The Airbus A350-1000ULR (Ultra-Long Range) has officially broken the Guinness World Record for the longest flight by distance by a commercial airliner. The record was based on aircraft data independently validated by the International Aeronautical Federation and flightradar24.

The Airbus-operated flight, with call-sign AIB35LR, departed Melbourne, Australia at 17:27 local time (06:27 UTC) on Monday 27 July and landed in Toulouse, France at 09:51 local time (07:51 UTC) on Tuesday 28 July. The flight covered a distance of 12,503 nautical miles, equivalent to 23,155 kilometres, with a flight time of 24 hours and 24 minutes.

The mission was undertaken as part of the flight test campaign for the A350-1000ULR, which is being developed for Qantas Airways under Project Sunrise. This included a requirement for Airbus to operate one sector with a block time of 23 hours, from push-back at departure to chocks-on at arrival, to simulate the longest commercial operations that will be possible with the aircraft.

After take-off from Melbourne, the aircraft flew over Sydney before heading out over the Pacific on a north-easterly routing towards Los Angeles, crossing the international date line en route. It then flew across the North American continent and over the Atlantic before heading south towards the UK, flying over London and on to Toulouse. As the aircraft crossed three continents and two oceans, the crew witnessed two sunsets and two sunrises.

A total of 13 people were on board the aircraft, including a flight crew of three Airbus flight test pilots, two Qantas pilots, five Airbus flight test engineers, two Airbus design engineers, and a representative of the International Aeronautical Federation.

“This achievement reflects the pioneering and innovative spirit that is part of our DNA at Airbus. 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,” said Lars Wagner, Chief Executive Officer Commercial Aircraft at Airbus. “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!”

“Huge congratulations to all the teams at Airbus who have made this project a reality. And thank you to Qantas for an incredible partnership that has seen us push boundaries together, to Rolls-Royce for its full support and to all our partners who have contributed to this exciting moment in aviation history. Today we can say that the A350 truly is the undisputed Long Range Leader!” Wagner added.

The A350-1000ULR will enable Qantas Airways to operate non-stop flights between Sydney and London, and Sydney and New York, for the first time ever, distances of almost 10,000 nautical miles with flight times of up to 22 hours. This is made possible primarily by the integration into the aircraft structure of an additional rear centre tank, which enhances aircraft performance and increases range by 1,000 nautical miles.

The A350-1000ULR is the fourth passenger variant of the A350 Family, joining the A350-900, A350-900ULR and A350-1000. The passenger line-up will soon be joined by the all-new A350F freighter, also under development at Airbus, with first flight planned later this year. At the end of October 2026, the A350 Family had won 1,628 orders from 70 customers, with more than 740 aircraft already flying with 42 operators, primarily on long-haul services across the globe.

Qantas has ordered 12 A350-1000ULRs under Project Sunrise, with the first aircraft scheduled for delivery next April and entry into service on the Sydney-London route later in the year. The carrier also has 12 standard A350-1000s on order for future operation across its long-haul network.

The crew on board comprised Airbus test pilots Xavier Pepin, Vincent Sibelle and Josef Bayoud; Qantas pilots Captain Andrew Coull and Captain David Summergreene; Airbus flight test engineers Laurent Rossignol, Nicolas Granier, Tuan Do, Alexia Plumet and Jaime Angoloti; Airbus design engineers Stefan Gumm and Carsten Obermann; and the International Aeronautical Federation’s Gilles Darriau.

Note: The record flight itself took place on 27-28 July 2026; Airbus’s announcement and the Guinness World Records ratification came more than three months later, on 9 November 2026. This gap reflects the time taken for independent data validation and formal certification rather than any discrepancy in the source material.
