Boeing (BA.N) said on Sunday it was confident of filling the bridge between current and future models of its two most profitable jets, the long-haul 777 and short-range 737, and dismissed plans by rival Airbus to overhaul its own A330 model. Sales chief John Wojick told Reuters he was confident of selling enough of the current 777-300ER, which is sold out until 2017, to fill the gap until a new revamped 777X version enters service in 2020, without having to cut production.
