The first Boeing 777X built for the German flag carrier Lufthansa has successfully conducted its initial test flight from Everett’s Paine Field. This milestone represents a pivotal advancement for the widebody aircraft program, which is currently running nearly seven years behind its original debut schedule.
Flight Technical Details
The aircraft, identified by Manufacturer Serial Number (MSN) 1781, registration N20080, and designated internally as WH128, took to the skies for its maiden voyage this Thursday. It successfully concluded its test profile by landing shortly before 17:00.
According to data from the flight-tracking platform FlightRadar24, the “giant of the skies” operated for a duration of three hours, recording the following performance parameters:
- Maximum Altitude Reached: 39,000 feet (FL390).
- Maximum Recorded Speed: 492 knots.
Lufthansa and Long-Haul Fleet Restructuring
Lufthansa was selected as the launch customer when sales for the Boeing 777X first opened. Currently, the operator maintains a firm order for at least 20 units of the type. Consequently, the first serial production model will be delivered directly to the German carrier, which happens to be celebrating a century of commercial operations this year.
Lufthansa’s original plan projected the Boeing 777X’s entry into service for 2020. However, various delays in the aircraft’s certification process significantly pushed back this timeline. To mitigate the impact of these delays, the airline was forced to retain its veteran Boeing 747-400s—with an average age of 26 years—in active service.
The airline’s current planning envisions the retirement of its final eight Boeing 747-400s within a period of one to two years.

Operational Efficiency: Boeing 777-9 vs. the 747 Family
The Boeing 777-9 will have a seating capacity of approximately 426 passengers, effectively matching the capacity of a Boeing 747 while offering significantly lower operating costs.
Next-Generation Powerplant
The aircraft is powered by General Electric GE9X engines, classified as the most powerful in the world, capable of generating a combined thrust of approximately 220,000 pounds. Key features of these engines include:
- Bypass Ratio: Its 10:1 ratio surpasses the 9:1 metric of the GEnx engines used on the Boeing 747-8, optimizing fuel efficiency and notably reducing noise levels.
- Fuel Burn per Seat: It guarantees a 20% to 25% reduction in fuel consumption per seat compared to the Boeing 747-400, while simultaneously offering superior range.
Optimized Aerodynamic and Cargo Design
- Folding Wingtips: This iconic mobile system allows for maximum aerodynamic performance in flight without compromising compatibility with standard airport gates.
- Increased Belly Cargo Capacity: Thanks to the efficiency of its single-deck configuration and increased compartment dimensions, the 777-9 is expected to carry more belly cargo volume than the passenger version of the Boeing 747-8.
Cabin Experience
Structural improvements in the Boeing 777X allow for a lower cabin altitude—equivalent to 6,000 feet—alongside larger windows and higher ceilings. These elements are designed to reduce passenger fatigue and jet lag.
With the first units scheduled to join the fleet early next year, the successful takeoff of WH128 symbolizes the starting point for the technological renewal of the German carrier’s long-haul fleet.
