1. The Boeing 737
The Boeing 737 is a narrow-body aircraft produced by Boeing Commercial Airplanes at its Renton Factory in Washington. As of December 2019, 15,156 Boeing 737s have been ordered and 10,571 delivered.
In December 1967, Boeing delivered the first production 737-100 to Lufthansa. The plane eventually earned the nickname Bobby, after a character in a children's book the airline would hand out to young passengers. In 1981, Boeing launched the second generation 737, dubbed the Classic.
Boeing launched the third-generation 737 in 1993. In 2011, Boeing launched the fourth-generation 737 called the Max. The plane eventually entered service in 2017. The 737 Max comes with updated avionics, turbofan engines, new wings, and avionics.
2. The Airbus A320
Airbus produced the 8,000th aircraft in the A320 family (the A318, A319 A320 and A321 single-aisle jets, as well as the -neo variations) in February 2018. The A320neo rolled off the production lines in Tianjin and was delivered to Air China. As at end-February 2018, a total of 8,029 aircraft had been delivered.
The first A320 was put into operation in 1988, more than 20 years after the first Boeing 737 was delivered.
The A320 is currently manufactured in four countries: France, Germany, China and the United States. Airbus could potentially have manufactured 15,000 of the A320 in the 2020s! The aircraft manufacturer is currently producing 50 aircraft a month, which is said to reach 60 aircraft a month in 2019.
3. The Boeing 747
More than 1,500 of the Boeing 747 aircraft were produced (1,543 aircraft have been delivered at last count), a symbolic milestone which was officially made in June 2014. The aircraft is manufactured in a plant in Everett (WA).
The first aircraft with a wide fuselage (for transporting up to 467 passengers) was unveiled at the Paris Air Show in 1969. Nicknamed "Jumbo Jet", the aircraft was, for a long time, the largest commercial transport aircraft, before the A380 entered the picture in the 2000s.
4. The Boeing 777
Boeing delivered the 1,500th "Triple Seven" aircraft in July 2017, 23 years after its maiden flight. A total of 1,534 aircraft had been delivered as at December 31, 2017. An incredible performance for a super-jumbo, long-range, twin-engine (the biggest in the world), twin-aisle jet that can transport between 300 and 550 passengers.
The program will go in a new direction in 2020 with the launch of the 777X series, which is expected to enter into service in 2020. Since August 2017, the production rate for the 777 (one of Boeing's most profitable models) has slowed down to 5 aircraft a month.
5. The Airbus A330
Since 1991, a total of 1,393 of the long-range, medium-capacity A330 aircraft have been produced. A total of seven aircraft is currently being produced every month. A re-engined A330neo took to the skies for its maiden flight on October 19, 2017 in Toulouse.
The production of the A330-800 began in fall of 2018. Safran is involved in this new program, notably as the exclusive engine nacelle supplier.
