Boeing 757-300 vs. Boeing 787-9

The Boeing 757-300, an extended variant of the popular 757 series, is a narrow-body, twin engine aircraft serving medium-long haul routes. As a stretched version of the 757-200, the 757-300 was designed to accommodate a higher passenger capacity while maintaining the series' operational efficiency and versatility. The B753 entered the commercial aviation market in 1998 with the German airline Condor.

Sometimes referred to as the "flying pencil", the 757-300 has a rather long and skinny fuselage. It measures in at over 54 meters (178 feet), making it the longest, single-aisle twinjet ever built. The wingspan remains at 38.0 meters (124.7 feet), and the wing area is 185.3 square meters (1994.0 square feet), consistent with the 757 series design. The extended fuselage of the 757-300 allows it to carry a larger number of passengers, enhancing its appeal for airlines looking to maximize capacity on popular routes.

The typical seating arrangement in the 757-300 is designed to accommodate about 262 passengers. This configuration usually includes a dual-class layout, with the majority of the cabin dedicated to economy class in a 3-3 seat configuration, alongside a smaller business class section. This layout enables airlines to optimize the balance between passenger comfort and density, making the aircraft particularly suitable for high-demand, medium-range routes.

Powered by Rolls-Royce RB211s or Pratt & Whitney PW2043s the 757-300 is capable of delivering a maximum thrust of 387.0 kN (87,000 lbf), the Boeing 757-300 offers a range of approximately 6,295 kilometers (3,399 nautical miles). This range, combined with its passenger capacity, positions the 757-300 as a competitive option for airlines operating busy domestic and transcontinental routes.

In the market, the Boeing 757-300 faced competition from similar narrow-body aircraft, such as variants from the Airbus A321 series and the McDonnell Douglas MD-90. These aircraft offered comparable range and capacity, creating a competitive landscape in the segment of extended narrow-body airliners. Production for the 757-300 totaled just 55 aircraft. Airlines that have incorporated the Boeing 757-300 into their fleets include Continental Airlines (now merged with United Airlines), Delta Air Lines, and Icelandair. These carriers have utilized the aircraft's unique combination of capacity and range to efficiently serve a mix of domestic and international routes, underscoring the 757-300's utility in commercial aviation.

The Boeing 757-300, while not as widely produced as its shorter counterpart, the 757-200, still marks an important development in the evolution of the 757 series. Its extended fuselage and increased capacity cater to specific market needs, demonstrating Boeing's adaptability in responding to evolving airline requirements. As a variant of one of the most recognizable narrow-body aircraft families, the 757-300 continues to play a role in the global aviation industry, particularly in markets where capacity and efficiency are paramount.

The Boeing 787-9 is an extended variant of the 787 Dreamliner series, a family of wide-body, twin-engine jet airliners known for their fuel efficiency and range capabilities. First flown in 2013, the 787-9 was developed to provide additional seating capacity and range compared to its predecessor, the 787-8. This model caters to the needs of airlines for longer routes and increased passenger demand. Out of the 3 787 variants, the -9 is by far the best selling type. As of December 2023, there were 1113 Boeing 787s in airline service, comprising of 397 787-8s, 619 787-9s and 97 787-10s.

The 787-9 spans 62.8 meters (206.1 feet) in length, and 60.1 meters (197.2 feet) in wingspan. The aircraft's use of composite materials, making up a significant portion of its construction, contributes to its lighter weight and structural efficiency, leading to lower fuel consumption and reduced operational costs. Powered by two engine options, either the General Electric GEnx or the Rolls-Royce Trent 1000, the 787-9 delivers a total maximum thrust of 640.0 kN (142,000 lbf). These engines, combined with the aircraft's aerodynamic design, allow it to achieve a range of approximately 14,140 kilometers (7,635 nautical miles). This extended range makes the 787-9 suitable for a variety of long-haul international routes - such as Singapore to San Francisco, Auckland to New York, and Perth to London. These extreme long haul routes can have flight times north of 16 hours.

The aircraft typically accommodates around 290 passengers in a three-class configuration. The cabin features larger windows, higher humidity, and improved air pressure levels compared to traditional airliners. In the commercial aviation market, the Boeing 787-9 competes with other long-range wide-body aircraft such as Airbus' A350-900. Its introduction provided airlines with an option that blends efficiency, capacity, and range, making it a popular choice for various long-haul routes. Airlines that have incorporated the Boeing 787-9 into their fleets include All Nippon Airways, American Airlines, United Airlines, and Air New Zealand. These carriers utilize the aircraft's capabilities to efficiently serve a mix of high-demand routes, taking advantage of its operational efficiency and passenger appeal.

In summary, the Boeing 787-9 stands as a significant development in the Dreamliner series, offering enhanced capabilities in terms of passenger capacity and range. Its design and technological advancements represent an evolution in long-haul air travel, providing airlines with a versatile and efficient aircraft for their long-range operations.
