According to the latest schedules data from OAG, the world’s top 10 longest flights as of April 2025 span Europe, Asia, North America, and the Middle East. Routes are ranked by Great Circle Distance (GCD)—the shortest path between two points on the Earth’s spherical surface. Leading the way in ultra-long-haul travel are Singapore Airlines, Qantas, and Qatar Airways, all of which offer inflight products across economy, premium economy, and business class designed to keep passengers comfortable on journeys lasting up to 19 hours.

The infographic from OAG highlights the current longest nonstop flights in the world and the airlines operating them.

Nothing illustrates the advances in aviation technology and fuel efficiency better than the fact that nine of the world’s ten longest flights are now operated by twin-engine aircraft. As recently as a decade ago, many of these routes would have been either impossible or reliant on four-engine jets like the Airbus A380. While the A380 still features on long-haul networks, today’s ultra-long-haul routes exist largely thanks to new-generation aircraft such as the Airbus A350-900 and Boeing 787-9 Dreamliner, which combine extended range with improved fuel efficiency and passenger comfort.

Here’s the 10 longest flights in more detail according to OAG

1. New York (JFK) – Singapore Changi (SIN)

• Distance: 15,332km

• Airline: Singapore Airlines

• Aircraft: Airbus A350-900
  Currently the world’s longest commercial flight, this ultra-long-haul service takes around 18 hours and 40 minutes.

2. Newark (EWR) – Singapore Changi (SIN)

• Distance: 15,329km

• Airline: Singapore Airlines

• Aircraft: Airbus A350-900
  Just three kilometers shorter than JFK–Singapore, this route previously held the world record before JFK–SIN was introduced.

3. Auckland (AKL) – Doha (DOH)

• Distance: 14,526km

• Airline: Qatar Airways

• Aircraft: Airbus A350-900
  Reintroduced in 2024 after a pandemic pause, this route was once the world’s longest when launched in 2017.

4. Perth (PER) – London Heathrow (LHR)

• Distance: 14,499km

• Airline: Qantas

• Aircraft: Boeing 787-9
  The first direct connection between Australia and Europe, this 17-hour 45-minute flight.

5. Dallas Fort Worth (DFW) – Melbourne (MEL)

• Distance: 14,468km

• Airline: Qantas

• Aircraft: Boeing 787-9
  Linking Australia to Qantas’ U.S. partner American Airlines’ hub, this route connects Melbourne travelers to more than 200 U.S. destinations.

6. Paris Charles de Gaulle (CDG) – Perth (PER)

• Distance: 14,265km

• Airline: Qantas

• Aircraft: Boeing 787-9
  Another long-haul connection from Perth, providing France with direct links to Western Australia.

7. Auckland (AKL) – New York (JFK)

• Distance: 14,209km

• Aircraft: Boeing 787-9
  Air New Zealand launched the first nonstop flight to New York in 2022, later joined by Qantas in 2023.

8. Auckland (AKL) – Dubai (DXB)

• Distance: 14,193km

• Airline: Emirates

• Aircraft: Airbus A350
  Once the longest route in 2016, it now ranks eighth, showing how quickly ultra-long-haul networks evolve.

9. Shenzhen (SZX) – Mexico City (MEX)

• Distance: 14,124km

• Airline: China Southern

• Aircraft: Airbus A350
  The only China–Latin America nonstop on the list. While westbound flights operate direct, the return requires a fuel stop in Tijuana due to Mexico City’s high altitude.

10. Los Angeles (LAX) – Singapore Changi (SIN)

• Distance: 14,096km

• Airline: Singapore Airlines

• Aircraft: Airbus A350-900
  First operated by United in 2016, this route marks Singapore Changi’s third entry in the top 10.

What’s Next?

Qantas remains on track to launch Project Sunrise in the Northern Hemisphere summer of 2027 (Australia’s winter), connecting Sydney and Melbourne non-stop to both New York City and London—an aviation milestone that will redefine long-haul travel. Once operational, these flights will become the world’s longest non-stop routes.

To make the journey more comfortable, Qantas has designed its Airbus A350-1000s with just 238 seats, making it the lowest-density version of the aircraft anywhere in the world. Around 40% of seats will be premium cabins, reflecting the demand for greater space and comfort on flights lasting more than 20 hours.
