Since I screwed up my plan for a big Soviet fleet, I have since been toying around in Dayton, Ohio most recently with the never used L-410. I actually launched every single model back in JA6 and maintained a fleet of around 40 for a long time but those were subsidized by 20 An-26s and a rather large fleet of DC-9s. They seemed profitable and I had two bases just for them but I never bothered to look at the numbers.
Here I have had a fleet of two owned L-410As and five leased UVPs, although I ran out of cash before I could schedule two of them. Anyway, RIs aren't maxed out yet but I have two aircraft with over 80% LF. One is owned and one is leased with both making $40-$50,000/wk. The other three are half full at this point drawing $20-$30k/wk. Generally, they all fly from 5:00-23:00.
In my best month I managed $1,515,566 in gross revenue but this was immediately gobbled up by nearly a million in staff costs. It hasn't quite been six months yet but I don't think I will learn much more and I am out of money so I am going to take this operation to the third world shortly aiming to own every plane. The difficulty is in finding a place with enough <300NM routes.
