The A330/A340 Family concept is unique: one basic airframe is available in six different configurations, powered by two or four engines. The twin-engine A330 is optimised for highest revenue generation and the lowest operating costs from regional segments to extended range routes, while the four-engine A340 provides versatility on the most demanding long-range and ultra-long-range flights.

The A330/A340 Family is composed of six jetliner versions that share the same fuselage cross-section and offer significant commonality with the optimum mix of operating characteristics in terms of aircraft size, range and economics.
