Boeing is advancing toward a mid-decade series of incremental improvements to the 777 aircraft - dubbed the 777+ - which include the possibility of increasing the wingspan of the long-range twin, said vice-president of Boeing Commercial Airplanes business development Nicole Piasecki.

Among other possible improvements are flightdeck upgrades, similar to those on the 747-8, adding additional avionics capability for the crew without changing the display area.

Further, Boeing and General Electric are exploring ways to introduce GEnx engine technology into the GE90, which is exclusively available on the 777 family.
