Qantas A350-1000ULR sets 12,503nm Guinness record on Toulouse test flight

Airbus's A350-1000ULR built for Qantas has flown 12,503 nautical miles — 23,155 kilometres — non-stop from Melbourne to Toulouse, setting a Guinness World Record for the longest flight by distance on a commercial airliner. The aircraft spent 24 hours and 24 minutes in the air. It is the test article for Project Sunrise, the programme that will put Sydney–London non-stops into service from October 2027.

What exactly happened?

The record flight departed Melbourne International Airport at 5:27pm local time on Monday, 27 July, and landed at Airbus's main factory in Toulouse at 9:51am local time on Tuesday, 28 July. Thirteen people rode along: three Airbus flight test pilots, two Qantas pilots, five Airbus flight test engineers, two Airbus design engineers and one representative of the International Aeronautical Federation.

The Federation and teams at Flightradar24 independently verified the aircraft data before Guinness handed down the title. The crew, true to the programme's name, chased the sun through two sunsets, two sunrises, three continents and two oceans.

What does the record prove?

Records are marketing until the engineering backs them. Here it does, at least in part. The flight doubled as the latest in a series of test campaigns, monitoring how the airframe and its additional 20,000-litre centralised fuel tank perform on missions at the very edge of commercial range.

Lars Wagner, CEO of commercial aircraft at Airbus, said the achievement "reflects the pioneering and innovative spirit" behind the custom ultra-long-range jet, which can connect Australia to essentially any city on the planet. "In responding to the challenge laid down by Qantas, our teams came together to extend the range of the A350-1000 in an efficient and economically viable way to undertake the world's longest ever commercial flights," he said.

His verdict on the flight itself was less restrained: "Flying 12,503 nautical miles non-stop, we have fully proven the aircraft's capability to fulfil its mission. And the world record was the icing on the cake!" A cake reference from an OEM chief executive is, by industry standards, practically giddiness.

How does this fit Project Sunrise's timeline?

Qantas expects its first A350-1000ULR delivery in April 2027, with the first Sydney–London non-stops taking off from October 2027. The flagship QF1 and QF2 flight numbers will transfer to the new non-stop services at launch.

The numbers carry weight. QF1 and QF2 currently serve Sydney–London via Singapore; the one-stop routing loses its premium designation to the non-stop, which Qantas says saves passengers up to four hours against the existing service.

The history is doing quiet work here, as Qantas well knows. "The Kangaroo Route first began flying from Sydney–London in 1947, when the journey took four days and seven stops," the carrier said in a press release. "For almost 80 years, generations of Qantas aircraft, from the Lockheed Constellation to the Boeing 747 and Airbus A380, have brought Sydney and London closer together." Four days and seven stops in 1947; 24 hours and no stops, potentially, by 2027.

The renumbering cascades down the network. The Sydney–London via Singapore service switches to QF5 and QF6. The existing seasonal Perth–Rome route, which currently holds those designations, moves to QF105 and QF106.

What remains unproven?

The record flight demonstrates the airframe's range and fuel-system performance. It does not yet demonstrate the economics of filling 238-odd seats on a 20-hour sector, day after day, at fares passengers will pay. That test begins in earnest with the April 2027 delivery.
