The Boeing 757-300, member of the popular 757/767 family of medium-sized airplanes, was launched Sept. 2, 1996. Designed to carry 243 passengers in a typical, mixed-class configuration, the 757-300 can accommodate up to 289 passengers in charter service, putting its capacity between that of the 757-200 and the 767-300. Because of its additional capacity, the 757-300 has about 10 percent lower seat-mile operating costs than the 757-200, which has the lowest seat-mile operating cost in its market segment. On Nov. 28, 2005, Boeing concluded the remarkable 23-year run of the 757 passenger airplane.
