Last month Boeing revealed more details of the interior of the 777X which will give passengers a new level of comfort with airlines using the new jet, which will enter service in 2020, as a showcase for the latest interior products. Last year launch customer Lufthansa unveiled a new Business Class cabin concept for the 777X, which it will introduce in 2020. READ: First engines installed on the 777X The 777X comes in two models the – 9 and -8. The airline says its Business Class passengers can look forward to lie-flat beds with a length up to 220cm (86.6 inches), with a focus for those that lie on their side when sleeping.

The Business Class configuration on the Lufthansa 777-9 will be 1-2-1 and 1-1-1 giving direct aisle access for all passengers. Passengers will also have the greatest storage space of any aircraft and they will be able to control the in-flight entertainment from their own personal devices. What is more wireless device charging will be fitted to the 777-9. In a first, passengers can also opt for a suite that has greater desk space or one that has a longer bed. Emirates, the largest customer for the 777X with 150 on order says it will add Premium Economy to its offering with the new jet. The cabin is about 4 inches or 10cm wider than the current 777 and this has been achieved by re-sculpturing the interior ribs of the aircraft. This will mean physically a more spacious interior for all classes while windows that are 20 percent larger and repositioned higher will give a visually much greater sense of space. The aircraft also features the lower cabin pressurization and high humidity of the 787. It will have a fourth-generation composite wing and an all-new engine from General Electric the world’s foremost engine builder. The wing and engine combination will give the aircraft a 20 percent better fuel economy per seat than the 777.

The 777-9X seats more than 400 passengers, depending on an airline’s configuration choices. With a range of more than 15,185 km, the aircraft will have the lowest operating cost per seat of any commercial aircraft says, Boeing.

Boeing claims the second aircraft, the 777-8X, will be the most flexible jet in the world. The aircraft will seat 350 passengers and offer a range capability of more than 17,220 km. The 777X is a contender for the Qantas Sunrise Project to carry 300 passengers non-stop from Sydney to London.
