during phase two. Amazon eventually plans to have over 100 aircraft based at CVG with over 200 daily flights and 15,000 employees. In July 2020, Amazon Air had secured up to six million gallons of sustainable aviation fuel (SAF) supplied by Shell Aviation and produced by World Energy. In September 2020, Amazon committed to buy four aircraft under their own operations. These are the first aircraft the company will own rather than lease. The four 767-300 aircraft were previously under the ownership of WestJet, who purchased them from Qantas in 2015. In January 2021, with passenger air traffic severely depressed and cargo traffic higher due to the COVID-19 pandemic, Amazon announced it had completed the purchase of 11 Boeing 767-300s from Delta Air Lines and WestJet. In March 2021, Amazon exercised its warrants to acquire a minority stake in Air Transport Services Group, the parent company of Amazon Air sub-lessor Air Transport International. The deal was valued at $131 million for 13.5 million shares in the company. Amazon also holds warrants to acquire a minority stake in Atlas Air Worldwide Holdings, the parent company of Atlas Air. In January 2023, Amazon launched Amazon Prime Air in India in partnership with QuikJet. The service will use two branded Boeing 737-800 freighters to deliver goods in four metro cities: Delhi, Mumbai, Hyderabad, and Bengaluru. The company plans to increase the number of dedicated freighters in India to six by the end of 2023, and will also continue to utilize the cargo space of other passenger airlines.
