Qantas to Launch World’s Longest Non-Stop Flight From Sydney to London

Qantas will launch the world’s longest non-stop commercial flight between Sydney and London Heathrow in October 2027. According to the airline, passengers will spend 22 consecutive hours in the air using a specialized Airbus A350-1000 ULR. The aircraft features an additional 20,000-liter fuel tank to cover nearly 10,000 nautical miles.

How does Qantas achieve a 22-hour non-stop flight?

The airline is utilizing a modified Airbus A350-1000 ULR, a variant that completed its first flight recently. To make the Sydney-to-London route viable, Airbus integrated an extra fuel tank holding 20,000 liters. This modification increases the aircraft’s range by 1,000 nautical miles, according to Airbus technical specifications reported by flysmart24.

This operation is the result of a multi-year development effort titled “Project Sunrise.” The project focuses on removing the need for stopovers on ultra-long-haul journeys, which traditionally required technical stops for refueling or crew changes.

What will the passenger experience be like on Project Sunrise?

Qantas is redesigning the cabin to mitigate the physical toll of a 22-hour journey. The aircraft offers four distinct classes: First Class, Business Class, Premium Economy, and Economy. Qantas confirmed that every class will feature extra legroom to assist with circulation and comfort.

Beyond seating, the airline has added dedicated relaxation areas. A promotional video released by Qantas on Wednesday showcases these zones, which are intended to provide maximum comfort for passengers trapped in the cabin for nearly a full day.

Which routes are part of the ultra-long-haul expansion?

London is the primary destination for the initial launch. However, Qantas intends to expand this capability to other global hubs. The airline has stated it plans to introduce a similar non-stop service to John F. Kennedy International Airport (JFK) in New York.

This shift represents a significant change in aviation logistics. By eliminating the stopover, Qantas reduces total travel time and removes the operational complexity of landing in intermediate cities. Ticket sales for these routes are scheduled to begin in February 2027.

How does this compare to standard long-haul flights?

Most current long-haul flights cap at 17 to 19 hours. The jump to 22 hours introduces new challenges for crew fatigue and passenger health. While a standard A350 is designed for efficiency, the ULR (Ultra Long Range) variant prioritizes fuel volume over passenger density to achieve these distances.
