A specially modified Airbus A350 touched down in Toulouse, France, on Tuesday after completing what is believed to be the longest commercial flight in history — a 24-hour, 24-minute journey from Melbourne, Australia, covering 23,075 kilometres across two oceans and three continents. The flight, conducted as part of Qantas's long-running Project Sunrise initiative, beat the previous record of 22 hours and 42 minutes set by a Boeing 777-200LR in 2005 on a flight from Hong Kong to London.

The aircraft — an Airbus A350-1000ULR, where ULR stands for "ultra long range" — is fitted with an additional 20,000-litre rear centre fuel tank, bringing its total fuel capacity to more than 188,000 litres. On board for the test were eight Airbus crew members, two Qantas pilots, and two Airbus engineers, who monitored the plane's modified fuel architecture, cabin noise levels, and air circulation systems throughout the flight. The route tracked northward over the Pacific and Atlantic oceans, passing through two sunsets and two sunrises before landing at Airbus's manufacturing facility in Toulouse, south-west France. A previous test flight in the same campaign flew the route in reverse — from Toulouse to Melbourne — in just over 19 hours.

Qantas has ordered 12 of the modified jets as part of Project Sunrise, a plan that has been in development for nine years but has faced repeated delays. The first aircraft is due for delivery in April 2027, with daily non-stop commercial services between Sydney and London planned to begin in October 2027. The airline also intends to launch non-stop Sydney–New York flights. Each aircraft can seat 238 passengers and will cut what was historically a five-day journey on the so-called "Kangaroo Route" to London down to approximately 19 to 21 hours, depending on routing and winds. Qantas already operates non-stop flights between Perth — located thousands of kilometres west of Melbourne — and London, but direct services from Australia's east coast to Europe have never existed.

The flight captured extraordinary public attention. Flight-tracking service Flightradar24 reported more than 3.6 million people followed the journey in real time, making it the second-most-tracked flight ever on the platform, behind only the 2022 flight carrying the coffin of Queen Elizabeth II. For context, the current holder of the world's longest scheduled commercial route is Singapore Airlines, whose Singapore–New York service covers 15,350 kilometres and lasts more than 18 hours using a standard variant of the same A350 family.

The record-setting test marks a significant milestone for both Airbus and Qantas, demonstrating that the technology needed to sustain ultra-long-haul passenger travel is operationally viable. If Project Sunrise proceeds on schedule, it will fundamentally reshape long-distance travel between Australia and the northern hemisphere, eliminating the stopovers in cities like Singapore or Dubai that have long defined the journey.
