Amazon Air (often branded as Prime Air) is a cargo airline operating exclusively to transport Amazon packages. In 2017, it changed its name from Amazon Prime Air to Amazon Air to differentiate themselves from their Amazon Prime Air autonomous drone delivery service. However, the Prime Air logo remains on the aircraft. Until January 2021, the airline had relied on wet-leasing its aircraft from other operators, but going forward it is looking to directly own some aircraft. On the planes the airline owns, the airline will still rely on others for CMI (crew, maintenance, and insurance) leases. History In late 2015, Amazon began trial cargo runs out of Wilmington Air Park under the code name Project Aerosmith. In December 2015, Amazon announced that it would begin its own cargo airline to expand its capability. In March 2016, Amazon acquired options to buy up to 19.9 percent of Air Transport Services Group's (ATSG) stock and began scheduled operations with 20 Boeing 767 aircraft. On January 31, 2017, Amazon announced that Amazon Air would make Cincinnati/Northern Kentucky International Airport (KCVG) its principal hub, and began operations on April 30, 2017. Amazon received $40 million in tax incentives and plans to begin construction on a facility with a sorting facility and parking space for over 100 cargo aircraft; the project is estimated to cost $1.5 billion. In December 2017 the company, which was named Amazon Prime Air, announced its rebranding as Amazon Air to avoid confusion with the Amazon Prime Air drone delivery service, although it continues to operate under the callsign "Prime Air". As of June 2018, Amazon Air had 20 of its 33 cargo planes based at the Cincinnati/Northern Kentucky International Airport (KCVG), with the rest flying point-to-point transit routes across the United States. Amazon Air was to move into office space at the former Comair headquarters by March 2018. Amazon leased 10 additional Boeing 767-300 planes from ATSG in December 2018. Amazon has completed a new regional air hub at Fort Worth Alliance Airport (KAFW) and does not airlift third-party packages. The new regional hub began operating on October 2, 2019. For 2019 and 2020, Amazon has committed to leasing 10 additional 767-300 aircraft from Air Transport Services Group, which would bring active aircraft to a total of 50. Phase one of the CVG sort facility, encompassing is scheduled for completion in 2020, while the remaining will be developed by 2025–2027
