The first production Boeing 777-9 destined for launch customer Lufthansa successfully completed its maiden flight from Paine Field in Everett, Washington, on May 7, marking one of the most important milestones to date for the long-delayed widebody programme. The aircraft, which carries the customer designation WH128 and registration N20080, departed shortly after 20:40 UTC and returned to Everett roughly three hours later after climbing to 39,000 feet during the initial test profile.
Unlike earlier flight-test aircraft used in the certification campaign, the WH128 was rolled out with a full Lufthansa interior already installed, including the carrier's brand-new Allegris cabin product across First, Business, Premium Economy and Economy. The flight was conducted by Boeing test pilots Ted Grady and Jake Miller, and the aircraft is now expected to enter the customer-facing portion of the test programme in the weeks ahead.
Lufthansa remains the formal launch customer for the 777-9 and currently holds firm orders for 20 aircraft, alongside additional commitments for the smaller 777-8 freighter variant. The German flag carrier first signed up for the type back in 2014 as part of a long-term widebody renewal plan that has been forced through repeated revisions as the 777X programme slipped from its original 2020 entry-into-service target.
Boeing has consistently said it is targeting type certification in 2026, with first deliveries to Lufthansa expected in 2027. The certification work has been complicated by issues with the GE9X engines, the folding wingtip mechanism and updated regulatory expectations following the 737 MAX and 787 oversight reviews, which have made the campaign substantially longer than originally planned.
For Lufthansa, the maiden flight is a significant signal that the 777-9 is finally moving into the home stretch. The carrier has already begun preparing crew training and ground-handling infrastructure across its Frankfurt and Munich hubs, and plans to deploy the type initially on long-haul flagship routes to North America and Asia. Once delivered, the 777-9 will sit at the top of the Lufthansa fleet alongside the airline's existing Airbus A350-900 and Boeing 747-8I aircraft.
