Boeing has welcomed Lufthansa’s selection of the 777-9X for its future long-haul fleet.

The launch of the 777X family is targeted for later this year and entry into service around the end of the decade.

Advanced technology including a new composite wing, all-new engines and superior aerodynamics will result in the incredible fuel efficiency promised by the 777X family.

The 777-9X, with around 400 seats, will be the largest and most efficient twin-engine commercial jet in the world with the lowest operating cost per seat of any commercial airplane and no competitor in its market segment.

“We are focused on developing and delivering a superior airplane that ensures the 777 remains the unequivocal long-haul leader,” said John Wojick, senior vice president of global sales, Boeing Commercial Airplanes.

“With its new engines and an all-new composite wing design, the 777X will be the largest and most-efficient twin engine jet in the world with 20 per cent lower fuel consumption and 15 percent lower operating costs than today’s 777.

“Boeing is delighted that Lufthansa is continuing its longstanding partnership with Boeing by selecting the 777X for its future fleet development.”

Earlier this year, the Lufthansa Group ordered six 777-300ERs for the fleet of Swiss International Airlines.

Boeing will deliver the first of Lufthansa Cargo’s five new 777 Freighters later this year.

Lufthansa today operates 93 Boeing airplanes within its group fleets.
