The 777X beats the 747 for wingspan and engine size Stay informed: Sign up for our daily and weekly aviation news digests. The Boeing 777-9 is the longest commercial jet to date. We will have to wait and see exactly what layouts the 777-9 takes, but it will be close to the 747-8. Lufthansa operates the 747-8 in a four-class configuration with 364 seats, Korean Air and Air China slightly more. It is rated to a maximum of 563, however. The newer (and larger) 747-8 has a typical capacity of 410, according to Boeing (this is in a three-class configuration). The smaller 777-8 will offer a capacity of around 384 and closely competes with the A350-1000. The 777-9 (the first to launch) offers a capacity of up to 426 (in a two-class configuration, according to Boeing data). There will be two versions of the 777X, the larger 777-9 and the smaller 777-8. To see how the 777X offers an alternative to the 747, just look at the passenger capacities. The Boeing 777X is undergoing test flights and will hopefully see the first deliveries by the end of 2023. To offer the size (and cost) needed, the 777X builds on the success of the 777 but will still offer efficiency improvements through its engines and wing design. The Boeing 787 and Airbus A350 were developed to take on-demand for more efficient widebodies, using a new clean-sheet composite construction. The internal fuselage space is increased slightly, though, by using thinner walls and more efficient insulation. It offers many improvements but keeps the same base design and metal fuselage construction as the 777.

It was launched in 1994 and has moved through several variants since then. The Boeing 777 has been the best-selling widebody aircraft to date. And although it does not feature the clean-sheet design of the 787, it takes on many of its improvements and avionics and will have a similar cockpit to aid pilot commonality. The 747 is now, of course, heading towards the end of production, but the 777X is targeted as a replacement. It is the continuation of the popular Boeing 777 series but also has a close relationship with Boeing’s other widebodies.

The larger 777-9 takes over from the Boeing 747, offering almost the same capacity, with a longer fuselage and wider wingspan. The largest engines to date, the highest capacity of a twinjet ever, and improved efficiency over the 777 and, of course, any quadjet. The upcoming Boeing 777X promises a lot for both airlines and passengers.
