The Airbus A320 family consists of short- to medium-range, narrow-body, commercial passenger jet airliners manufactured by Airbus. The family includes the A318, A319, A320 and A321, plus the ACJ business jet. The A320's are also named A320ceo (current engine option) after the introduction of the A320neo. Final assembly of the family in Europe takes place in Toulouse, France, and Hamburg, Germany. Since 2009, a plant in Tianjin, China, has also started producing aircraft for Chinese airlines. In April 2013, Airbus has started construction work on a new production facility for the A319, A320 and A321 variants in Mobile, Alabama. The aircraft family can accommodate up to 220 passengers and has a range of 3,100 to 12,000 km (1,700 to 6,500 nmi), depending on model.

The Airbus A340 is a long-range four-engine wide-body commercial passenger jet airliner. Developed and produced by Airbus Industrie the A340 was assembled in Toulouse, France. It seats up to 375 passengers in the standard variants and 440 in the stretched −600 series. Depending on the model, it has a range of between 6,700 to 9,000 nautical miles (12,400 to 17,000 km). It is similar in design to the twin-engined A330 with which it was concurrently designed. Its distinguishing features are four high-bypass turbofan engines and three-bogie main landing gear.

Airbus manufactured the A340 in four fuselage lengths. The initial variant, A340-300, which entered service in 1993, measured 59.39 metres (194.8 ft). The shorter −200 was developed next, and the A340-600 was a 15.91 metres (52.2 ft) stretch of the −200. The −600 was developed alongside the shorter A340-500, which would become the longest-ranged commercial airliner until the arrival of the Boeing 777-200LR.

The Airbus A380 is a double-deck, wide-body, four-engine jet airliner. It is the world's largest passenger airliner; many airports have upgraded their facilities to accommodate it because of its size. Initially named Airbus A3XX, Airbus designed the aircraft to challenge Boeing's monopoly in the large-aircraft market; the A380 made its first flight on 27 April 2005 and began commercial service in October 2007 with Singapore Airlines.

The British Aerospace 146 (also BAe 146) is a regional airliner that was manufactured in the United Kingdom by British Aerospace, later part of BAE Systems. Production ran from 1983 until 2002. Manufacture of an improved version known as the Avro RJ began in 1992. A further-improved version with new engines, the Avro RJX, was announced in 1997, but only two prototypes and one production aircraft were built before production ceased in 2001. With 387 aircraft produced, the Avro RJ/BAe 146 is the most successful British civil jet programme.

The Boeing 727 is a midsized, narrow-body three-engined jet aircraft built by Boeing Commercial Airplanes from the early 1960s to 1984. It can carry 149 to 189 passengers and later models can fly up to 2,700 nautical miles (5,000 km) nonstop. Intended for short and medium-length flights, the 727 can use relatively short runways at smaller airports. It has three Pratt & Whitney JT8D engines below the T-tail, one on each side of the rear fuselage with a center engine that connects through an S-duct to an inlet at the base of the fin. The 727 is the only Boeing trijet, as a commercial design entering production

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 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 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 767 is a mid- to large-size, long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes. It was the manufacturer's first wide-body twinjet and its first airliner with a two-crew glass cockpit. The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design. Designed as a smaller wide-body airliner than earlier aircraft such as the 747, the 767 has seating capacity for 181 to 375 persons and a design range of 3,850 to 6,385 nautical miles (7,130 to 11,825 km), depending on variant. Development of the 767 occurred in tandem with a narrow-body twinjet, the 757, resulting in shared design features which allow pilots to obtain a common type rating 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 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 family of twin-engine, short- to medium-range, single-aisle commercial jet airliners. The MD-80 series were lengthened and updated from the DC-9. The airliner family can seat from 130 up 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 MD-80 series was followed into service in modified form by the MD-90 in 1995 and the MD-95/Boeing 717 in 1999
