Oh yes, just for info... About my testings:
I am running a regional operation from Venezia, using 8x EMB120 fleet. Practically no competition on any of the routes (except for 1 or 2). Avf LF is 78% (all Y) with default prices about. Route images are nearing 100, and company image is 20.
Transporting about 10-13000 pax / week. And the company profit is between 150k - 290k / week. Aircraft utilization is extremely high (#3 overall in the world, 16.3h/day). Main expense is the staff (ticket sells 1.6m/week, staff cost 0.45m/week).
The start for the regional ops was very hard, I nearly bankcrupted. But now it's getting easier and cannot see it being hard anymore, and actually now the profit margins are closer to what they should be for all airlines actually..
So instead of making regionals easier, I'll have to make the other types harder. But of course still a small adjustment of the staff levels etc. is needed. Of course in this case the fact of no competition and being able to keep the prices is a life saver...http://www.airwaysim.com/game/Info/Others/Airline223
