By planned non-stop distance, the claim is strong
Airbus describes Sydney to London or New York missions as almost 10,000 nautical miles. Qantas plans Sydney to London as the first Project Sunrise route from October 2027.
Singapore Airlines published approximately 9,000 nautical miles for its Singapore to New York route when launching the service. On those official figures, the planned Qantas route is longer by distance.
Duration is a moving measurement
Airbus gives Project Sunrise a flight time of up to 22 hours. Singapore Airlines currently describes its non-stop Singapore to New York journey as approximately 18 hours 25 minutes.
Actual block and airborne times change with winds, routing, traffic and airport operations. A single unusually slow flight should not automatically redefine the normal scheduled comparison.
Operating and planned are different categories
Singapore to New York is an operating passenger service. Sydney to London remains planned and subject to aircraft certification, delivery and regulatory approvals.
Until Qantas begins carrying passengers, it is more precise to call it the planned longest service rather than replace the current operating record in advance.
Commercial and special flights should not be mixed
Record positioning flights, delivery flights and endurance tests can travel great distances without being scheduled passenger services. Project Sunrise is notable because Qantas intends to sell regular non-stop seats between the cities.
The comparison should therefore keep the same category on both sides: scheduled, non-stop, commercial passenger operation. Adding a stop or relying on an exceptional test changes the question.
The answer as of July 2026
Project Sunrise is designed to become the world's longest commercial passenger service by the distance and duration figures published by Airbus and Qantas. Its planned October 2027 launch would move the benchmark if service begins as described.
For now, Singapore to New York remains the established non-stop reference. The final ranking should be checked again when Qantas publishes the operating schedule and the first revenue flight is completed.
Four measurements can produce four different headlines
Great-circle distance is the shortest path between two points on the globe. An aircraft's planned track can be longer because of winds, weather, restricted airspace and air-traffic routing. Neither figure is exactly the same as distance actually flown on one day.
Time also has two common meanings. Airborne time runs from take-off to landing, while scheduled or recorded block time includes ground movement at both airports. A fair record comparison needs the same definition on both sides.
The current benchmark is still operating
Singapore Airlines currently says it operates a daily non-stop service between Singapore and New York and describes the direct journey as approximately 18 hours 25 minutes. That confirms the route remains a live benchmark, not only a historic announcement.
Its published 2018 launch material put the route at approximately 9,000 nautical miles. Airbus describes the future Sydney missions as almost 10,000 nautical miles, so the planned distance claim remains materially larger on the companies' own figures.
What would settle the record after launch
Qantas says daily Sydney to London service is planned from October 2027, with tickets due to go on sale in February 2027. A published timetable will make a scheduled-duration comparison possible before the first flight.
The operating record will be clearer after the first revenue services establish actual tracks and times. Until then, the accurate wording is simple: Sydney to London is the planned future record holder, while Singapore to New York is the current operating reference.
