Awesome idea, but as you say, seems more like a sort of "last mile delivery vehicle" than cargo transport.

You could imagine some sort of futuristic flying Amazon warehouse/drone carrier: It would be pre-stocked at a distribution center, with packets already arranged in a way that they can be picked up by drones individually. Then it floats over a neighborhood while the drones deliver the individual packets to the homes below.

I was thinking of these as an alternative to having a distribution center. They're just always traveling on a few routes determined mostly by prevailing winds, making big circles around the planet. If you live on one of those routes, you can last mile delivery directly from the warehouse as it passes overhead. If not, the drones are loading/unloading a train or some such.
