Longest Flight in the World – Xiamen Airlines’ 19h 20m Record
Commercial aviation reached new endurance extremes in October 2025 when Xiamen Airlines inaugurated a nonstop service connecting New York to Fuzhou that clocks in at 19 hours and 20 minutes. This route displaced Singapore Airlines from the top position, which had previously operated the longest-duration flights between Singapore and the New York area using specialized ultra-long-range aircraft.
Ultra-long-haul travel continues to eliminate stopovers between distant continents, testing the limits of both fuel-efficient engineering and human adaptability. These marathon connections span nearly a full rotation of the Earth, offering passengers direct access to markets previously requiring multi-segment journeys.
What Is the Longest Flight in the World?
Xiamen Airlines JFK–FOC
19 hours 20 minutes
7,077 miles
Boeing 787-9 Dreamliner
Xiamen Airlines secured the duration record in October 2025, utilizing a Boeing 787-9 Dreamliner for the transpacific corridor between John F. Kennedy International Airport and Fuzhou Changle International Airport. Aviation data confirms this route averages 19 hours and 20 minutes of block time, depending on prevailing winds and routing adjustments.
- The 19-hour threshold represents the first time a regularly scheduled commercial service has exceeded this duration mark.
- Singapore Airlines retains the second and third positions with its Newark and JFK services, operating at just under 19 hours.
- Distance and duration do not always correlate; longer routes sometimes take less time due to favorable jet streams.
- All current record-holding routes utilize wide-body twin-engine aircraft optimized for extended range.
- First-class cabins have been eliminated from the longest-duration flights to reduce weight and fuel consumption.
- Crew members work in rotation shifts exceeding 18 hours, requiring specific rest protocols.
- Qantas has announced plans to surpass current records with 20-hour services entering the market by 2027.

Which Airline and Aircraft Operate the Longest Flights?
Xiamen Airlines and the Boeing 787-9 Dreamliner
Xiamen Airlines configures the Boeing 787-9 Dreamliner for the JFK–FOC corridor, covering 7,077 miles without technical stops. Operational data indicates the carrier optimized seating density and fuel capacity to achieve the 19-hour duration, though specific interior configurations remain proprietary.
Singapore Airlines and the A350-900ULR
Singapore Airlines maintains ultra-long-haul operations using the Airbus A350-900ULR (Ultra Long Range), a variant specifically engineered for extended endurance. Cabin configuration details reveal the airline limited capacity to 161 passengers across business and premium economy classes exclusively.
The A350-900ULR operates with no first-class cabin and reduced total seating to prioritize fuel efficiency over passenger density. This trade-off enables the aircraft to carry sufficient fuel for 9,500+ mile sectors while maintaining viable commercial economics.
History and Timeline of World’s Longest Flights
The A340-500 Era and Polar Routes
Singapore Airlines initially established the ultra-long-haul benchmark in June 2004, launching SQ21 from Newark to Singapore utilizing the Airbus A340-500. Historical records document this 15,344-kilometer route routing near the North Pole, requiring approximately 18 hours of flight time and establishing the first regular nonstop service exceeding 15,000 kilometers.
The Pandemic Interruption and Strategic Relaunch
Operations suspended in March 2020 as global travel restrictions eliminated demand for intercontinental business travel. Service records indicate the airline relaunched New York connections in November 2020 using the A350-900ULR, initially routing to JFK as SQ23/SQ24 before resuming Newark operations in 2022.
The October 2025 Record Transfer
Xiamen Airlines’ October 2025 inauguration of JFK–FOC services displaced Singapore Airlines from the duration record, though Singapore retained distance superiority on its Singapore–New York routes. This transition marked the first time a Chinese carrier held the longest-flight distinction.
Upcoming Longest Flights and Future Records
Qantas Project Sunrise Preparations
Qantas has announced plans to initiate Sydney–London and Sydney–New York nonstop services by 2027, marketed as Project Sunrise. Route specifications indicate these sectors will exceed 10,000 miles and approach 20 hours of flight time, utilizing the Airbus A350-1000 with enhanced fuel capacity and modified cabin pressure systems.
Enhanced Passenger Wellness Systems
The airline has indicated these aircraft will incorporate specialized wellness features designed to mitigate physiological stress during double-sunrise journeys, including adjusted humidity levels and lighting cycles synchronized to destination time zones.
Project Sunrise represents the aviation industry’s next endurance frontier, with projected durations potentially exceeding 20 hours. Success depends on regulatory certification of the A350-1000 modifications and crew fatigue management protocols currently under evaluation.
Longest Flight by Distance vs Duration and Other Records
Distance Leaders vs Time Leaders
Singapore Airlines’ Singapore–JFK route covers 9,537 miles, exceeding Xiamen Airlines’ 7,077-mile JFK–FOC distance, yet takes less time due to favorable eastbound jet streams. This discrepancy illustrates that distance and duration records represent distinct metrics; routing variations over the Pacific versus polar corridors create significant time differentials.
Non-Commercial and Military Comparisons
Commercial ultra-long-haul operations exceed typical private aircraft capabilities; the Gulfstream G650ER maintains approximately 7,500 nautical miles range, while the A350-900ULR achieves 9,700 nautical miles. Historical military records include the 1949 Voyager circumnavigation, though such operations lack the scheduled passenger service characteristics defining commercial aviation records.
Aviation records distinguish between scheduled commercial services and special military or experimental flights. The current commercial duration and distance records apply exclusively to regular passenger operations available for public booking, excluding private or government-operated missions.

The Engineering Behind Ultra-Long-Haul Routes
Ultra-long-haul connectivity responds to premium market demand for direct city-pair links avoiding hub transfers. Advanced aerospace developments demonstrate how modern twin-engine platforms achieve ETOPS certification allowing extended over-water operations previously requiring quad-jet aircraft.
Fuel efficiency improvements through carbon-fiber composites and aerodynamic optimization enable viable economics for 19-hour sectors. Airlines sacrifice passenger density—eliminating first-class cabins and limiting total seats—to accommodate the additional fuel weight required for transpolar and transpacific wind patterns.
The premium travel sector continues driving demand for these connections, accepting premium cabin configurations in exchange for time savings exceeding traditional one-stop routings through intermediate hubs.
Expert and Official Sources
Crew members on 18-hour sectors manage significant physical and emotional strain, requiring specific rotation protocols and rest facilities aboard the A350-900ULR to maintain safety standards throughout the marathon duty periods.
