Airbus A350-1000ULR set 24-hour nonstop Australia-France record. Qantas ordered 12 for Project Sunrise, targeting Sydney-London and New York by 2027.
The aviation industry just witnessed a milestone that brings the world closer together. The Airbus A350-1000ULR, an ultra-long-range variant of the popular A350 family, completed a record-breaking nonstop flight between Australia and France that lasted more than 24 hours. This achievement not only demonstrates the aircraft’s extraordinary range but also paves the way for Qantas’s ambitious Project Sunrise—nonstop flights from Sydney to destinations like New York and London by 2027. In this article, we delve into the test flight details, the engineering behind the aircraft, and what this means for the future of long-distance air travel.
The A350-1000ULR took off from Australia bound for France and stayed airborne for over 24 hours, setting a new benchmark for commercial jetliners. This wasn’t the aircraft’s first ultra-long test flight. Earlier, it flew from Toulouse, France, to Melbourne, Australia, in 19 hours 13 minutes as part of initial testing. Both flights, reported by Ars Technica, validate the aircraft’s capability to operate on the world’s longest airline routes without refueling.
For Qantas, which has ordered 12 of these jets, this is critical validation for Project Sunrise—a plan to connect Sydney to London and New York nonstop. Those flights cover roughly 16,000 to 17,000 kilometers and will require over 19 hours in the air, pushing the limits of crew endurance and passenger comfort.
The A350-1000ULR (Ultra Long Range) builds on the proven A350-1000 platform with key modifications to extend its range beyond the standard 8,000 nautical miles (14,800 km). Airbus engineers focused on several enhancements:
While Airbus has not published official range figures, analysts estimate the A350-1000ULR can exceed 9,500 nautical miles (17,600 km), putting destinations like London–Perth, New York–Singapore, and Sydney–Paris within nonstop reach.
Qantas has long been a pioneer in ultra-long-haul travel. After introducing “Kangaroo Route” flights from Australia to Europe via a stopover, Project Sunrise aims to eliminate that stop completely. The airline selected the A350-1000ULR through a competitive process that also considered the Boeing 777X.
The 12 aircraft on order will be configured with approximately 250 seats—far fewer than the typical 350-seat layout—to maximize passenger comfort. According to Qantas, the cabins will include premium economy, business suites with direct aisle access, and a dedicated wellbeing zone for stretching during the marathon flights.
First ticket sales are expected to begin in 2027, with initial routes from Sydney to London and New York. The recent record flight from Australia to France, which closely mirrors the eventual commercial routes, confirms the A350-1000ULR can handle the extreme conditions of the Pacific-Atlantic pathway, including strong headwinds and limited alternate airports.
Project Sunrise is more than a product launch; it represents a reinvention of long-distance travel. Qantas has invested heavily in crew programs, including specially designed rest areas and adjusted work schedules, to ensure safety and service quality on flights that can last longer than a full day.
Ultra-long-haul flights are not just engineering feats; they require careful economic analysis. The cost of operating such flights is higher than conventional routes due to several factors:
Despite these challenges, airlines can command premium fares on nonstop services. Business travelers, in particular, value the time savings and convenience of a one-stop flight. Qantas expects the premium cabins to generate enough revenue to make the route profitable.
Moreover, sustainability is a growing concern. Airbus and Qantas are exploring sustainable aviation fuels (SAF) to reduce lifecycle carbon emissions. The A350-1000ULR is certified for up to 50% SAF blend, and Project Sunrise could serve as a catalyst for wider SAF adoption.
The successful A350-1000ULR test flight signals that ultra-long-haul is ready for prime time. Other airlines are likely to follow suit. Possible future routes include:
Aircraft manufacturers continue to push the envelope. Boeing is developing the 777-9, which promises similar range, and future designs may incorporate even more efficient aerodynamics and propulsion. However, the A350-1000ULR currently stands as the benchmark for long-range commercial operations.
The trend toward ultra-long-haul flights is rising, with market projections showing increased demand for point-to-point connections that bypass traditional hubs. This shift could transform international travel, reducing journey times and streamlining airport congestion.
Yet there are caveats. The carbon footprint of ultra-long flights is significant, and regulators may impose stricter environmental constraints. The industry will need to balance connectivity with climate goals, perhaps through carbon offsets or innovations like hydrogen-electric flight for shorter sectors.
The Airbus A350-1000ULR’s record-breaking nonstop flight from Australia to France is more than a headline—it is a preview of the future of air travel. With over 24 hours in the air, the aircraft proved its endurance for the world’s longest routes. Qantas’s commitment to 12 of these aircraft underscores the demand for nonstop connectivity from Sydney to destinations like New York, London, and beyond.
For technology professionals and aviation enthusiasts, this development exemplifies the convergence of advanced materials, aerodynamics, and operational ingenuity. As final certification and commercial entry approach, the A350-1000ULR will reshape global travel maps, bringing cities on opposite sides of the planet closer together without a single layover.
The next few years promise to be transformative. With ticket sales slated for 2027 and a growing fleet of ultra-long-range aircraft, the era of 20-hour nonstop flights is upon us. Whether for business or leisure, travelers can look forward to a future where the world is more connected than ever.
The A350-1000ULR (Ultra Long Range) is a specially modified version of the Airbus A350-1000 designed for nonstop flights exceeding 20 hours. It features increased fuel capacity, structural weight reduction using composites, and engine optimizations to achieve extreme range, such as the record-breaking 24-hour flight from Australia to France.
Project Sunrise is Qantas's plan to operate nonstop flights from Sydney to London and New York, covering 16,000 to 17,000 kilometers in over 19 hours. Qantas has ordered 12 A350-1000ULR aircraft to serve these routes, with a target launch by 2027, eliminating the need for layovers and reducing total travel time significantly.
Engineers added extra fuel tanks, reduced empty weight with carbon-fiber-reinforced plastic, optimized the Rolls-Royce Trent XWB-97 engines for better fuel burn, and strengthened landing gear to handle higher takeoff weights. These changes allow the aircraft to carry enough fuel for flights of 20 hours or more without refueling.
Key challenges include managing crew fatigue with extended duty periods, ensuring passenger comfort during long hours onboard, and maintaining fuel efficiency over extreme distances. Airlines must also meet regulatory requirements for crew rest and design cabins with specialized lighting, dining, and exercise options to mitigate jet lag.
While both can fly ultra-long routes, the A350-1000ULR offers a more modern composite airframe and advanced Rolls-Royce engines, providing better fuel efficiency and lower emissions. The 777-200LR has a slightly shorter range but has been in service longer. The A350-1000ULR is specifically tailored for Qantas's longer Project Sunrise routes.
