Boeing 747-400 vs. Airbus A350-900

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.

Launched in 2013, the Airbus A350-900 is a long-haul, wide-body aircraft designed for high-capacity travel. The modern twin-engine aircraft offers a combination of range, comfort, and fuel efficiency.

The A350-900, with a length of 219.2 feet (66.8 meters) and a wingspan of 212.4 feet (64.8 meters), stands out for its considerable size. Its wing area of 4,757.6 square feet (442.0 square meters) contributes to its aerodynamic efficiency. The aircraft accommodates 319 passengers in a typical three-class configuration. Its design prioritizes passenger comfort, incorporating features such as a quieter cabin and advanced air systems for a more pleasant travel experience. Equipped with Trent XWB turbofan engines that deliver a total thrust of 148,000 lbf (660.0 kN), the A350-900 boasts significant fuel efficiency and reduced environmental impact. With a fuel capacity of 37,248 US gallons (141,000 liters), the aircraft achieves a range of 8,300 nautical miles (15,372 kilometers), enabling airlines to operate on extensive long-haul routes without stopovers.

In the competitive field of wide-body aircraft, the A350-900 challenges models like the Boeing 787-9 Dreamliner and the Boeing 777-200ER. It is recognized for its innovative use of materials, including extensive carbon-fiber-reinforced polymer, which contributes to weight reduction and overall efficiency. Key operators of the Airbus A350-900, such as Qatar Airways, Cathay Pacific, Lufthansa, and Delta Air Lines have utilized the aircraft for its operational flexibility and economic performance. The A350-900 serves a variety of long-range routes from domestic cross-country flights to international long-haul routes.

The Airbus A350-900's introduction into the market was a significant step in Airbus's strategy to offer cutting-edge, efficient aircraft. Its development reflects the manufacturer's response to airlines' demands for sustainable, high-capacity, and long-range travel solutions.
