The Delta Air Lines fleet consists of 1,004 mainline aircraft, making it the third largest commercial airline fleet in the world. Prior to its 2008 merger with Northwest Airlines, Delta mostly operated aircraft built in the United States. The merger introduced Airbus models, now the majority, into Delta’s fleet. Historically, Delta has favored used and older-generation aircraft to lower acquisition costs. Its in-house MRO division, Delta TechOps, plays a key role in efficiently managing the complexity of this diverse fleet, while also generating revenue servicing aircraft and engines for other airlines. Delta operates the world's largest passenger subfleets of Airbus A220, Boeing 717, Boeing 757, Boeing 767, and Airbus A330 aircraft. Wide-body aircraft including the Airbus A330, Airbus A350, and Boeing 767, are deployed on long-haul routes to Europe, Asia, Africa, Oceania, and South America. , Delta's average fleet age is 15.0 years.

Fleet renewal

, Delta continued to refresh its fleet of 975 mainline and 317 regional aircraft with orders of 294 new and more fuel-efficient aircraft with increased premium seating and cargo capacity to replace retiring aircraft, while modifying existing aircraft cabins to increase premium offerings and harmonize interiors. Since its merger with Northwest Airlines, Delta has retired its Boeing 737-700, 747-200 (freighters), 747-400, 777, and its McDonnell Douglas DC-9, MD-88, and MD-90 sub-fleets. During that time, Delta made innovative deals, including a lease of 88 used Boeing 717 aircraft from Boeing and Southwest Airlines in 2012, an order for 75 Bombardier CS100 (now Airbus A220-100) aircraft in April 2016 at a steep discount for less than $20m each, well below their $33.2m production cost, which led Boeing to accuse the manufacturer of dumping the aircraft, and the acquisition of purchase rights for 10 LATAM Airlines Airbus A350 aircraft on order as part of a deal to acquire a 20% equity stake in LATAM Airlines Group in September 2019.
