**Updated April 2025**
The world’s first commercial flight took off from St Petersburg, Florida on January 1st 1914, and landed about 30 minutes later in Tampa, Florida, covering a distance of 17km. Since then, advances in aviation technology have made it possible to fly thousands of kilometers non-stop, and as of April 2025, the list of the world’s top 10 longest flights includes destinations in Europe, Asia, North America, and the Middle East.
Using OAG’s airline schedules data, our table of the longest routes ranks commercial flights by Great Circle Distance (GCD) in kilometers. GCD is a way of measuring a flight’s length, taking into account the fact that the Earth is spherical, and therefore the shortest route for a flight to take is not a straight line drawn from point to point on a 2D map. Let's take a look at the current longest flights in the world.
The top 20 Longest Commercial Flights Leaderboard
Exploring the top 10 longest flights
1. The World’s Longest Flight: New York (JFK) to Singapore Changi (SIN)
Distance (GCD): 15,332km
Airline: Singapore Airlines
Aircraft: Airbus A350-900
New York John F Kennedy Airport – Singapore Changi is currently the longest commercial flight it is possible to book. At 15,332km, this route has been at the top of the table since 2021, and takes an average of 18 hours and 40 minutes to complete.
2. Newark Liberty International (EWR) to Singapore Changi (SIN)
Distance (GCD): 15,329km
Airline: Singapore Airlines
Aircraft: Airbus A350-900
Offering direct links to other Asian countries and Australia, Singapore Changi also features in the second longest flight route of Summer 2025. In fact, the Newark – Changi route is just 3km shorter than the longest route, and until Singapore Airlines introduced flights from JFK to Singapore this was the world’s longest route from 2004-2013 and again from 2018-2020.
3. Auckland (AKL) - Doha (DOH)
Distance (GCD): 14,526km
Airline: Qatar Airways
Aircraft: Airbus A350-900
Having been dropped a couple of years after its 2017 launch during the Covid-19 pandemic, this route came back in 2024. Auckland-Doha was once the world's longest non-stop commercial flight but now sits in a respectable third place on our top ten list.
4. Perth (PER) – London Heathrow (LHR)
Distance (GCD): 14,499km
Airline: Qantas Airways
Aircraft: Boeing 787-9
With a scheduled flight time of 17 hours and 45 minutes, this is one of just two routes in our top 10 that features a European airport, both of which depart from Perth. This route was briefly paused in 2024 due to tensions in the Middle East, taking an alternative route with a fuelling stop in Singapore.
5. Dallas Fort Worth (DFW) – Melbourne (MEL)
Distance (GCD): 14,468km
Airline: Qantas Airways
Aircraft: Boeing 787-9
Dallas Fort Worth has been a permanent fixture on our monthly list of busiest airports this year, offering Australian visitors onward flights to around 200US destinations. The flight from Dallas to Melbourne is scheduled for 17 hours 35 minutes.
6. Paris Charles De Gaulle (CDG) - Perth (PER)
Distance (GCD): 14,265km
Airline: Qantas Airways
Aircraft: Boeing 787-9
This is one of two routes in the top 10 longest commercial flight routes that includes a European airport, both of which depart from Perth, Australia.
7. Auckland International (AKL) – New York (JFK)
Distance (GCD): 14,209km
Airline: Air New Zealand, Qantas
Aircraft: Boeing 787-9
Launched in 2022, this is the first Air New Zealand route flying non-stop to New York. The scheduled flight time is 16 hours 15 minutes. In 2023, Qantas entered the AKL-JFK market, introducing some competition for Air New Zealand.
8. Auckland International (AKL) – Dubai International (DXB)
Distance (GCD): 14,193km
Airline: Emirates
Aircraft: Airbus A350
In 2016, this was the world’s longest flight at 14,193km, and the fact that it took just a few years to move down to 8th place on the list demonstrates how quickly things can change in the world of aviation! The flight is scheduled to last 17 hours and 5 minutes, landing in one of the world’s busiest global airports.
9. Shenzhen (SZX) - Mexico City Juarez Intl (MEX)
Distance (GCD): 14,124km
Airline: China Southern
Aircraft: Airbus A350
This is the only flight on this list to feature either a Chinese or Latin American airport, and the only one operated by a Chinese carrier. Interesting fact: This route operates direct from Shenzhen to Mexico City but returns with a layover in Tijuana because of the high altitude at Mexico City.
10. Los Angeles (LAX) – Singapore Changi (SIN)
Distance (GCD): 14,096km
Airline: Singapore Airlines
Aircraft: Airbus A350-900
Singapore Changi Airport makes its third and final appearance at number 10 on the list of longest non-stop commercial flights, on a route that was first flown by United Airlines in 2016 and was, at the time, the longest scheduled non-stop flight from the US.

Aircraft On The Longest Routes
Airbus A350-900
Range: Up to 18,000km
Engine: Rolls-Royce Trent XWB
Capacity: 300-500 passengers
Up until as recently as 2016, the world’s longest flights were flown by four-engine aircraft, but one third of the longest routes now operate on the wide-bodied, twin-engine Airbus 350-90: JFK-SIN, EWR-SIN, LAX-SIN. Since its entry into service in 2015, the global A350 fleet has completed more than 1,025,000 flights on more than 1000 routes.
Airbus A350-1000
Range: Up to 16,100km
Engine: Rolls-Royce Trent XWB-97 turbofans
Capacity: 350-410 passengers
The Airbus A350-1000 has the longest fuselage of the A350 family, seven-metres-longer than Airbus’ A350-900 version. This aircraft also boasts the quietest twin-aisle cabin in the skies and ambient lighting that claims to minimize the effects of jet-lag.
Boeing 787-9
Range: Up to 15,400km
Engine: General Electric GEnx or Rolls-Royce Trent 1000
Capacity: 296 passengers
Another twin-engine aircraft, the Boeing 787-9, otherwise known as the Dreamliner, flies four out of ten of the longest nonstop flights: LHR-PER, DFW-MEL, AKL-JFK and CDG-PER. In addition to Qantas and Air New Zealand, more than 70 other airlines count the B787-9 in their fleets, including All Nippon Airways, which has 40, the most of any airline.
Airbus A380-800 Passenger
Range: Up to 15,700km
Engine: Rolls-Royce Trent 900, Engine Alliance GP7000
Capacity: 500 + passengers
Unlike the other aircraft on this list, the Airbus A380-800 has four engines. It’s currently the world’s largest passenger airliner with its double-deck design. Production of the A380 ended in 2021, but it is still a favored aircraft and as long-haul travel returns post-pandemic, more A380s are taking to the skies again.
Upcoming Record-Breaking Flights
The next flight set to break the record for the longest nonstop air journey will likely happen in 2027, when Qantas plans to operate flights from New York to Sydney using a specially designed Airbus A350. The airline has included a ‘wellness’ space on board and has been researching ways to help travelers tackle jet lag, which will be important because the 16,020km flight will last more than 20 hours. The launch of this route was planned for 2025 but has been put back due to a delay in the delivery of the aircraft.
