Korean Air has taken delivery of its first Boeing 787-9.

The aircraft was built at Boeing’s factory in North Charleston, South Carolina.

“The 787 Dreamliner will be a key member of Korean Air’s fleet as we continue to introduce next-generation airplanes to our customers,” said Walter Cho, president of Korean Air. “The aircraft is fuel-efficient, quiet, has lower operating costs and is spacious and very elegant.”

The airline will deploy the aircraft on the domestic route between Seoul Gimpo and Jeju for a month for training and certification. The 787 will then be operated on flights to Toronto, Madrid and Zurich later this year.

“This milestone delivery adds yet another chapter in our long and successful relationship with Korean Air,” said Rick Anderson, vice president of Northeast Asia sales at Boeing Commercial Airplanes. “Korean Air continues to demonstrate its leadership in the global commercial airline industry and we are confident that the market-leading efficiency and comfort of the 787-9 Dreamliner will build onto their long-term success for many years to come.”

Korean Air has nine more 787-9s on firm order. Four more will be delivered in 2017 and the remaining five will join the fleet by 2019, according to Boeing.
