A350A330

A350A330 is not an official Airbus product designation. In aviation discussions, the term is sometimes used to describe a hypothetical aircraft concept that would combine elements of the Airbus A350 XWB family with those of the A330 family. There is no confirmed program or production plan under this name, and it has not been announced by Airbus.

Conceptually, a A350A330 would aim to offer a balance between the efficiency and modern systems associated with the A350 and the market positioning of the A330 family. Proponents envision a mid-sized widebody that could leverage advanced aerodynamics, an improved cabin, and common parts or maintenance practices with existing Airbus families to reduce lifecycle costs. The idea is often presented as a way to target routes and fleets requiring lower trip costs or specific range and capacity capabilities.

Design considerations in such a concept would likely include an all-composite or mixed-structure fuselage, modern avionics and cockpit systems, and wing technology drawn from the A350 line or from newer A330neo developments. Engine choices in speculative discussions typically point to current high-bypass modern engines, such as those used on the A350 XWB or A330neo family, to achieve competitive fuel efficiency and noise performance.

Development status remains purely speculative. No official study, grant, or program has been announced by Airbus, and any real-world realization would require substantial investment, certification, and market justification. The A350A330 concept is mainly of interest as a theoretical reference point in discussions of future widebody design tradeoffs and fleet optimization.
