Its variants seat 242 to 335 passengers in typical 3-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 767, which is being replaced."@en . .
