Boeing Company expects to begin delivering improved 787 Dreamliner aircraft in the first half of the year.

A senior executive of Boeing Company said on Wednesday that they expect to start delivering improved versions of the 787-9 and 787-10 Dreamliner aircraft to airlines in the first half of this year, enabling longer flight times or increased cargo capacity. Darren Hulst, Boeing's vice president of commercial marketing, stated that improvements in the maximum takeoff weight of wide-body aircraft will increase airlines' flight distances by 400 miles or increase cargo capacity by 5 to 6 tons. "These aircraft are already in the production system, undergoing certification, and we expect them to start being delivered in the first half of this year," he told reporters at the Singapore Airshow. Hulst also mentioned that the aircraft manufacturer expects the larger 777X to be certified in the second half of this year, but it may not enter into service until next year.
