Generating routes

Can anyone recommend a program that will generate flight routes? Something like airliner pilot would do, but i have fs passengers so i don't really wanna buy airliner pilot.
I here this program is good because it generates the routes dependant on aircraft range etc, its a shame fspassengers cannot do this.

I got a really good one online: Route Finder

If this is what you need, http://www.simroutes.com. You can save the routes to your hard drive.

Edit: cheechm beat me

cheers guys, thats exactly the kind of thing i was after nice one.
