ABOUT
The Airbus A330neo ("neo" for "New Engine Option") is a wide-body airliner developed by Airbus from the Airbus A330 (now A330ceo – "Current Engine Option").[4] A new version with modern engines comparable with those developed for the Boeing 787 was called for by operators of the original A330 series. It was launched on 14 July 2014 at the Farnborough Airshow, promising 14% better fuel economy per seat. It is exclusively powered by the Rolls-Royce Trent 7000 which has double the bypass ratio of its predecessor.
The A330-900 retains the fuselage length of the A330-300 and the similarly sized four-engined A340-300. Cabin optimisation allows ten additional seats on the A330-900 (310 passengers) with 18-inch-wide economy seats.[15] The -900 should travel 6,550 nmi (12,130 km; 7,540 mi) with 287 passengers (440 max).[74]

Delta expects a 20 percent reduction in operating cost per seat over the Boeing 767-300ER aircraft it replaces.[75]

Further reconfiguration of cabin facilities enables the –900 to seat up to 460 passengers in an all-economy layout.[76] This exceeds the existing 440-seat maximum exit limit allowed by the type certificate, and requires a modification of the Type-A exit doors to meet emergency exit requirements.[77] In November 2019, maximum accommodation increased to 460 seats, through the installation of new 'Type-A+' exits, with a dual-lane evacuation slide.[78]

Based on Kyo350XWB's A330-900, and GalacticaAsia's A330-300RR.
