The 767-400ER is the final extended variant and was launched in 1997 on an order for Delta Air Lines and Continental Airlines to replace their aging Lockheed L-1011 andMcDonnell Douglas DC-10 fleets, respectively, following both airlines rejection of Boeing's previous 777-100X proposal. Other airlines also placed orders, but these were eventually canceled or converted to other Boeing models. The 767-400ER is a major development over the 767-300. The -400ER was stretched 21.1 ft (6.43 m) from the -300 for a total of 201.4 ft (61.4 m). It also featured a new glass cockpit, redesigned wings with a wingspan increase of 14.3 ft (4.36 m) over the previous two variants, larger passenger windows, new passenger cabin and redesigned landing gear. The -400ER is the only 767 variant to also feature "raked" wingtips for increased fuel efficiency. Its first flight was on October 9, 1999, and entered into service with Continental Airlines on September 14, 2000. This variant is only available as the 767-400ER, as there was no 767-400 variant. However it has less range than the other two ER variants.
