N409DX: Delta Air Lines Airbus A330-900NEO

The Airbus A330 is a wide-body airliner made by Airbus. In the mid-1970s, Airbus conceived several derivatives of the A300, its first airliner, and developed the A330 twinjet in parallel with the A340 quadjet. In June 1987, Airbus launched both designs with their first orders. The A330-300, the first variant, took its maiden flight in November 1992 and entered service with Air Inter in January 1994. The slightly shorter A330-200 variant followed in 1998. In 2014, Airbus launched the A330neo, re-engined with Trent 7000 turbofans, which entered service in November 2018. The Airbus A330-900 maintains the A330-300's fuselage dimensions with 10 more seats thanks to cabin optimisation.[154] With modern Trent 7000 engines and redesigned winglets, it should burn 14% less fuel per seat than the A330-300 over a distance of 4,000 nmi.[156] It should travel 6,550 nmi (12,130 km) with 287 passengers in a standard configuration.[157]
