Airbus A350-1000ULR flew for more than 24 hours, but fell well short of aviation’s absolute record

The Airbus A350-1000ULR covered 23,076 km from Melbourne to Toulouse in 24 hours and 24 minutes. That is farther than the benchmark Guinness World Records currently lists for the longest flight by an unmodified commercial aircraft, but nowhere near aviation’s absolute distance record. Nor was this a passenger service: the aircraft carried a test crew, flight-test instrumentation and enough fuel to remain aloft for almost a full day.
