All part of the narrative. I reckon they'll announce the 787 for mainline about mid next year..... when they announce that their magical transformation is on track to break even and return to profit and the 787 is the vehicle which will bring about that improved profitability.
A senior manager recently said. The mainline fleet age is commercial in confidence. Hence they report the "groups" fleet age.
Whilst one part of the group has a relatively young average fleet age, another part of the group has a distinctly older fleet age.
What the investment community has failed to realise due reporting a "group" fleet age is over investment in one part of the business & under investment in another.
