quick UT question

After adding the Flight one 421C and some repaint to my fleet I added them to UT repaints of Cape Air, Nantucket Airlines and Island Airlines which all have routes in UT. But dont see the planes. Does this mean that i also have to add the flightplans for these airlines? The schedules are there in the status board and the routes show on the map but dont know why I can see the airlines. I have the unpainted airlines of UT enabled. If I do have to add the flightplans which is available how do I go about it since I only want to use certain paint schemes once which I set already in UT?Many thanks for any help.NP
