Boeing 737 MAX 10 vs. Boeing 747-400

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.

The Boeing 747-400, a major development in the iconic 747 series, debuted in 1988 and quickly became one of the most recognizable aircraft in the world. Known as the "Queen of the Skies," this wide-body airliner redefined long-haul travel with its unparalleled range and capacity.

With a commanding presence, the 747-400 stretches 231.9 feet (70.7 meters) in length and boasts a wingspan of 211.4 feet (64.4 meters). The -400 featured reinvented wingtip extensions and winglets which improved the aircraft's fuel efficiency by 4%. Its distinctive second floor hump and four-engine configuration make it a standout at any airport. The 747-400's design accommodates up to 416 passengers in a typical three-class layout, making it one of the largest passenger airliners at the time of its introduction. The -400 variant was later succeeded by the newer 747-8I.

The 747-400 had three engine options; Pratt & Whitney PW4000s General Electric CF6s, or Rolls-Royce RB211s. Each 747-400 had a thrust of about 56,000 lbf (249.0 kN), summing up to an impressive total of 224,000 lbf (996.0 kN) across the 4 powerplants. This immense power, coupled with a fuel capacity of 57,061 US gallons (216,000 liters), allows the 747-400 to achieve a range of 7,284 nautical miles (13,490 kilometers). This exceptional range capability opened up numerous long-haul and transoceanic routes, reducing the need for stopovers and changing the face of international travel.

In the commercial aviation market, the Boeing 747-400 was a direct competitor to other large aircraft such as the Airbus A340. However, its unique features, like the upper deck and expansive cargo capacity, gave it a special place in the hearts of aviation enthusiasts and professionals alike. The 747-400 was operated by airlines such as British Airways, Qantas, Lufthansa, United Airlines, and Air France. These were among many other operators that used the 747-400 for their flagship international routes. Its spacious cabin and long-range abilities made it ideal for high-profile and high-density routes, offering passengers a unique and comfortable flying experience.

The Boeing 747-400's legacy goes beyond its impressive technical specifications. It symbolizes a significant era in aviation history, where the pursuit of connecting distant parts of the world became a reality. The aircraft's production, which spanned over two decades, is a testament to its enduring appeal and the pivotal role it played in shaping modern air travel. Today, while newer, more fuel-efficient aircraft have started to replace the 747-400, its iconic status and contribution to the airline industry continue to be celebrated. The Boeing 747-400 remains an enduring symbol of the romance and grandeur of flying, representing a bygone era of luxury, scale, and ambition in aviation. Lufthansa, Air China, and Asiana Airlines are some of the last airlines to hold onto their last 747-400s.
