For most of the past two decades, the outer limit of how far a passenger jet could fly without landing was set by a single aircraft, and nobody seriously challenged it. That changed last month, when an Airbus test aircraft stayed airborne for over a full day and quietly redrew the map of what long haul travel can look like.
The aircraft in question was an Airbus (EPA: AIR) A350-1000ULR, a variant built specifically for Qantas as part of its Project Sunrise initiative. On July 23rd, the jet flew from Toulouse, France to Melbourne, Australia, then a few days later made the return trip the long way, crossing the Pacific, the United States and Canada before landing back in France. The return leg alone took 24 hours and 24 minutes and covered roughly 23,076 kilometers, making it the longest flight ever completed by a commercial aircraft type during testing.
What makes this possible is not a dramatically different airframe but a set of targeted modifications. The ULR (Ultra Long Range) variant adds an extra fuel tank in the rear of the aircraft, boosting capacity by around 20,000 liters and extending range from the standard A350 1000’s roughly 9,000 nautical miles to closer to 10,000. That extra fuel comes at a cost, though. Where a standard A350 1000 can seat more than 350 passengers, the ULR version tops out at 238, a trade off airlines accept when the goal is opening routes that were previously impossible to fly nonstop.
The record this flight broke had stood since 2005, when Boeing (NYSE: BA) delivered a 777 200LR from Hong Kong to London, covering about 11,664 nautical miles in 22 hours and 42 minutes. That aircraft remains Boeing’s longest-range model in service today, capable of roughly 9,400 nautical miles nonstop, but it has effectively had no real competition at the extreme end of the range spectrum until now.
Beyond those two aircraft, the field narrows quickly, but it does not disappear. The Airbus A350-900ULR, a highly customized variant built exclusively for Singapore Airlines, holds a maximum range of about 9,700 nautical miles and currently operates the longest scheduled commercial route in the world, connecting New York and Singapore in close to 19 hours. The standard Airbus A350-900 follows at just over 8,100 nautical miles, already enough to outperform most of Boeing’s long-haul lineup on paper. Rounding out the group is Boeing’s own 787 9 Dreamliner, which reaches about 7,635 nautical miles and remains the backbone of ultra long haul flying for airlines that have not yet moved to the A350 family. Together, these five aircraft mark the outer edge of what commercial long-haul flying can do today.
The commercial logic behind all this testing belongs to Qantas Airways (ASX: QAN). Project Sunrise has been in development for years with one goal in mind, connecting eastern Australia directly to London and New York without a stopover. Those routes have never existed because no aircraft could carry passengers and enough fuel to make the distance work economically. Qantas expects to take delivery of its first A350 1000ULR in April 2027, with the inaugural Sydney to London flight targeted for October 2027.
It is worth being clear about what this flight actually represents. It was a development test, not a passenger service, and formal certification of the distance record by the Fédération Aéronautique Internationale is still pending. But the underlying trend is bigger than one aircraft or one airline. Airbus’s order book for the A350 family had reached 1,579 orders from 68 customers by the end of April 2026, and Boeing’s 787 program has accumulated more than 2,600 orders of its own, evidence that airlines around the world are increasingly willing to pay for range as a feature rather than treating it as an afterthought.
For twenty years, the industry treated the 777 200LR’s record as a ceiling, a number nobody had a reason to chase. Airbus just proved it was a floor. The next fight will not be over who can build a longer runway of test flights, it will be over who can turn that extra range into a route network passengers actually want to fly, and that contest has already begun.
