Sydney to London Without Stopping: What 22 Hours on the A350-1000ULR Will Actually Feel Like

A reader's guide to Qantas's Project Sunrise jet

It's 3:00 AM. You're slumped on a terminal bench in Singapore, your ankles have swollen to the size of grapefruits, and the only thing open is a coffee kiosk that's out of oat milk. You still have a seven-hour flight ahead of you.

That's the standard way to get from Australia's east coast to Europe. For decades, it's been simply how things worked.

Qantas wants to retire that experience. Its answer is the Airbus A350-1000ULR, a jet built to fly for up to 22 hours without touching down. It sounds like a punishment. It might turn out to be a relief. Let's look at what's changed, what's on board, and whether you'd actually want to sit through it.

Why It's Called Project Sunrise (and Why the Name Fits)

Qantas kicked off Project Sunrise in 2017 with a blunt challenge to aircraft makers: build something that can fly from Australia's east coast to London or New York in one hop.

The name comes from a wartime story. After Singapore fell, Qantas flew Catalina flying boats between Western Australia and Sri Lanka to keep a lifeline open to Britain. Those flights carried just three passengers and about 70 kilograms of mail. They lasted up to 33 hours, long enough that the crew watched the sun come up twice.

Picture that: noisy, cold, cramped, and nobody sure the plane would make it. Now compare it with a pressurised, quiet cabin and a seat that reclines. Same airline, same spirit of stubbornness, very different Tuesday.

How Do You Make a Twin-Engine Jet Fly for 22 Hours?

You can't just strap a bigger fuel tank on and hope. Every extra litre of fuel is weight, and weight needs more fuel to carry it. Aviation engineers call this the tyranny of the fuel spiral, and it's what makes ultra-long-haul so hard.

Airbus attacked the problem from several angles.

The Rear Centre Tank: More Fuel, Smarter Placement

The headline change is a new Rear Centre Tank built into the fuselage. It adds 20,000 litres of capacity and stretches range by about 1,000 nautical miles over a regular A350-1000. Just as important, it gives pilots a safety buffer. After 22 hours, you don't want to discover that a diversion or a holding pattern has eaten your reserves.

Heavier Take-Off Limits, Stronger Engines

All that fuel has to leave the ground. Airbus raised the maximum take-off weight, and the jet relies on Rolls-Royce Trent XWB-97 engines to haul it into the sky. Think of a hiker with a heavy pack: you need stronger legs, and you need to know exactly how much you can carry.

Shaving Kilos Where You'd Never Look

Here's my favourite detail. The ULR debuts a new galley cooling system for food and drink refrigeration. It's lighter and more efficient, and it trims roughly 300 kilograms. That's the weight of a grand piano's worth of savings from fridges. Airbus plans to roll it out across the wider A350 family.

What the Test Flights Have Shown

The first ULR flew in Toulouse in early June 2026, and the testing since has been ambitious. The jet landed in Melbourne after a 19-hour journey from Toulouse, the first time the type touched down in Australia. Then came the real endurance run: a non-stop flight from Melbourne back to Toulouse lasting 24 hours and 24 minutes and covering 23,075 km.

That's longer than the planned commercial flights, which is exactly the point. Engineers want to know how every pump, gauge, and fuel transfer behaves when the clock runs past what passengers will ever experience.

The Cabin: Built for Humans, Not Just Fuel Math

Let's be honest. Twenty-two hours in a seat sounds miserable. If eight hours across the Atlantic leaves you stiff, a full day in the air probably feels like a dare.

Qantas knows it, so the cabin has been designed around that fear.

Fewer Seats, More Room

A typical A350-1000 carries 300 to 350 passengers. Qantas caps this one at 238. Fewer people means less weight, which saves fuel, and it means each person gets more space. Here's the split:

•         6 First suites: private, enclosed, built for sleeping

•         52 Business suites: lie-flat with direct aisle access

•         40 Premium Economy seats: extra legroom and recline

•         140 Economy seats: a roomier 33-inch pitch than most long-haul cabins

The Wellbeing Zone

This is the feature people keep talking about. Between Premium Economy and Economy sits an open area with stretch handles, guided on-screen exercise programs, and a hydration station with refreshments. You can walk over, loosen your hips, drink some water, and head back.

It won't turn the flight into a spa day. But for anyone who's ever done laps of the aisle at hour nine, a dedicated space to move without apologising to a sleeping stranger is a big deal.

Standard A350-1000 vs. A350-1000ULR

Feature	Standard A350-1000	A350-1000ULR
Main job	High-capacity long-haul	Non-stop ultra-long-haul
Fuel setup	Standard wing and centre tanks	Adds 20,000L Rear Centre Tank
Range	Baseline intercontinental	About 1,000 nm more
Longest flights	Roughly 12 to 16 hours	Up to 22 hours
Seats	300 to 350+	238
Passenger extras	Standard cabin	Wellbeing Zone, 33" Economy pitch

When Can You Actually Book It?

The timeline has shifted a little. Delivery was originally pencilled in for late 2026, but Airbus and Qantas confirmed a postponement to April 2027 due to supply chain issues. Qantas has since announced that London will be the first Project Sunrise destination, with Sydney departures tentatively scheduled for October 2027. A Sydney–New York service is also planned.

So if you're eyeing a ticket, you've got some waiting to do. Qantas has ordered 12 of these jets for Project Sunrise, plus a separate batch of standard A350-1000s for the rest of its international network.

The ULR is also the fourth passenger variant in the A350 family, and the lightweight carbon-composite design delivers around 25% lower fuel burn and emissions than the previous generation of aircraft it replaces.

Practical Tips for Surviving a 22-Hour Non-Stop

Nobody's going to hand you a medal for sitting still. A few habits will make the difference between landing human and landing wrecked.

1.       Move on a schedule. Don't wait until you feel stiff. Set a reminder every couple of hours and head to the Wellbeing Zone.

2.       Switch clocks at the gate. Set your watch to your destination time the moment you board, and try to sleep when it's night there.

3.       Drink water like it's your job. Cabin air is dry. Hydrate steadily, and go easy on alcohol.

4.       Use the extra pitch. In Economy, 33 inches makes resting, reading, or typing noticeably easier.

5.       Do the maths on layovers. You're skipping a second security line, a transfer sprint, and that 3:00 AM bench. That time counts.

Key Takeaways

•         The A350-1000ULR adds a 20,000-litre rear tank, uprated take-off weight, and lighter galley systems to fly up to 22 hours non-stop.

•         Qantas limits the cabin to 238 seats, trading capacity for comfort.

•         The Wellbeing Zone is a genuine design answer to the question, "How do I survive this?"

•         Test flights of 19 and 24 hours suggest the jet is being pushed well beyond planned service.

•         Expect the first delivery in April 2027 and Sydney–London service from October 2027.

Wrap-Up: A Long Flight That Might Feel Shorter

Ultra-long-haul used to mean a compromise. You either stopped somewhere and lost hours, or you pushed through on a crowded jet and lost your sanity. The A350-1000ULR tries to split the difference with smart engineering, a smaller cabin, and a space built specifically for moving around.

Will it be easy? No. But skipping the middle-of-the-night transfer, the lounge hunt, and the second boarding queue is tempting, and plenty of travellers will take that deal.

So, what's your call? Would you sit through 22 hours straight to land in London without a stop, or do you still prefer breaking the journey in the middle? Tell me in the comments. I'd love to hear whether the Wellbeing Zone sounds like a clever fix or a very long stretch class.
