History
The first 737-100 entered service in February 1968 with Lufthansa. The same year the 737-200 entered service. The original 737-100 and 737-200 variants were powered by Pratt & Whitney JT8D low-bypass engines and had a capacity for 85 to 130 passengers. Introduced in 1984, the 737 Classic: 300/400/500 variants were re-engined with CFM turbofans and had a higher capacity with 110 to 168 seats. Introduced in 1997, the 737 Next Generation (NG) 600/700/800/900 variants have updated CFM turbofans and a much higher capacity with a maximum of 108 to 215 passengers.

The 737 was the highest-selling commercial aircraft until being surpassed by the Airbus A320 family in October 2019.

737 MAX
The 737 MAX was designed to be a direct competitor with the A320neo. However, the 737 MAX was grounded worldwide from March 2019 to November 2020 following two fatal crashes caused by the Maneuvering Characteristics Augmentation System (MCAS).
