Boeing đã lặng lẽ điều chỉnh phạm vi bay được quảng cáo của dòng 777X, mang tới cho các hãng một nâng cấp đáng kể trên giấy tờ trước khi máy bay chính thức vào khai thác thương mại.

The update, spotted on the company's own product pages, expands the operational reach of both passenger variants significantly and could reshape how carriers plan their long-haul networks.

Theo các con số được cập nhật, the 777-9 now offers a range of 8,000 nautical miles, up from the previously advertised 7,285 nautical miles, an increase of 715 nautical miles, or nearly 10%.

The smaller and longer-legged 777-8 saw an equally substantial bump, with its range climbing to 9,500 nautical miles from 8,745 nautical miles – an increase of 755 nautical miles.

The revision was not accompanied by a formal announcement. Instead, the manufacturer quietly updated its published specifications, a change first noticed by those closely monitoring the topic, who confirmed it using the Wayback Machine to show the old figures had been in place as recently as June 17, 2026.

Airlines such as Emirates, Qatar Airways, Lufthansa, and Singapore Airlines have all placed sizable orders for the 777X, and each operator plans to deploy the aircraft on routes that push existing widebodies to their limits.

Đặc biệt, the 777-8 has drawn attention as a potential replacement for the aging 777-200LR on the longest scheduled flights in commercial aviation.

With the updated range of 9,500 nautical miles, it substantially strengthens its case against the Airbus A350-1000ULR, which Airbus has advertised as offering a range of nearly 10,000 nautical miles through an additional rear center tank – narrowing what had been a meaningful gap between the two aircraft.

Chương trình chịu nhiều trì hoãn

777X has faced a difficult path to certification.

Boeing originally targeted service entry in 2020, but engine issues with the GE9X, structural testing setbacks, regulatory scrutiny following the 737 MAX crisis, and pandemic disruptions have all contributed to delays.

First delivery is now targeted for early 2027, with Lufthansa expected to be the launch operator.

Emirates, the program's largest customer, has pressed Boeing repeatedly on timeline commitments and performance guarantees.

Ý nghĩa cạnh tranh

The updated numbers arrive as Airbus continues to build momentum with the A350 family, including securing an order from Emirates in November 2023 – carrier that had resisted the A350 for years.

By extending the range of both 777X variants by more than 700 nautical miles each, Boeing signals that its next-generation widebody's performance continues to improve as flight testing progresses.

Diễn biến tiếp theo

Boeing continues flight testing across multiple 777-9 test airframes, with the 777-8 passenger variant slated to follow later in the certification process.

The 777-8F freighter, with launch customer Qatar Airways, is also in development.

For airlines, travelers, and the wider industry, the specification update is a significant and telling sign that Boeing's next-generation widebody is performing well in testing, and that its capabilities may exceed what the manufacturer was previously willing to advertise.
