Uh...

Sorry, but I don't think I've understood you perfectly. You want to know how to craft personalized AI traffic, to make said traffic follow your routes and land at your airports?
If it's this you meant, know that it's a not so intuitive process, and you'll have to learn on a trial by fire, on your PC, on your sim, experimenting.
For making a new traffic in FS9, you better begin from the start. Download Ttools, here:
http://www.simviation.com/fs2004utilities1.htm and read its help instructions. The workings of AI traffic is detailed quite clearly there.
If you're serious in wanting to add some traffic of your own, always on the same page download AFCAD 2.21 too. It might be necessary for you to modify the parking slots of an airport, and should this need arise, AFCAD is everything you'll need (shame in fact that, how things are, it's difficult that we'll ever see a newer version)

).
There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
