Airbus and Qantas are preparing an ultra‑long‑range aircraft that could link cities separated by half the planet in a single, record‑breaking leap.
The ultra-long-haul gamble that could redraw the map
Air travel has always been a compromise between distance, fuel, comfort and cost. In 2026, Airbus plans to tip that balance with a radical version of its A350, designed to stay in the air for about 22 hours without refuelling.
The aircraft, known as the A350‑1000ULR (for Ultra Long Range), is being built primarily for Qantas and its ambitious “Project Sunrise” programme. The goal: nonstop flights from Sydney to London and Sydney to New York, routes that have traditionally demanded at least one stop and a lot of patience.
The first airframe, assembled in Toulouse in late 2025, already has its fuselage, wings, tail and landing gear in place. The engines and flight‑test instruments come next, paving the way for test flights slated for 2026.
For the first time, Australia could be linked nonstop to Europe and the US East Coast on regular, scheduled services.
How Airbus is bending the rules of range
To stay aloft for close to a full day, the A350‑1000ULR needs more than just a bigger fuel bill. It needs a different architecture.
A flying fuel vault
The most striking change sits beneath the rear of the aircraft: an additional fuel tank of around 20,000 litres. This pushes total endurance to roughly 22 hours, adding about 4,000 kilometres of range compared with aircraft Qantas currently uses for its longest routes, such as the Boeing 787‑9 Dreamliner.
That extra reach is what turns Sydney–London, a journey of more than 18,000 kilometres, from a two‑step slog into a single shot. Qantas expects passengers to save around four hours compared with itineraries that require a stop in Asia or the Middle East.
In practice, that means fewer take‑offs and landings, less waiting around at hubs in the middle of the night, and a far more predictable schedule. For business travellers, it also means the chance to sleep, work and arrive in something closer to one piece.

An aircraft that can fly for 22 hours doesn’t just beat a record; it challenges the whole idea of mandatory stopovers on ultra‑long routes.
Chasing a new record in the sky
At the moment, the longest scheduled flight by duration is operated by Xiamen Air between Fuzhou and New York, clocking in at about 19 hours and 20 minutes. That marathon owes some of its length to today’s complex geopolitics: closed airspace over Russia forces a longer Pacific routing.
Project Sunrise is aiming for something more deliberate. The targets are routes that naturally stretch beyond 18,000 kilometres. Depending on winds and weather, flight times between Sydney and London, or Sydney and New York, are expected to hover around the 20‑hour mark and potentially edge higher.
If those numbers hold during trials, the A350‑1000ULR will not just nibble at existing records. It will push the limits of what is considered a viable commercial flight.
Inside a plane built for 20-hour flights
Sitting in a confined seat for nearly a day is no one’s idea of glamour. Qantas and Airbus know that if they want people to book these flights twice, the cabin has to be very different from a standard long‑haul layout.
Fewer seats, more space
Instead of cramming in over 300 passengers, as many A350‑1000s do, Qantas plans to carry about 238 people on its Sunrise aircraft. That reduction allows more room per passenger, bigger premium cabins and new dedicated spaces.
- More generous pitch and width in economy than on typical long‑haul layouts
- Expanded premium economy and business sections aimed at heavy travellers
- A dedicated “wellbeing zone” for stretching and light movement
The wellbeing zone is one of the most unusual features. It will include standing areas, space for guided stretching and simple exercise routines that passengers can follow to keep blood flowing and reduce stiffness and deep vein thrombosis risk.
Lighting and meal timing as a jet lag weapon
Cabin designers worked with sleep and circadian rhythm specialists to shape the onboard experience. Lighting systems will shift colour and intensity through the flight to encourage the body’s internal clock to adjust gradually to the destination time zone.
Meal services are also being rethought. Rather than serving food strictly at traditional times, crews will time higher‑protein or lighter meals to help nudge passengers towards sleep or wakefulness. The aim is to have travellers step off the aircraft less dazed than after two shorter flights separated by a disruptive layover.
For a 20‑hour journey, comfort stops being a luxury feature and becomes a basic requirement for passenger health.
