Sized between the Boeing 767-300ER and the Boeing 777-200, the 767-400ER features a lengthened fuselage; aerodynamic improvements, including additional wing span; increased takeoff weight capability; and an all-new main landing gear. The 767-400ER brings significant improvements in operating economics over competing airplanes in the 240- to 300-seat market. The payload capability, intercontinental range, passenger comfort and commonality with other Boeing jetliners give this airplane strong market appeal.
