Boeing 737 MAX 7 vs. Boeing 737 MAX 10

The Boeing 737 MAX 7 is a narrow-body, twin-jet aircraft, and the smallest variant in the re-engineered 737 MAX family. The MAX 7 was originally announced in 2016, but has yet to fly for an airline as of 2023. It had its first flight on March 16, 2018, from the Boeing factory in Washington. The MAX 7 variant will reportedly get certification from the U.S. Federal Aviation Administration by April 2024, which will allow carriers to start flying the aircraft in late 2024. Southwest Airlines is expected to be the launch operator for the MAX 7. The 737 MAX 7 is designed to offer enhanced range and capacity for short to medium-haul flights, catering to airlines seeking a modern and flexible solution for their fleets. It is based on the original 737-700, and features very minor modifications in terms of size. It is expected to fly 1,000 nautical miles farther than the -700 with, 18% lower fuel costs per seat.

At 116.7 feet (35.6 meters) in length with a wingspan of 117.8 feet (35.9 meters), the 737 MAX 7 is adept at operating in diverse airport environments, including those with runway and size constraints. The aircraft typically seats 153 passengers, providing a blend of comfort and efficiency that is attractive for airlines operating regional routes. Powered by two CFM International LEAP-1B engines, the MAX 7 achieves a total thrust of 58,600 lbf (260.0 kN). It has a fuel capacity of 6,816 US gallons (25,800 liters), supporting a range of 3,850 nautical miles (7,130 kilometers). With a cruise speed of 521 mph (839 km/h), the 737 MAX 7 offers airlines an efficient means to cover short and medium distances.

Competitors for the MAX 7 include aircraft from Airbus like the A319neo and A220, and the E2 series from Embraer. Airlines such as Southwest Airlines and WestJet have selected the Boeing 737 MAX 7 for its operational flexibility and economic performance. The aircraft's capability to efficiently serve a range of regional routes makes it a valuable addition to airline fleets, especially for carriers looking to optimize their domestic and short-haul networks.

The Boeing 737 MAX 10 is the largest variant in the 737 MAX series, representing Boeing's expansion of its narrow-body, twin-engine offerings for the commercial aviation market. Launched in 2017, the MAX 10 was developed in response to airlines demanding a larger model than the MAX 9. The announcement for the MAX 10 was quickly followed by 240 orders and commitments from more than ten customers. The United States' aviation regulator, the FAA, cleared Boeing to begin certification flight testing of its 737 MAX 10 in November of 2023. Deliveries are being anticipated for early 2025.

The 737 MAX 10, with its extended fuselage, offers a greater passenger capacity compared to its siblings in the MAX series at 143 feet (43.79 meters). This increase in size allows airlines to accommodate more passengers per flight, optimizing efficiency and profitability, particularly on popular short to medium-haul routes. Equipped with advanced CFM International LEAP-1B engines, the MAX 10 delivers over 58,000 pounds of thrust. The slight stretch of the MAX 10 allows the jet to retain the existing wing design and LEAP engines from the MAX 9, with a trailing-link main landing gear being the only major change.

In the market, the Boeing 737 MAX 10 competes with aircraft like the Airbus A321neo. Both are very similar in terms of seating capacity, and range, but the MAX 10 does fall short in terms of field performance. Boeing predicts that the MAX 10 will yield a 5% lower trip cost and seat cost compared to the A321neo. It provides airlines with an alternative option in the narrow-body segment, offering a balance of capacity, range, and efficiency.

Various airlines have shown interest in the 737 MAX 10 for its ability to meet the demands of modern air travel. It is expected that United Airlines, Korean Air, Alaska Airlines, and Ryanair will have some of the largest fleets of MAX 10s. The MAX 10's capabilities make it an attractive choice for carriers looking to expand their network and serve densely populated routes efficiently.