All this extra space and bespoke design has a cost. Qantas has already warned that nonstop Sunrise tickets will likely be about 20% more expensive than comparable itineraries with one stop.
What the 2026 launch could mean for global aviation
If the A350‑1000ULR enters service as planned in 2027, after flight tests beginning in 2026, it will do more than connect Sydney and London. It may nudge airlines, airports and travellers to rethink what long‑haul flying looks like.
New route strategies and shifting hubs
Ultra‑long‑haul aircraft chip away at the logic of traditional hub‑and‑spoke networks. Routes that once required a transfer in Singapore, Dubai or Hong Kong could become nonstop point‑to‑point services.
That does not mean big hubs disappear. They still serve travellers from smaller cities and support dense traffic flows. But a new layer of super‑long flights could appear on route maps, linking far‑flung pairs like Melbourne–Paris or Brisbane–Chicago directly if economics allow.
| Route type | Traditional model | With A350‑1000ULR |
|---|---|---|
| Sydney–London | 1–2 stops via Asia or Middle East | Nonstop, ~20 hours |
| Sydney–New York | Stop on US West Coast or in Asia | Nonstop, ~20 hours |
| Future pairings | Dependent on hubs | Direct point‑to‑point possible |
For travellers in Australia, the shift is stark. Flights to Europe and the US have long been synonymous with overnight layovers and multi‑ticket journeys. Project Sunrise aims to turn those trips into single‑segment flights, changing how Australians plan holidays, family visits and business schedules.
Engines, emissions and the sustainability question
Powering these flights will be Rolls‑Royce Trent XWB engines, a current‑generation turbofan known for relatively high fuel efficiency on wide‑body jets. Even so, ultra‑long‑haul flying remains energy‑intensive.
On a per‑flight basis, these record runs will burn a lot of fuel, and environmental campaigners are already wary. Airlines counter that flying one nonstop leg can emit less per passenger than operating two shorter flights plus the extra take‑offs and landings, which are fuel‑heavy phases. The real climate impact will depend on load factors, aircraft weight management and the use of sustainable aviation fuels.
Qantas has signalled an interest in blending sustainable fuels into these flights where supply allows. Airbus, for its part, is designing the A350 family to be compatible with higher proportions of alternative fuels over time.
What 20 hours in the air does to the body and mind
Spending nearly a full day in a pressurised cabin at altitude poses real physiological and psychological challenges.
Cabin pressurisation on modern composite jets such as the A350 can be set to a lower “cabin altitude” than older models, which can help reduce headaches and dehydration. Improved humidity control also helps. Yet movement remains the biggest factor. On such long flights, medical guidance will heavily stress walking, stretching and hydration.
Airlines may also refine onboard routines as they gather data. For example, crew might encourage short, regular “stretch breaks” in the wellbeing zone, or adapt lighting schedules based on feedback on how rested passengers feel on arrival.
Key terms and scenarios passengers should know
Several technical ideas will show up more often as ultra‑long‑haul becomes mainstream:
- Range: The maximum distance an aircraft can fly without refuelling, influenced by weight, weather and routing.
- Circadian rhythm: The body’s internal clock, which regulates sleep and alertness and gets disrupted during long flights across time zones.
- ULR configuration: A cabin and fuel layout specifically tuned for extended flights instead of maximum seat count.
Imagine a typical traveller from Sydney heading to London. Under the current model, they might depart in the evening, land in Singapore near midnight, wander through duty‑free for two hours, then board another 14‑hour leg. With Project Sunrise, that same person could board once, sleep in longer stretches, walk to a wellbeing zone several times, and land in London with one body clock adjustment instead of two.
On the flip side, anyone who finds long flights mentally draining will need new coping strategies. Entertainment libraries will grow, connectivity will matter more, and simple routines—like splitting the flight into chunks of sleep, work, film and movement—could make the difference between arriving functional or exhausted.
As the first A350‑1000ULR rolls from the hangar towards its 2026 test schedule, one question hangs in the air: are travellers ready to trade the chaos of layovers for the intensity of a single, ultra‑long push through the sky?
