I am mystified as to why the Boeing company has been allowed to be a miserable failure in its corporate strategy
I agree with respect to their narrowbody line-up - they should have bitten the bullet when the neo was launched and gone ahead with an all-new single-aisle. At the time, however, they were stretched on the 787 and couldn't persuade Chicago they should do it - something Airbus counted on at the time.
However, having finally got he 787 rocking, they are determined to strangle the A330neo at birth and may actually manage it judging by the aggressive terms they are putting out at present. Of course RR's troubles are playing into their hands too. While the A350-900 is a clear success, the 787-8 (newly re-invigorated to match the -9) through to the -10 is likely to dominate the mid-size widebody market for years to come. The 777X is a different story though - as is the A350-1000.
