Between May and July, Amazon added nine planes to its Amazon Air fleet, "the most it has added over a three-month span since its inception," said the report issued Thursday by DePaul University's Chaddick Institute for Metropolitan Development.
"Amazon Air expanded rapidly during summer 2020, a period otherwise marked by sharp year-over-year declines in air-cargo traffic," the report states.
Amazon's air fleet, launched in 2016, is a critical part of its push to provide one- and two-day delivery. The company still relies on outside carriers for a significant share of its deliveries, but it has gradually moved more of its logistics operations in-house, allowing it to better control costs and delivery speeds. Analysts believe Amazon's air fleet, combined with its massive network of airplanes, truck trailers and vans, could one day position it to rival UPS and FedEx.
The coronavirus pandemic has generated even more pressure on Amazon to ensure fast delivery, as it saw a surge in online orders from stuck-at-home shoppers who turned to the company for essential goods and groceries, along with other products like office supplies and electronics.
While its fleet has grown since May, Amazon Air still remains smaller than its rivals, including FedEx, which operates 463 planes, UPS' fleet of 275 planes and DHL's 77 planes, DePaul researchers said in a separate report published in May.
Amazon's $1.5 billion air hub in northern Kentucky could help give it an edge, the report said. The hub, scheduled to open in 2021, is designed to have capacity for 100 Amazon-branded planes and handle an estimated 200 flights per day.
"The massive investment being made in a large hub at Cincinnati/Northern Kentucky International Airport, however, could change everything," the report said. "This hub appears to be the lynchpin to Amazon's efforts to develop a comprehensive array of domestic delivery services across the United States."
