With a lot of the higher end drones, you can do autonomous flying via GPS. Just tell the drone a point on the map to go to and off it goes. You could easily have a partner in crime just waiting at the pre-determined GPS coordinates to pick up the drone and the cargo. The partner could then swap the battery pack and send the drone right back to you.
This can be accomplished right now, with pretty much any of the off-the-shelf, high-end consumer drones.
Setting up a fixed wing drone requires a lot more work. You would have to set up a parachute with the payload and some sort of release system, plus it would have to have enough battery to fly back. The receiving party on the other end wouldn't be able to send anything back with the drone, either, because it would never land. If you wanted it to land, then you have to deal with all sorts of other variables.
Drones that can take off and land vertically are far more flexible for point to point deliveries than fixed wing drones.
