The Boeing 737 Next Generation, commonly abbreviated as Boeing 737NG, is the name given to the −600/-700/-800/-900 series of the Boeing 737 aircraft. It is the third generation derivative of the 737, and follows the 737 Classic (−300/-400/-500) series, which began production in the 1980s. They are short- to medium-range, narrow-body jet airliners. Produced since 1996 by Boeing Commercial Airplanes, the 737NG series includes 4 variations and can seat between 110 to 210 passengers.

The B737-700C is a converted version where the passenger seats are removed so that the whole cabin can be used as cargo space. There is large cargo door on the left side of the fuselage.

The Boeing 747 is a wide-body commercial airliner and cargo transport aircraft, often referred to by its original nickname, Jumbo Jet, or Queen of the Skies. It is among the world's most recognizable aircraft and was the first wide-body ever produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was two and a half times larger in capacity than the Boeing 707, one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years

The 747-400 and earlier versions had proven to be a very popular freighter, carrying around half of the world's air freight.[123] To maintain this position, Boeing designed a freight variant of the 747-8, named the 747-8 Freighter or 747-8F. The company launched the freighter version on November 14, 2005.[124] The 747-8F is the initial model to enter service. As on the 747-400F, the upper deck is shorter than passenger models; the 18-foot-3 1⁄2-inch (5.575 m) stretch is just before and just aft of the wing. 747-8 Freighter was designed with a 975,000 lb (442,000 kg) maximum take-off weight with a payload capability of 308,000 lb (140,000 kg) and a range of 4,390 nmi (8,130 km).[125] Four extra pallet spaces were created on the main deck, with either two extra containers and two extra pallets, or three extra pallets, on the lower deck.[21] The 747-8F is expected to have a 16% lower ton-mile operating cost than the 747-400F and offer a slightly greater range.

The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was designed and built by Boeing Commercial Airplanes. It is the manufacturer's largest single-aisle passenger aircraft and was produced from 1981 to 2004. The twinjet has a two-crew member glass cockpit, turbofan engines, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design. Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 289 passengers for a maximum of 3,150 to 4,100 nautical miles (5,830 to 7,600 km), depending on variant. The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft

The Boeing 777 is a long-range wide-body twin-engine jet airliner manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and has a typical seating capacity for 314 to 451 passengers, with a range of 5,235 to 9,380 nautical miles (9,695 to 17,370 km), depending on the version. Commonly referred to as the "Triple Seven", its distinguishing features include the largest-diameter turbofan engines of any aircraft, six wheels on each main landing gear, a circular fuselage cross-section and a blade-shaped tail cone. Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between the 767 and 747. As Boeing's first fly-by-wire airliner, it has computer-mediated controls; it is also the first entirely computer-designed commercial aircraft.

The 777 Freighter (777F) is an all-cargo version of the twinjet, and shares features with the −200LR; these include its airframe, engines,[177] and fuel capacity. With a maximum payload of 226,000 lb (103,000 kg), cargo capacity is similar to the 243,000 lb (110,000 kg) of the 747-200F. The freighter has a range of 4,900 nmi (9,070 km) at maximum payload,[88] although greater range is possible if less cargo weight is carried

The Bombardier Dash 8 or Q-Series, previously known as the de Havilland Canada Dash 8 or DHC-8, is a series of twin-engined, medium range, turboprop airliners. Introduced by de Havilland Canada (DHC) in 1984, they are now produced by Bombardier Aerospace. Over 1,000 Dash 8s of all models have been built, with Bombardier forecasting a total production run of 1,192 aircraft of all variants through 2016

The McDonnell Douglas MD-11 is a three-engine medium- to long-range widebody jet airliner, manufactured by McDonnell Douglas and, later, by Boeing Commercial Airplanes. Based on the DC-10, it features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and smaller tailplane, new engines and increased use of composite materials. Two of its engines are mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It also features an all-digital glass cockpit that decreases the flight deck crew from the three required on the DC-10 to two by eliminating the necessity for a flight engineer.

The McDonnell Douglas MD-80 is a series of twin-engine, short- to medium-range, single-aisle commercial jetliners. It was lengthened and updated from the DC-9. This series can seat from 130 to 172 passengers depending on variant and seating configuration.

The MD-80 series was introduced into commercial service on October 10, 1980 by Swissair. The series includes the MD-81, MD-82, MD-83, MD-87, and MD-88. These all have the same fuselage length except the shortened MD-87. The series was followed into service in modified form by the MD-90 in 1995 and the Boeing 717 (originally MD-95) in 1999.
