AMAZON VS UPS AND FEDEX

When it comes to UPS & FedEx, I am not looking at Amazon selling its service to other shippers. I think they first shift more of their own volume to their planes. That’s cargo not available for UPS and FedEx. I builds their Supply Chain Velocity that drives their Order Delivery Velocity which adds to their competitive advantage. Which means less cargo for FedEx & UPS. Eventually they sell their services on the market based on proven velocity. Amazon poses a challenge to logistics outsourcing & commercial transport across modes. IMHO
