Airbus froze the development of the A350-800 and then let it slip out of the program (it's never officially canceled). The A330neo became the replacement for the A350-800. Was this the right decision? Is the A330neo the better airplane?
We saw the A350-800 in its final form had a problem competing with Boeing's 787. This created a problem for the Airbus widebody program below 300 seats.
After a thorough investigation, Airbus found a way to update the A330 to take the place of the A350-800. We use our airliner performance model to find out how well the replacement performs.
