Boeing said on Wednesday it will not increase 787 output unless sales improve, its clearest indication yet that its large jetliner production may have peaked for now.“If the market’s not going to demand it, we’re not going to go,” Chief Financial Officer Greg Smith said on the sidelines of an investor conference in New York organized by global investment bank Jefferies, confirming remarks made during the formal program.“It’s not the end of the world” if Boeing keeps 787 production at 12 a month instead of lifting it to 14 as planned, Smith said during the event.
