Well, if you would have asked me two days ago, i would have said i would never operate them again, however i would say now they are pretty good.
I am being more picky though. I had previously had 3, one -300 and two -320's. With NEA v2 im only using -300's as they are cheaper to lease and i dont need the extra range of the -320. Im also not sending them on flights above 350nm's. They are slower than i would like, but are faster than the dash 8's. I think once i have the money, im going to replace them with Saab 2000's though until i get saabs, i will take some atr 72's and see how they do.
overall, if you are a new airline, they need to be put on routes with no other airlines running on it. NEAv1 was all routes into already served cities and it took me a game year to make a profit. with V2 im only flying into cities not served and i was in the green within 2 game days. If you are a very well established airline (CI 40+) then they can probably go on any route easily. by using only -300's i will also save approx 80k per plane per month.
