Boeing (Chicago, Seattle, Wichita and Charleston) announced the completion of firm configuration for the 787-9 Dreamliner. Boeing reached this milestone after years of collaboration with airline customers and partners to determine the optimal configuration for the new stretch version of the Dreamliner.

Boeing has completed the trade studies required to finalize the airplane’s overall capability and basic design, allowing the airplane manufacturer and its suppliers to begin detailed design of parts, assemblies and other systems for the 787-9. As detailed designs are completed and released, production can begin. The first 787-9 delivery is scheduled for late 2013.

The 787-9 is the second member of the 787 family. A slightly bigger version of the 787-8, the airplane will seat 250-290 passengers, 16 percent more than the 787-8. The 787-9 will have a range of 8,000 to 8,500 nautical miles (14,800 to 15,750 km).
