Delta Air Lines took delivery of its first A330-900, one of 35 A330neos the Atlanta, Georgia-based airline has on order. With new fuel-efficient engines, aerodynamic improvements, and the advanced Airspace by Airbus cabin the A330-900 will give Delta a premier long-haul, widebody aircraft with exceptionally low operating costs. Delta was the launch customer for the A330-900, ordering 25 in November 2014 and an additional 10 last year. With the addition of the A330-900, Delta is now operating both of Airbus' newest widebody models. It has 13 A350-900s in its fleet with another 12 on order. Delta operates more than 265 Airbus aircraft including A321s and A220s, and the airline's order backlog with Airbus exceeds 270 including 100 A321neos. Delta is one of the world's leading airlines, an industry pacesetter.
