Creating your own AI is an extremely tedious and pointless operation. I don't understand why people waste time, when there are several sources out there, FREE i might add that give you half decent AI with a click of a button.
For your information however there is two ways. Edit the code yourself, making new lines for additional routes or use a program such as yroute to edit your flight plan.
