To "enjoy this privilege", you simply acquire or build a vehicle that can pilot itself. Some are available in the marketplace, for example, usuall described as "autopiloting", "A.I.", "automated tours", etc, but that would vary by maker. If you are actually serious about implementing this, the rule of thumb is to be respectful of sim resources and limit the numbers of vehicles to a small number, unlike the notorious "scourgemobiles".
My aircraft don't fly around and pick up people and take them back to my land, as you imply. In fact, you're unlikely to ever see them outside of Abbotts. They are temp-on-rez and vanish on their own unless someone boards them when they take off FROM ABBOTTS. As well, they do not advertise in any way, and since you seem to be considering trying that, I would strongly advise against it.
So, to sum up, ANY resident can set up automated flights, but try to be respectful. Don't advertise; don't over-use sim resources. If you set them up, do it as a service to SL, and not for self-promotion, as you seem to want.
