Vast Knowledge Indeed !!!
Nope, never claim to have vast knowledge. Although what I do know is that the B732 initial outlay is not much. The operating costs, spares and fuel and is huge and has no long term benefit for a new start up airline to grow. Me - the RJ100 on the cheaper side but then preferred a EMB170/190 if you really want a solid base.....but this is expensive.
Again, just my 10 cents worth.
