The Airbus A330 was launched as a twin-engined sister to the four-engined Airbus A340 in 1987. Two sizes of the planes are offered: the baseline Airbus A330-300, which was the first variant, and the shorter fuselage Airbus A330-200.
The A330-300 entered the service in January 1994 with the smaller, longer-range A330-200, following in April 1998.
The production of A330 aircraft is going ahead with more than 1000 aircraft delivered. About 50% or them are A330-200 and 50% are A330-300.
Currently Airbus is also launching the production of the modified versions of airplanes with new engines, wing and avionics. The new model line is called Airbus A330neo. The plan is to make two versions of airliners – the shorter one A330-800neo and the stretched one A330-900neo. The first planes of the A330neo generation are expected to enter service at the beginning of 2019.
