National Airlines, a Florida-based cargo and charter carrier, has just completed what is widely reported as the longest commercial cargo flight ever flown by a Boeing 777 Freighter. On August 4, the airline flew a 777F nonstop from Scotland to Australia, covering a distance of 9,850 nautical miles (11,315 miles or 18,240 km) over the course of the flight. In total, the aircraft and crew remained airborne for nearly 20 hours on their marathon journey.

The record-setting flight, operated on behalf of UK-based aviation services firm Golden Aviation, quickly captured the attention of aviation enthusiasts worldwide, with nearly 40,000 people tracking the flight’s journey across the world. The flight also became the second record-breaking flight to involve Melbourne Airport in the past two weeks, with Qantas Project Sunrise recently operating the world’s longest flight ever from Melbourne to Toulouse, France.

The flight, operating as NCR820, departed Prestwick in Scotland shortly after midnight local time on August 4th, touching down in Melbourne at 4:52am the next day on August 5th. In total, the aircraft remained airborne for nearly an entire day, with the exact flight time coming out to 19 hours and 24 minutes. Reported figures for the flight put the distance at roughly 9,850 nautical miles, about 11,315 statute miles or 18,240 kilometers when converted.

The mission was reportedly to transport a replacement engine component for a Boeing 787-8 Dreamliner that had been grounded in Australia since July 25, according to Analytic Flying on X. The grounded aircraft, believed to be registered as VH-VKF and operated by Australia low-cost carrier Jetstar, was rumored to be in need of new thrust reversers for its GEnx engines, with Prestwick being home to a GE maintenance and overhaul facility.

While the flight was not the longest ever to be operated by a Boeing 777-200 family aircraft (that title is held by a 2005 flight from Hong Kong to London on a Boeing 777-200LR, flying for 22 hours and 42 minutes), Tuesday’s flight is believed to be the longest commercial B777F flight ever operated for another airline, with Golden Aviation contracting National to operate the one-off service

Commenting on the milestone flight, National Airlines said:

“We are proud to have achieved what is believed to be the world’s longest commercial B777F flight for another airline. Thank you to our customer Golden Aviation for their support!”

N792CA was the aircraft used for the flight and was a relatively new addition to National Airlines’ fleet of now three Boeing 777F aircraft, according to planespotters.net. N792CA was delivered to National in May 2026, the second of three deliveries since April. All three aircraft are part of a four aircraft order placed with Boeing back in 2024, with the final 777F expected to be delivered before the end of the year.

While the 777F’s performance is strong for a large cargo aircraft, the Prestwick to Melbourne route pushed the 777F to nearly double its published maximum range of 5,000 nautical miles (9,260 km) with a 107-tonne load. The capability to operate the nearly 10,000 nautical mile (18,520 km) journey without any fuel stops likely came from a substantially reduced payload while still fueled to maximum capacity.

In terms of routing, the flight’s journey across Europe and Asia followed a relatively standard flight plan. After departing the United Kingdom, the 777F flew east across Germany and Eastern Europe before passing north over Turkey and Iran. The crew then turned south over Tajikistan, crossing over Pakistan, India, Singapore and Indonesia before finishing the final stretch across Australia to Melbourne.

Not The Only Recent Long-Haul Milestone To Melbourne

National Airlines’ 777F flight comes at a usually active moment for ultra-long-haul aviation record. Just eleven days earlier, on July 24, 2026, an Airbus A350-1000ULR completed the world’s longest commercial aviation flight ever, flying for over 24 hours and 12,000 nautical miles (22,220 km) from Melbourne to Toulouse. The flight officially became the longest flight ever somewhere over the United Kingdom, surpassing the 2005 Hong Kong to London flight previously mentioned.

Seen against that backdrop, National Airlines’ achievement is even more impressive, as the 777F was never intended for ultra-long-haul missions of this scale. Pulling off a nearly 10,000 nautical mile flight on an aircraft type built primarily for shorter, heavier cargo routes rather than the specifically designed nature of the A350-1000ULR for ultra-long-haul flying speaks to the careful planning and weight management required for this flight.
