TOULOUSE, France — Qantas Airways is placing a major wager on science to make the world’s longest commercial flights more endurable, revealing detailed plans for nonstop Sydney-to-London service set to begin next October. The Australian airline’s ambitious initiative — dubbed “Project Sunrise” — includes a specially designed wellness area, strategic meal scheduling, extra legroom options, and custom animated cabin lighting.
The carrier also has plans to eventually offer nonstop flights between Sydney and New York, and this week provided in-depth briefings on the science of operating roughly 20-hour journeys as it works to persuade travelers to pay more for skipping a layover.
“It’s a major biological challenge crossing all these time zones — seven to nine for London and 14 to 16 for New York,” said Peter Cistulli, a professor of sleep medicine at the University of Sydney who contributed to the scientific research behind Project Sunrise.
Frequent Australian long-haul travelers surveyed by Reuters said their top concerns when considering these ultra-long flights were seat comfort, the freedom to move around the cabin, and ticket prices.
Qantas has gone further than those basics, examining every aspect of the passenger experience on the specially modified Airbus A350-1000ULR aircraft since the project began nearly ten years ago. That research has covered everything from nutrition and ergonomics to movement patterns — and most critically, lighting, which plays a key role in regulating the human body clock.
By carefully scheduling meals — including avoiding food immediately after takeoff — and using lighting to establish a “protective sleep window,” passengers in tests showed sharper alertness compared to those on a conventional flight service, Cistulli noted.
Cabin designer David Caon said he was tasked with approaching the interior as both a health and scientific challenge, not just a visual one.
“When you have a passenger for essentially a whole day, it really does drive a whole set of new decisions,” he said.
Caon explored unconventional concepts during the design process, including exercise bikes and yoga mats. Neither made the final version, but a dedicated wellness zone did — featuring soft, diffused, shimmering light throughout the space.
“I wanted to recreate the sense of lying by the swimming pool,” Caon told reporters.
Throughout the rest of the cabin, custom mood lighting will mimic sunrises and sunsets, gradually shifting from the front of the plane to the back. Programming the 14 distinct lighting “scenarios,” each inspired by Australian landscapes, took several weeks to complete.
All of these features are designed to reduce the strain of flights that could stretch as long as 22 hours on these specially outfitted aircraft.
Beyond passenger comfort, the spacious cabin design also serves a financial purpose — transforming Australia’s geographic isolation into a travel experience competitors cannot easily replicate, with the goal of generating 20% more revenue per flight.
Qantas CEO Vanessa Hudson said the anticipated price premium over one-stop flights is based on results already seen on routes between Perth and Europe. Most industry analysts say the performance of the airline’s 17-hour Perth-to-London service is a promising sign for the Project Sunrise business model.
The plane has been configured with a heavy emphasis on premium seating, as the airline must maximize profit from just 238 passengers due to weight limitations. In some weather conditions, the airline may need to leave certain seats empty to conserve fuel.
A senior airline industry executive noted that other operational risks would include the high cost of emergency diversions given the extreme length of the routes.
Sam Davies, who works in drinks marketing and travels between his home in Paris and Sydney using the existing Perth route, said he would consider the nonstop option.
“There is something wonderful about waking up in Australia and not having to get off anywhere and go through security and kill three hours, so I am all up for it,” he said.
However, Davies added that seat comfort would ultimately be the deciding factor. “I am six-foot-four (193 cm) so the economy seat is too small… I would have to ask for some more details on the seats,” he said.
Qantas confirmed that standard economy seat pitch — the distance between rows — would be 33 inches (84 cm), though some rows would be slightly tighter at 32 inches, with that information disclosed at the time of booking. A portion of the cabin will be marketed as “Economy Plus,” offering 34 inches of legroom. At the front of the plane, Qantas is joining other carriers in offering enclosed first-class suites with a fixed bed.
Melbourne-based business executive Ian Morden said ultra-long flights don’t discourage him, since he uses the time to work and think. Still, he questioned whether the four hours saved by avoiding a stopover would justify the ticket prices the airline’s financial model requires.
“A slight premium would be justifiable but… I probably wouldn’t choose it for a 20% premium on an already much more expensive business-class flight,” he said.
London-based Nathalie Curtis, who travels frequently for her work in the international cultural sector, said she would book the flight if it delivered on the airline’s promises — though she raised concerns about how quickly cabin conditions can deteriorate on very long flights.
“If it allows you to move around, reduce jet lag with lighting adjustment and is hygienic and saves… four hours then I would go for it and pay a 20% premium,” she said.
Mark Levine, an Australian strategic adviser based in New York, said nonstop flights from Sydney would eliminate the logistical headaches that come with living across multiple continents.
“The distance doesn’t change but the journey feels a little smaller,” he said.
