Is the loss for Airbus really so dramatic? Maybe having a complete line-up and being prepared in case demand had developed differently made it worth having this loss. Car manufacturers also don't run all models at a profit but still need a full line-up to retain customers. I don't think it's that different for airlines. Airbus makes their money with A320 (plus some from A330 and maybe at some point A350).
