It's interesting that Amazon (who spends a fortune on trucking) has created their own cargo airline and starting buying metal because it works out better for them than paying a trucking company. They make money on fast turnaround and big distribution warehouses close to population centers, then they truck the last mile with their own vans. Historically, the cheapest ways to ship anything are by sea, by rail, and by truck, in that order. Airplanes are still inordinately more expensive but folks are willing to pay for that quick delivery that trucks and rail simply can't do.
