Non direct flight is okay, but keep logical with the route.

If you would like a simple example, you can fly from Sydney to Brisbane via Melbourne.
That is literally going the wrong way.
Yet because of seats on flights, some times that will be a cheaper option.

No, you haven't.
You have explained nothing and instead just provided entirely vague empty claims.
