Estimate from the variant's published specs, 0-5; scores are only comparable within one criteria year. 777-9 (GE9X, MTOW 775,000 lb, 426 typical two-class seats). Range 7,285 nmi (13,500 km) = 4.5 (interpolated 6,500 = 4, 8,000 = 5). Capacity 426 typical two-class seats = 5.0. Speed null: the 777-9's typical cruise Mach was not stated in any page opened (the first-flight pages give only test-flight speeds). Efficiency null: Boeing's percentage claims are not a published fuel burn. Runway null: no airport-planning document for the 777-9 read. Only Mach .84 seen is a first-flight test point. Comfort null: reviews so far are pilot reports of the test aircraft, none of the cabin. boeing.mediaroom.com
It really was a pretty smooth flight. You could tell that the team had the airplane in excellent condition
According to Boeing, an engineering pilot on board the flight said the airplane performed “beautifully.”
Van Chaney, one of the pilots who flew the test flight, was thrilled with how the plane handled. “It was awesome,” he said.

波音只说是 2027 年。据汉莎航空培训公司称,启动客户汉莎航空的交付“目前定于 2027 年年中”,因此该时间点定在年中。
Boeing's 777X page lists the 777-9 at 375-450 seats, "Up to 8,000 nmi", 76.7 m long with a 71.8 m wingspan folding to 64.8 m, and claims "20% lower fuel use and emissions".
Wikipedia's Boeing[2] 777X article describes GE9X engines, "composite wings with folding wingtips", the January 25, 2020 first flight and 110,000 lbf thrust per engine.
