Achieved 8.7 hours daily utilisation and 99.64 per cent reliability rate in first 12 months of operation. All early aircraft with Rolls-Royce engines; first with PW2040 power (N753JM) was flown 20 February 2002, before delivery to Northwest Airlines.

CUSTOMERS: Launch customer Condor Flugdienst ordered 12 firm, with 12 options, on 2 September 1996; Icelandair ordered two, with Rolls-Royce engines, in June 1997, for delivery in second quarter 2001 and second quarter 2002. Boeing 757 production terminated in 2004.

COSTS: US$82.0 million to US$89.5 million (2002 and 2003). Seat-mile operating costs estimated at 10 per cent lower than those of 757-200.

DESIGN FEATURES: Fuselage stretched by 7.11 m (23 ft 4 in) 4.06 m (13 ft 4 in) ahead of the wing and 3.05 m (10 ft 0 in) aft - to provide 20 per cent more passenger accommodation and nearly 50 per cent more cargo volume than 757-200; typical accommodation 243 passengers in two-class configuration or up to 280 in single class with pitch of between 71 and 74 cm (28 and 29in). Other features include strengthened wings, engine pylons, high-lift devices and landing gear; strengthened overwing exit body section; new wheels, 26-ply tyres and brakes; nosewheel spray deflector; retractable tailskid, similar to those of 767-300 and 777-300, with 'body contact' indicator on flight deck; redesigned cabin interior based on 'Next-Generation' 737s, with upgraded environmental control system, larger precooler, more powerful fans, and vacuum lavatories with single-point drainage.
