Is it a good idea...

[matty_clark]

     .... to start a route marketing campaign before a new route actually starts? For example:  Im waiting for a delivery of a plane, got my schedules for that plane sorted and start the marketing for the new routes a few days before. Would it maximise the LF from the 1st day?

No.  Route Image remains at 0 until you start flying the route.  You can delay the start of the marketing campaign until after the aircraft is delivered though.
