There are 4 models in the 737 MAX generation: the MAX 7, 8, 9 and 10. The MAX 7 is originally based on the 737-700, the MAX 8 on the -800, the MAX 9 on the -900 and the MAX 10 is a larger version of the MAX 9. The 737 MAX generation is fitted with 2 high-bypass CFM International Leap 1-Bs, replacing the CFM56s used on planes in the Classic generation and the NG. The 1st model in the MAX generation is the MAX 7. It was intended to start commercial operations in 2019 but due to the worldwide grounding of the MAX generation (please see my previous article on the 737 MAX groundings for more information about this subject), this didn’t happen. The model took less than 100 orders (that’s pretty low for Boeing!). 40 MAX 7s were due to be launched with Southwest Airlines in January 2019 but all the orders were deferred: 23 of its orders to 2021, 12 to 2023 and 11 to 2024. The model is 35.6 meters long, has a maximum seating of 172 passengers and a 2 class seating of between 138 and 153 passengers. UTair Aviation (a Russian low-cost airline) ordered 30 and WestJet (a Canadian low-cost airline) ordered 22 of the type. The 2nd model in the MAX generation is the MAX 8. It started commercial operations successfully in 2017 but was grounded like all other MAX models. The MAX 8 is 39.5 meters long, has a maximum seating of 210 passengers and a 2 class seating of between 162 and 178 passengers. As of February 2019, 3002 MAX 8s were ordered, the biggest customers being Southwest, who ordered 280 aircraft and Spice Jet (an Indian low-cost airline), who ordered 206. A longer version of the MAX 8 called the MAX 200 has also been produced, with a 2 class seating of 210 passengers. Ryanair ordered 100 MAX 200s.
The 3rd model in the MAX generation is the MAX 9. It entered service in March 2018. The total amount of orders (as of February 2019) for the model is 387, the 2 biggest customers being Lion Air (an Indonesian low-cost airline), who ordered 189 aircraft and United, who ordered 85. The MAX 9 is 42.2 meters long, has a maximum seating of 220 passengers and a 2 class seating of between 178 and 193 passengers. The 4th and last model in the MAX generation is the MAX 10. It was due to enter service this year but couldn’t due to the grounding of all 737 MAXs. 511 MAX 10s were ordered as of February 2019 and the 2 biggest customers for the model were United, who ordered 100 aircraft and VietJet Air (a Vietnamese low-cost airline), who ordered 80. The MAX 10 measures 43.8 meters, has a maximum seating of 230 passengers and has a 2 class seating of between 188 and 204 passengers. So, as we can see, many 737 MAXs were ordered, but very few were delivered because of its worldwide grounding. It has now been over 1 year since the grounding, and the MAX still isn’t allowed to fly.
