If that is the case, and 50 seat aircraft are here to stay, what is going to replace the high cycle CRJ200's and E145's?
Is it full cycle and back to props with ATR's or will it be derated larger aircraft like to CRJ700 and MRJ70.
I don't think there are any expectations that aircraft the size of the A220 would ever be considered within the scope at mainline, but if the next generation of RJ's are heavier because of engine technology while remaining 50/76 seats what is actually being given up?
