A Japanese airline Thursday finalized an order for 40 Boeing wide-body airplanes, including 14 787-9 Dreamliners partially produced in North Charleston.

All Nippon Airways firmed up the $13 billion order at list prices originally announced as a commitment in March. The order includes 20 777-9Xs and six 777-300ERs as part of the airlines's long-haul fleet renewal. The 777s are produced in Washington state.

"The aircraft we have selected will enable us to modernize and expand our fleet further as we seek to become one of the world's leading airline groups," said Shinichiro Ito, president and CEO of ANA Holdings. "These new aircraft will give us maximum flexibility and improved fuel efficiency and will allow us to meet the growth in demand, both internationally and in our domestic Japanese market."

ANA, the launch customer of the 787, becomes the world's largest customer for the Dreamliner with a total of 80 airplanes ordered. The airline currently operates 29 787s with 51 more to deliver, including 43 787-9s. Airlines generally get discounts for airplane orders and not pay list prices.

The 787-8 is assembled in North Charleston. Parts for the 787-9 are produced here, and it is currently assembled in Everett, Wash. Starting this fall, the 787-9 will be produced locally as well. Boeing announced Wednesday the biggest version of the Dreamliner family, the 787-10, will be produced exclusively in North Charleston, starting in 2017.

"This order from ANA demonstrates the strength of our 50-year partnership and we are proud to make history with ANA once again," said Boeing Commercial Airplanes President and CEO Ray Conner. "We are honored that ANA has decided to continue operating an all-Boeing, wide-body fleet that consists of 767s, 787s, 777s and now the new 777X family of airplanes."
