Amazon Could Take a 30% Stake in a Large Cargo Airline

As part of the agreement, Atlas Air Worldwide Holdings Inc. will acquire and operate 20 Boeing Co. 767-300 freighters for Amazon, according to a statement from the airline Thursday. The deal mirrors a March transaction with Air Transport Services Group Inc. and would double Amazon´s cargo-hauling fleet to 40 Boeing 767 freighters.The Seattle-based retailer is moving quickly to build up its delivery network, aiming to reduce its dependence on United Parcel Service Inc. and FedEx Corp. as it expands its Prime membership service that delivers some orders in as little as one day. In light of the company´s aggressive moves, the question for some analysts is how much Amazon intends to encroach on the package carriers´ turf.
