The Boeing 787 Dreamliner is an American long-haul, mid-size widebody, twin-engine jet airliner made by Boeing Commercial Airplanes. Its variants seat 242 to 335 passengers in typical three-class seating configurations. It is Boeing's most fuel-efficient airliner and is a pioneering airliner with the use of composite materials as the primary material in the construction of its airframe. The 787 was designed to be 20% more fuel efficient than the Boeing 767, which it was intended to replace. The 787 Dreamliner's distinguishing features include mostly electrical flight systems, raked wingtips, and noise-reducing chevrons on its engine nacelles. It shares a common type rating with the larger Boeing 777 to allow qualified pilots to operate both models.

The aircraft's initial designation was the 7E7, prior to its renaming in January 2005. The first 787 was unveiled in a roll-out ceremony on July 8, 2007 at Boeing's Everett factory. Development and production of the 787 has involved a large-scale collaboration with numerous suppliers worldwide. Final assembly takes place at the Boeing Everett Factory in Everett, Washington, and at the Boeing South Carolina factory in North Charleston, South Carolina. Originally planned to enter service in May 2008, the project experienced multiple delays. The airliner's maiden flight took place on December 15, 2009, and completed flight testing in mid-2011. Boeing has reportedly spent $32 billion on the 787 program.
