Guys, you can fly any plane in a profitable way. It always depends on your overall situation: Your competition, your route demands, first class/business class, fuel prices etc. You cannot make a general statement that this plane works and this one does not. There was much talk about whether you can fly props in a profitable way in current ATB2 and yes you can. However, there are many who do not succeed, for different reasons.
I am considering ordering CRJs in ATB2, but I do not want to wait such a long time. Because competition will be very different once these planes will be delivered and who knows how the slot situation will be by then. I think this is just a legitimate thought in the current state of the game.
