On 2 June 2026, a bare green-primer jet lifted off from Toulouse, climbed past 41,000 feet, and flew for three hours and forty-three minutes before coming home. It wore no airline colours yet — just a working title stencilled down the fuselage: “First A350-1000ULR for Qantas. Project Sunrise.”

That unglamorous test hop was the quiet beginning of something the aviation world has chased for a century: a direct, nonstop flight between Australia’s east coast and the other side of the planet. And a fortnight later, Qantas finally put a date and a destination on it. The world’s longest scheduled passenger flight — Sydney to London, nonstop — begins in October 2027.

The Jet Built to Beat Distance

The aircraft that makes it possible is the Airbus A350-1000ULR, the newest and longest-legged member of the A350 family. On paper it is a fairly modest modification: engineers built an additional rear centre fuel tank into the airframe, adding roughly 1,000 nautical miles of range. In practice, those extra kilometres are the difference between “almost” and “nonstop.”

The ULR can stay airborne for up to 22 hours and cover close to 10,000 nautical miles without refuelling, making it the longest-range airliner ever built. Airbus is even certifying a new galley air-cooling system designed specifically for flights long enough that the food has to survive the better part of a day aloft. Qantas has ordered twelve of them.

The Kangaroo Route’s Final Form

For most of the last century, getting from Australia to Britain meant the famous “Kangaroo Route” — a series of hops, each one a chance to refuel and stretch your legs. Project Sunrise erases the stops entirely. From October 2027, Qantas will fly Sydney to London nonstop, the first time the route has ever been flown without a break from the country’s east coast. Sydney to New York is next in line.

For an airline whose whole identity is built around conquering distance, it is a milestone with real emotional weight.

Qantas is no stranger to ultra-long-haul. It already flies Perth to London nonstop with the Boeing 787 — a route that, until now, held the title of the airline’s longest. The A350-1000ULR simply takes the idea to its logical extreme.

Twenty-Two Hours in a Tube

The engineering is only half the challenge. Keeping passengers sane and healthy for the better part of a day is the other half. The ULR’s cabins will seat just 238 people across four classes — a deliberately low number for an aircraft this size — with lighting, meal timing and cabin pressure all tuned to fight jet lag rather than simply endure it.

The first jet to actually wear Qantas colours is due for delivery in April 2027, with tickets going on sale in February that year. After more than a decade of studies, simulator marathons and false starts, the last great gap in the global route map is about to close — one very long flight at a time.
