The Boeing 757 is a narrow-body commercial passenger aircraft manufactured by Boeing Commercial Airplanes. It was launched by Eastern Air Lines and British Airways to replace the Boeing 727 and entered service in 1983. Passenger versions of the 757 can carry between 186 and 279 passengers, and have a maximum range of 3,100 to 3,900 nautical miles (5,900 to 7,200 km) depending on variant and seating configuration.[2] Production of the 757 ended on October 28, 2004 after 1,050 had been built.[1] The final aircraft was delivered to Shanghai Airlines on November 28, 2005. A total of 1,000 Boeing 757 aircraft were in airline service in October 2008.[3]The 757 (designated "7N7" during initial development)[4] was designed by Boeing to replace the Boeing 727 and complement the Boeing 767 on thin routes.

The Boeing 737 is a short to medium range, single aisle, narrow body jet airliner. Originally developed as a shorter, lower cost twin engine airliner derived from Boeing's 707 and 727, the 737 has nine variants, from the early -100 to the most recent and largest, the -900. Series -600 through -900 are still being produced.
First envisioned in 1964, the 737 entered service in 1968. Forty years later it has become the most ordered and produced commercial passenger jet in the world. It is Boeing's last surviving narrow-body airliner currently in production, sometimes serving markets previously filled by 707, 727, 757, DC-9 and MD-80/90 airliners. The 737 has been continuously manufactured by Boeing since 1967 with over 8,000 ordered and 5,857 delivered as of 2008.

The Airbus A300 is a short- to medium-range widebody aircraft. Launched in 1972 as the world's first twin-engined widebody, it was the first product of the Airbus consortium of European aerospace companies, wholly owned today by EADS. The A300 ceased production in July 2007, along with the smaller A310. Freighter sales for which the A300 competed are to be fulfilled by a new A330-200F derivative.[1]The mission requirements were given in 1966 by Frank Kolk, an American Airlines executive, for a Boeing 727 replacement on busy short- to medium-range routes such as US transcontinental flights. His brief included a passenger capacity of 250 to 300 seated in a twin-aisle configuration and fitted with two engines, with the capability of carrying full passengers without penalty from high-altitude airports like Denver. American manufacturers responded with widebody trijets, the McDonnell Douglas DC-10 and the Lockheed L-1011 Tristar, as twinjets were banned from many routes by.
