The 757-300 is a stretched version of the 757-200. The extra length allows it to carry 20 percent more passengers than the 757-200 and increases the available cargo volume by nearly 50 percent. Its seating capacity is between that of the 757-200 and the 767-300. Because of this, the 757-300 has about 10 percent lower seat-mile operating costs than the 757-200, which already 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, although most 757s are still service.
