Singapore AirshowBoeing plans to begin delivering improved versions of the 787 Dreamliner in early 2026, after certifying higher maximum take-off weight (MTOW) variants of the 787-9 and 787-10 that allow airlines to fly longer routes or carry more cargo.
MTOW — the maximum weight at which an aircraft is permitted to take off — directly affects how much fuel, payload and range an aircraft can achieve. By increasing this limit, Boeing is enabling the Dreamliner to operate missions that were previously range- or payload-restricted.
Speaking at the Singapore Airshow, Boeing vice president of commercial marketing Darren Hulst said the first 787 aircraft certified at the higher MTOW are already in production and moving through the certification process, with initial deliveries planned for the first half of 2026.
Under the upgrade, the 787-9 will gain an additional 4,540 kg (10,000 lb) of allowable take-off weight, while the larger 787-10 will see an increase of 6,450 kg (14,219 lb). According to Boeing, the change translates into a range extension of about 400 nautical miles (roughly 740 km), or alternatively the ability to carry five to six tonnes of additional cargo.
The increased MTOW does not allow the aircraft to load more fuel physically. Instead, design and structural refinements enable the aircraft to operate at a higher certified weight, improving performance margins and mission flexibility. The shorter 787-8 is not included in the MTOW increase program.

For airlines, the changes expand deployment options
The higher-weight variants allow longer nonstop routes, greater cargo uplift on existing services, or improved economics on freight-heavy sectors where payload is constrained. In some cases, airlines may be able to replace dedicated freighters with passenger aircraft carrying additional belly cargo.
Hulst said airlines will be able to choose between standard and higher-MTOW versions when placing orders, and Boeing expects to produce both configurations in parallel. Several carriers have already expressed interest in the upgraded variants, according to the company.
The MTOW increase is also intended to strengthen the 787’s competitive position against the Airbus A350-900 and A350-1000, particularly on long-haul routes where payload-range performance is a key factor.

The 787 Dreamliner family has accumulated more than 2,000 firm orders, with around 1,200 aircraft in service worldwide. Since entering service in 2011, the type has become a mainstay of long-haul fleets, replacing older four-engine aircraft such as the Airbus A340 and Boeing 747.
Boeing has not disclosed which airline will receive the first higher-MTOW Dreamliner, but confirmed that initial deliveries will begin once certification is completed.
