Delta Air Lines will continue refreshing its fuel-efficient, state-of-the-art fleet after executing options for 12 new Airbus A220-300 aircraft. Jan. 18, 2023, 8 a.m. Delta expects to welcome 26 state-of-the-art A321neos to its fleet this year, with a total of 155 purchase commitments through 2027.

Delta Air Lines is currently in the midst of a massive fleet modernization program focused on efficiency and international expansion. In early 2026, Delta made headlines by placing a firm order for 31 additional Airbus widebody aircraft, consisting of 16 A330-900s and 15 A350-900s, which will bring their A350 fleet to nearly 80 planes. Most significantly, in January 2026, Delta placed its first-ever direct order for up to 60 Boeing 787-10 Dreamliners. These ultra-efficient "10" variants will replace older, less efficient Boeing 767s and 777s on high-demand transatlantic and South American routes. On the domestic side, Delta is continuing to take delivery of the Airbus A321neo and has a large outstanding order for 100 Boeing 737-10 (the largest MAX variant). This diverse "mixed-fleet" strategy allows Delta to optimize for lower operating costs while offering passengers modern cabin features like larger overhead bins, 4K seatback screens, and better fuel economy across its global network.
