For an airline your size, I would say no, not until you get quite a bit larger. Also, just a warning, make sure you keep good fleet commonality. Having Embraer 110s and 120s is OK (though they are very similar, so it would be better to choose just one) but don't get any more fleet types until you have 15 planes (keep it at 2 fleet types max until then). Another warning, it is hard, nearly impossible, to run an airline entirely on 17 passenger planes in Airwaysim,which is what you seem to be trying to do. Yet another warning, I have found that 17-20 passenger planes (like your Embraer 110s) have trouble making money on flights more than 200 miles; for your Embraer 120s, keep it at 300 or 400 miles max.
