Boeing, one day after announcing the record-breaking launch of the 777X, outlined (18-Nov-2013) the performance characteristics and a variety of features "that will make the newest member of the Boeing twin-aisle family the largest and most fuel-efficient twin-engine commercial jetliner in aviation history". Boeing noted that key innovations will make the 777X 12% more fuel efficient than its competitor, through the following features: an all-new composite wing based on the wing developed for the 787, aerodynamic advances such as a hybrid laminar flow control vertical tail and natural laminar flow nacelles, and all-new GE9X engines developed by GE Aviation. Boeing also said these new technologies will help the 777X deliver 10% lower operating economics than the competition. Boeing Commercial Airplane VP and GM of airplane development Scott Fancher said, "The 777X builds on the heritage of the 777-300ER and incorporates many advanced technologies designed for the 787 to create a new standard for widebody airplanes. It will truly be a worthy successor to the 777-300ER". Two models comprise the 777X family – the 777-8X, with approximately 350 seats and a range capability of more than 9300 nautical miles; and the 777-9X, with approximately 400 seats and a range of more than 8200 nautical miles. The 777-8X competes directly with the A350-1000 while the 777-9X is in a class by itself, according to Boeing. At 233 feet, the 777X composite wing has a longer span than today's 777-300ER. Its folding, raked wingtip delivers greater efficiency, significant fuel savings and complete airport gate capability, Boeing noted, adding that it allows access to the entire range of gates currently accessibly by the 777-300ER. Adding 787 technologies in the flight deck, flight controls and other systems is just the beginning. The 777X implements 787 technologies where they add value to our customers and increase commonality across Boeing's twin-aisle product family. Boeing also said it is exploring a number of innovations that will advance the passenger experience and create an interior passengers will prefer. For instance, the company will reposition and resize the windows to provide more ambient light inside and provide passengers with better views outside the cabin. A new interior architecture will make the 777X cabin even more spacious, leveraging the airplane's cross-section which is the widest in its class. The 777X is targeted for first delivery in 2020.

Global commercial aircraft deliveries fell in 2016 as Boeing again outsold Airbus; 2017 to be a peak
The global commercial aircraft fleet grew by 4% in 2016 and the year ended with an order backlog of more than nine years of production. Among the regions, North America still has the biggest and oldest fleet, but the lowest ratio of orders to aircraft in service. By contrast, Middle East has the fewest in service, but the highest ratio of orders to current fleet numbers.
This report gives an overview of the number of commercial aircraft deliveries in 2016 and the outlook into 2017 and beyond. It also looks at numbers in service and on order by region. It is based on preliminary numbers from the CAPA Fleet Database and guidance on 2016 deliveries from Airbus and Boeing, who have yet to announce final numbers.
The data indicate that total worldwide deliveries fell in 2016, the first such decline for six years, as a result of delays to new aircraft programmes. Boeing delivered more aircraft than Airbus for the fifth straight year, but its deliveries fell short of its 2015 level, while Airbus increased its numbers year-on-year. Total deliveries will likely rise again in 2017, but this may prove to be a peak year.
Lion Group 2016 fleet analysis: slower growth following 737 cancellations & increased focus on FSCs
Lion Group significantly slowed its rate of expansion in 2016 and cancelled 21 Boeing 737 orders. The Indonesia-based airline group took 36 aircraft in 2016 compared to 57 aircraft in 2015, as the rate of 737 deliveries was slashed in half from an average of two per month to one per month.
Most of the growth in 2016 was at Lion Group’s two full service airlines, Indonesia’s Batik Air and Malaysia’s Malindo Air. Malindo expanded its fleet by a staggering 15 aircraft, for a total of 42, making it one of the fastest-growing airlines in the world. Batik expanded its fleet by eight aircraft in 2016, for a total of 41.
The rate of expansion slowed at all three of Lion Group’s low cost airlines – Lion Air, Thai Lion Air and the turboprop operator Wings Air. The fleet at the main Lion Air brand only expanded by three aircraft, while Wings added four turboprops. The group’s JV in Thailand added six aircraft, which was fewer aircraft than initially planned.
