Singapore Airlines’ First Boeing 777-9 Takes Flight

Boeing has conducted the first test flight of a Boeing 777-9 destined for Singapore Airlines, marking a key milestone for the long-delayed program. The test, which took place on August 5 at Boeing’s Everett facility near Seattle, lasted just under three hours and represents the fifth flight-test aircraft in the 777X program. Unlike previous test aircraft, this jet will eventually be delivered to a commercial airline, though it currently remains in an all-white livery.

The successful flight signals renewed momentum for the 777X certification process. The U.S. Federal Aviation Administration has authorized Boeing to move forward with the next phase of testing, opening the door for potential entry into service by mid-2026. Initially scheduled to debut in 2019, the 777X program has faced a series of setbacks including engine issues, design challenges, and supply chain disruptions related to the COVID-19 pandemic.

Singapore Airlines, which ordered 31 of the 777-9 variant, had originally expected deliveries to begin in 2021. However, repeated delays have forced the carrier to postpone the introduction of new First and Business Class cabins, which were initially designed to launch with the aircraft. As a workaround, Singapore Airlines will now retrofit long-haul Airbus A350s with its next-generation cabin products, with the debut planned for 2026.

The 777X family, comprising the 777-8 and 777-9, has accumulated more than 500 orders but none have yet been delivered. Emirates, the largest customer with 205 aircraft on order, plans to use the 777X to replace its Airbus A380s. Other major customers include Qatar Airways, Lufthansa, and Cathay Pacific. The latter recently confirmed a $8.1 billion order for 14 additional 777-9s, bringing its total commitment to 35 aircraft, with deliveries expected by 2034.

While the Singapore Airlines jet that just flew may not be the first delivered, it reflects the airline’s longstanding history of participating in manufacturer test programs. In 2018, Singapore Airlines was also the launch customer for the Boeing 787-10, taking delivery of the first unit after it was used in testing.

As global airlines continue to restructure long-haul fleets and modernize premium cabins, further delays in the 777X program could impact future fleet strategies. For now, Boeing’s resumption of flight testing brings cautious optimism that the world’s largest twin-engine aircraft is finally moving toward commercial service.
