Great aircraft, almost an easy mode IMO if utilised correctly. Such low fuel consumption, cruises faster than 737/A320 (+looks nice).
My advice, fill up with high density seating, knock a few minutes off the turn time and restrict its use to routes <600nm and you should make a killing with it.
4 sectors is ideal to make the most money if you can schedule rightly and have freedom of slots. (EDIT: On short <400nm routes you should easily be able to squeeze out 5x daily).
