NORTH CHARLESTON, S.C. – The first Boeing 787-9 Dreamliner aircraft assembled at the company’s South Carolina plant has been delivered.

The company said Tuesday that the stretch version of the standard Dreamliner has been delivered to United Airlines after assembly was completed in January. Test flights were conducted last month.

The aircraft is 20 feet longer and carries more passengers than the standard 787 Dreamliner. It’s also the 250th Dreamliner delivered by the company.

Two years ago, workers at Boeing’s plant in North Charleston began fabrication and assembly work on the rear and mid-fuselage sections for the first Boeing 787-9.

Those parts were delivered to the Boeing plant in Everett, Washington, for final assembly.

Work on assembling the first 787-9 in South Carolina began last November.
