During the early 1980s Boeing began to study the possibility of a stretched development of the 767-200 aircraft. The result was the development of the Boeing 767-300, which is a 21ft stretch of the original design.

The stretched version entered service in September 1986.

By 2005 a total of 104 Boeing 767-300 airplanes had been ordered and deliverd: ANA (34), Delta (28),  Jal (22), Asiana (9), Air China (4), Shangahai Airlines (4), Air Algerie (3).

The extended range  version of the stretch (767-300 ER) took the 767 into a league of it's own.
