In an increasingly interconnected world, air travel has become an integral part of our lives, connecting distant cities and bridging continents. As technology advances and aviation capabilities expand, airlines are continuously pushing the boundaries of non-stop flight routes, allowing passengers to traverse vast distances without layovers or interruptions. In this article, we explore the ten longest non-stop airline routes.

 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.

Top 10 Longest Flight Routes in 2023

1. New York (JFK) to Singapore Changi (SIN): Singapore Airlines.

Currently, the longest commercial flight that can be scheduled is from New York John F. Kennedy Airport to Singapore Changi. With a length of 15,332 km, this route has topped the list since 2021 and takes an average of 18 hours, 40 min.

2. Newark Liberty International (EWR) to Singapore Changi (SIN): Singapore Airlines.

Singapore Changi is the second-longest flight route in 2023 and provides direct connections to other Asian nations and Australia. In fact, the Newark–Changi route is only 3 km less than the longest route, and during 2004–2013 and again from 2018–2020, this was the world’s longest route prior to Singapore Airlines’ introduction of flights from JFK to Singapore.

3. Perth (PER) – London Heathrow (LHR): Qantas Airways.

This is the only route in our top 10 that features a European airport, with a scheduled flight time of 17 hours and 45 minutes, as Qantas’s Darwin to Heathrow route, which took eighth place in last year’s rankings, is no longer in service.

4. Dallas Fort Worth (DFW) – Melbourne (MEL): Qantas Airways.

This year, Dallas Fort Worth has consistently appeared on our monthly list of busiest airports because of its availability of connecting flights for Australian tourists to 193 US locations. The 17 hours 35-minute trip from Dallas to Melbourne is planned.

5. Auckland International (AKL) – New York (JFK): Air New Zealand, Qantas.

This will be the first nonstop Air New Zealand route to New York, beginning in 2022. The flight is expected to last 16 hours and 15 minutes. When Qantas entered the AKL-JFK market in 2023, Air New Zealand faced some competition.

6. Auckland International (AKL) – Dubai International (DXB): Emirates.

This flight was the longest in the world in 2016 at 14,193 kilometers, and it only took seven years for it to drop to sixth place on the list, showing how quickly things can change in the aviation industry! The journey is expected to take 17 hours and 5 minutes to complete, and it will land at one of the busiest international airports.

7. Los Angeles (LAX) – Singapore Changi (SIN): Singapore Airlines.

On the list of longest non-stop commercial flights, Singapore Changi Airport makes its third and final appearance at position number 7, on a route that was first taken by United Airlines in 2016 and was at the time the longest scheduled non-stop flight from the US.

8. Bengaluru (BLR) – San Francisco (SFO): Air India.

The  Air India travel to make it into the top 10 is the 13,982 km route from Bengaluru in Southern India to San Francisco Airport on the US west coast. Recently, they confirmed orders for 470 new aircraft to add to their fleet, including 70 wide-bodied aircraft, so keep an eye on this sector.

9. Dallas Fort Worth (DFW) – Sydney Kingsford Smith (SYD): Qantas.

With a total distance of 13,802 kilometers, this route is the fourth on the list for Qantas Airways and will rank ninth in July 2023. In 2014 and 2015, it was the longest regularly scheduled commercial flight in the world. Due to the fact that this flight crosses the International Date Line, it arrives in Sydney two days after leaving. It takes off in the evening and lasts 16 hours and 45 minutes.

10. New York (JFK) – Manila Ninoy Aquino (MNL): Philippine Airlines.

This is one of two routes that appear in July 2023 that did not appear in the top ten in July 2022, the other being DFW-SYD. It will take the position of United’s Houston-Sydney route, which has been converted to a seasonal route and will resume service in October.
