en.Wedoany.com Report on Mar 23rd, The Boeing 777-300ER entered commercial service in 2004, introduced by Air France, and was equipped with General Electric GE90-115B turbofan engines. It gained popularity on long-haul routes for its extended range and fuel efficiency. This aircraft model continues to be used by numerous airlines worldwide. For example, China Eastern Airlines once operated it on long-haul non-stop flights.

According to Aerospace Global News, only one Boeing 777-300ER was produced in 2024 and delivered in December to the aircraft finance company Altavair LP, marking the end of nearly two decades of production for this popular wide-body jet. Boeing data shows that 833 777-300ERs were delivered, accounting for a significant portion of total 777 family deliveries, making it the most popular variant of the series.

Boeing has slowed 777-300ER production to prioritize testing and refining the new-generation 777X models. As reported by Air Data News, prior to the final delivery, the last deliveries were three aircraft to Thai Airways in 2022. The 777-300ER received by Altavair was originally ordered by China Southern Airlines, stored for nearly five years due to the pandemic, and later leased to Ethiopian Airlines in 2024.

The 777-300ER has a range of up to 7,370 nautical miles, benefiting from its efficient design and GE90 engines, which were once the most powerful commercial jet engines before being surpassed by the General Electric GE9X in 2019. The GE9X is expected to be delivered with the 777X, offering higher fuel efficiency.

Due to its high passenger capacity and operational efficiency, the 777-300ER became a workhorse for global airlines such as Emirates and Qatar Airways, with Emirates currently operating 119. Although the 777X program has faced delays and challenges, Boeing has shifted its focus to this model as a replacement for the 777-300ER.

A mechanics' strike in 2024 may have impacted Boeing's wide-body production line, with workers demanding pay raises and pension restoration, according to Reuters. Stephanie Pope, CEO of Boeing Commercial Airplanes, announced that production resumed in December 2024, with the final 777-300ER delivered the same month.

Despite the end of 777-300ER production, the aircraft will remain in service on long-haul flights for many years to come. Growing passenger demand means airlines will continue to rely on its value. The base 777 model has been in service since 1995, and the 777-300ER's practicality ensures passengers will still have opportunities to fly on it.
