Less competition to where? Tyler, TX on Tuesdays? Des Moines on Fridays? Less competition in LAX? EWR? F9's biggest competitor seem to be Allegiant. NK and F9 overlap on roughly 500 out of 2800 routes. That's not exactly hiking up the skirt. I don't think there's anyone with anything bigger than a CRJ9 standing in the way of F9's routes. I can't see how NK alone or with B6 could have a significant impact on F9.
