data sheet. This raised its range from . A further MTOW increase by , to a total of is under study to be available from 2020 and could be a response to Qantas' Project Sunrise. Initial speculation suggested that the variant might be marketed as the A350-1000ULR. However, the -1000 is not expected to share the -900ULR's larger fuel tanks and other fuel system modifications, and Airbus has stopped short of describing the largest MTOW variant as a ULR model, despite the range. In November 2019, maximum accommodation increased to 480 seats from 440 through the installation of new "Type-A+" exits, with a dual-lane evacuation slide. On 17 December 2021, French Bee took delivery of the first A350-1000 in this 480-seat configuration, leased by Air Lease Corporation and to be operated by from Paris to Reunion Island, with 40 premium and 440 economy seats. In December 2019, Qantas tentatively chose the A350-1000 to operate their Project Sunrise routes, before a final decision in March 2020 for up to 12 aircraft. After a delay due to the COVID-19 pandemic, the decision was confirmed on 2 May 2022, when Qantas placed a formal order for 12 Airbus A350-1000 aircraft for Project Sunrise flights to start in 2025. The aircraft will be configured with 238 seats in four classes. A350F An A350-900 freighter was first mentioned in 2007, offering a similar capacity to the MD-11F with a range of 9,250 km (5,000 nmi), to be developed after the passenger version. In early 2020, Airbus was proposing an A350F before a potential launch. The proposed freighter would be slightly longer than the A350-900 and Airbus would need 50 orders to launch the $2–3 billion programme. In July 2021, the Airbus board approved the freighter development. It is based on the -1000 version for a payload over 90 tonnes, and entry into service is targeted for 2025. The A350F would keep the A350-1000 319 t MTOW, shortened but still longer than the Boeing 777F for 10% larger freight volume at compared to for the 777F, similar to the Boeing 747-8F. With a maindeck cargo door behind the wing and reinforced main deck aluminum floor beams, its payload is higher than the of the 777F, while its empty weight is lighter than the A350-1000, lighter than the 777F. At the November 2021 Dubai Air Show, US lessor Air Lease Corporation became the launch customer with an
