In expanding to new airports, its obvious that one would start with 0 RI and low LF. While the LF depends on multiple factors (demand being key, but also time of the day and aircraft) is it a good idea to start marketing a route that you haven't launched yet? I typically route and schedule service a few weeks out before my aircraft get delivered. Just wondering if it would help at all in starting the campaign a few weeks before the first flight or if its just a waste of money and should launch after the route begins to fly. Thanks in advanced!
