Boeing 767-400ER

The 767-400ER was Boeing's first wide-body to come from two fuselage stretches. It is 6.43 m longer than the -300, and raked wingtips add 4.36 m (14.3 ft) of span. It also brought a cockpit updated with LCD screens, redesigned landing gear and a 777-style Signature Interior.

Delta launched it in March 1997 to replace its Lockheed L-1011 TriStars, and Continental followed in October 1997 to replace DC-10s. It first flew on 9 October 1999 and entered service with Continental on 14 September 2000, with FAA approval for 180-minute ETOPS before its first revenue flight.

Because its fuel capacity was not increased, the -400ER has less range than the earlier ER models. Only 37 were delivered, all to Delta and Continental (now United). One more was built as a testbed for the cancelled E-10 programme and later sold to Bahrain as a VIP transport.
