Don't see 330's making too much sense unless we're reeeally worried about 787 having delivery issues. Now, the 350, especially 350 1k gives us a 777 replacement and range no other jet has. An airframe to introduce rumored new luxury Polaris product. As well as the all so important fleet diversification we need. Imo, a successful formula for future is 50/50 737/320 family, and 50/50 787/350 family. Variants of such to try to puzzle together 756 replacement. Hope we get 350!!
