about everything else.
Syncmaster,
I'm having trouble finding the numbers for DL at the moment, but I believe it has almost as many mainline aircraft as UA (~550), and carries significantly more passengers. There's quite a gap between those two airlines and AA, however, when counting by mainline aircraft only.
