Why The Flagship Of The World’s Elite Airlines Is No Longer In Production

The End of an Era: Boeing 777-300ER Production Concludes
In 2004, the aviation industry witnessed a significant transformation with the introduction of the Boeing 777-300ER, an extended-range variant of the 777 family. First operated commercially by Air France, Boeing hailed the 777-300ER as "the most technologically advanced airplane in the industry" at the time. It surpassed its predecessors—the 777-200 and 777-200ER—in both comfort and operational range. Equipped with updated systems and powered by the General Electric GE90-115B turbofan, the most powerful commercial jet engine available then, the 777-300ER quickly became a favorite among airlines for long-haul routes. Its combination of extended range and fuel efficiency allowed carriers to maximize profitability through operational efficiency and high passenger capacity. The aircraft remains a staple in many fleets worldwide, including China Eastern Airlines, which utilized it to inaugurate the world’s longest direct one-stop flight.
Production Milestones and Legacy
The production of the Boeing 777-300ER officially ended in 2024, marking the conclusion of nearly two decades of manufacturing the world’s best-selling widebody aircraft. According to Boeing, a total of 833 units of the 777-300ER were delivered, accounting for a substantial portion of the 1,781 aircraft in the entire 777 family, which has seen 2,457 orders to date. These figures underscore the 777-300ER’s status as the most popular variant within the best-selling widebody airliner family in aviation history.
The final 777-300ER was delivered in December 2024 to Altavair LP, an aircraft finance, leasing, and management company specializing in the acquisition, leasing, repurposing, and sale of commercial jets and engines. Since its establishment in 2003, Altavair has completed over $12 billion in commercial aircraft lease transactions and manages a portfolio exceeding 300 Boeing and Airbus aircraft.
Boeing’s gradual reduction in 777-300ER production coincided with the development and refinement of the next-generation 777X. Delivery numbers had steadily declined in recent years, with only 19 aircraft delivered in 2019, dropping to a single unit in 2024. The last 777-300ER delivered before the final unit was in 2022, when three aircraft were handed over to Thai Airways.
The Final Aircraft’s Journey
The last 777-300ER produced in 2024 was initially ordered by China Southern Airlines. However, due to disruptions caused by the COVID-19 pandemic, the order was canceled, and the aircraft remained in storage for nearly five years. Altavair subsequently acquired the plane and leased it to Ethiopian Airlines in 2024, extending the operational life of this iconic aircraft as Boeing transitions fully into the era of the 777X.
