Boeing has launched the 777X program at the 2013 Dubai Airshow with a record-breaking number of customer orders and commitments for the newest member of its twin-aisle product family.

Agreements for 259 airplanes from four customers across Europe and the Middle East provide a strong foundation to support development and production of the airplane.

Representing the largest product launch in commercial jetliner history by dollar value, 777X orders and commitments include Lufthansa with 34 airplanes; Etihad Airways with 25; Qatar Airways with 50 and Emirates with 150 airplanes.

The combined value of the agreements is more than $95 billion at list prices.

“We are proud to partner with each of these esteemed airlines to launch the 777X – the largest and most-efficient twin-engine jetliner in the world,” said Boeing Commercial Airplanes president and chief executive Ray Conner.

“Its ground-breaking engine technologies and all-new composite wing will deliver unsurpassed value and growth potential to our customers.”

The 777X builds on the passenger-preferred and market-leading 777, which today commands 55 per cent of market share in its category in terms of backlog, and 71 percent of the in-service fleet worldwide.

The 777X family includes the 777-8X and the 777-9X, both designed to respond to market needs and customer preferences.

The 777X builds on the best-in-class dispatch reliability from today’s 777, as well as offering more market coverage and revenue capability that surpasses the competition. The 777-8X competes directly with the A350-1000, while the 777-9X is in a class by itself.

Opening new growth opportunities for airlines, the 777-9X offers seating for more than 400 passengers, depending on an airline’s configuration choices.

With a range of more than 8,200 nautical miles, the airplane will have the lowest operating cost per seat of any commercial airplane.

The second member of the family, the 777-8X, will be the most flexible jet in the world.

The airplane will seat 350 passengers and offer an incredible range capability of more than 9,300 nautical miles.

In addition, the airplane will have unmatched takeoff and payload capability compared to the competition.

“The airplane will build on the market-leading 777 and will provide superior operating economics,” said Conner.

“The airplane will be 12 per cent more fuel efficient than any competing airplane, necessary in today’s competitive environment.”
