Delta Air Lines fleet

As of May 2025, the Delta Air Lines fleet consists of 986 mainline aircraft, making it the third-largest commercial airline fleet in the world. Prior to its 2008 merger with Northwest Airlines, Delta with few exceptions 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 for other airlines. Delta operates the world's largest passenger subfleets of the 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. As of December 2024, Delta's average fleet age is 14.9 years.
