I use FSC9, with RouteFinder (free) to get the route with the Jetways provided, then I create the route in the CDU/FMC and add a SID, STAR and ARRIVAL RWY. I do not usually make them with the FS Flight Planner, although I have sometimes saved the FSC9 flight plan as a PLN (in the Documents/Flight Simulator X files folder) and then loaded it into the CDU/FMC, then add the SID, STAR and ARRIVAL RWY to that route and it works fine.

I desperately want to know where those waypoints that I couldn't find in the FS Flight Planner, or FSC9, came from. I'm very curious for the answer to that question. HINT HINT :D ;D ;)
