Longest Non-Stop Flights in the World, these five words have taken up permanent residence in my head ever since I sat in seat 34K for eighteen straight hours between New York and Singapore, watching the little airplane icon on the seatback screen inch across an ocean, then a continent, then another ocean.
I am Khushi Vaid, and as a travel author here on TravellerScoop, I have made it my mission to actually experience the routes I write about instead of just recycling numbers from a press release.
So when people ask me about the longest non-stop flights in the world, I do not just give them a list, I give them the real distances, the real flight times, and the real feeling of what it is like to be strapped into a metal tube for almost a full day.
In this guide, I am breaking down the five longest nonstop flights in the world flying right now in 2026, backed by verified airline schedules and great-circle distance data.
If you are the kind of traveller who gets a little thrill from knowing you are about to spend more hours airborne than most people spend at work in two days, this one is for you.
I am also going to tell you what is coming next, because the title of “longest non-stop flight in the world” is about to change hands in a very big way.
What Actually Counts as an Ultra-Long-Haul Flight?
Before I get into the ranking, let’s get one thing clear, because a lot of “longest flight” articles online mix this up. The longest non-stop flights in the world are measured by great-circle distance, the shortest possible path between two airports along the curve of the Earth, not by how long the flight actually feels in your cramped economy seat.
Anything over roughly 13,500 km or 14+ scheduled hours falls into the “ultra-long-haul” category, and only a handful of aircraft in the world are actually built to fly that far without refueling.
Two aircraft dominate every single ranking of the longest non-stop flights in the world today: the Airbus A350-900ULR (Ultra Long Range), which is flown exclusively by Singapore Airlines, and the Boeing 787-9 Dreamliner, used by Qantas, Air New Zealand, and United on routes between 13,000 and 14,500 km.
The 787’s lower cabin altitude pressurization (about 1,800 meters instead of the usual 2,400) is honestly the reason I can still walk in a straight line after landing.
5 Longest Non-Stop Flights in the World Right Now
Here is the ranking of the longest non-stop flights in the world currently bookable by any traveler, based on great-circle distance and airline-published block times as of mid-2026.
1. New York (JFK) to Singapore (SIN): Singapore Airlines, 15,349 km
This is it, the current titleholder for the longest non-stop flight in the world that 2026 has to offer. Singapore Airlines flight SQ23 covers 15,349 km (9,537 miles) and takes roughly 18 hours and 50 minutes westbound.
I flew this exact route last year, and I can tell you the cabin, a two-class layout of just 161 seats in business and premium economy only, no economy at all, is built entirely around one goal: getting you through nearly 19 hours in one piece.
Singapore Airlines has operated some version of this route since 2004, making it the pioneer of the world’s longest commercial flight route for two decades.
2. Newark (EWR) to Singapore (SIN): Singapore Airlines, 15,344 km
Only five kilometers shorter than its JFK sibling, the Newark to Singapore route takes about 18 hours 45 minutes and is flown by the same Airbus A350-900ULR.
What I find fascinating is that this was actually the original ultra-long-haul route Singapore Airlines launched back in 2004 before it was briefly discontinued and then relaunched in 2018, proof that demand for the longest non-stop flights in the world never really went away; it just needed better aircraft to make it profitable again.
3. Auckland (AKL) to Doha (DOH): Qatar Airways, 14,535 km
Qatar Airways’ Auckland-Doha route is one of the most underrated entries on any list of the longest non-stop flights in the world.
Flown on an Airbus A350-1000, this 14,535 km journey takes about 16 hours 34 minutes and quietly connects New Zealand to the Middle East and, from there, to dozens of onward destinations in Europe and Africa without ever touching Australia or Southeast Asia.
It is a genuinely clever piece of route planning, and Qatar Airways rarely gets the credit it deserves for pulling it off.
4. Perth (PER) to London (LHR): Qantas, 14,499 km
This is the flight that first proved ultra-long-haul travel could work on a twin-engine Boeing 787-9 rather than a giant four-engine jet. At 14,499 km and roughly 17 hours 25 minutes, Perth to London was Qantas’s opening move in what later became “Project Sunrise.”
Every time someone tells me the longest non-stop flights in the world are only getting longer because of bigger planes, I point them to this route, it happened because of a smarter, lighter one instead.
5. Dallas (DFW) to Melbourne (MEL): Qantas, 14,472 km
Rounding out the top five, Qantas’s Dallas to Melbourne service covers 14,472 km in about 17 hours 13 minutes on a Boeing 787-9. It is the longest scheduled flight between the Americas and Australia, and honestly, it exists because Dallas Fort Worth is one of the few U.S. hubs with the connecting network to make a 17-hour flight commercially viable on both ends.
This route quietly closed a huge gap in direct US-Australia connectivity when it launched.

What's Coming: A New World's Longest Commercial Flight Route in 2027
Here is the part that genuinely excites me as an aviation nerd. Every ranking of the longest non-stop flights in the world is about to get reshuffled. Qantas is preparing “Project Sunrise”, a non-stop Sydney to London Heathrow service using a specially modified Airbus A350-1000ULR, cabin-configured for around 238 passengers with dedicated crew rest bunks and even a passenger stretching zone.
Covering approximately 17,000 km in around 20 hours, it is scheduled to enter service in October 2027 and will instantly become the new longest non-stop flight in the world 2026-and-beyond title holder, pushing every single route on this list down a rank. If ultra-long-haul flying interests you, this is the one to watch.
My Honest Tips for Surviving an Ultra-Long-Haul Flight
I have now done four of these five routes personally, and here is what actually helps when you are staring down one of the longest non-stop flights in the world from your own economy or premium economy seat:
- Hydrate obsessively. Cabin air on an 18-hour flight is brutally dry. I drink water every single time the cart passes, no exceptions.
- Walk every 90 minutes to 2 hours. Even a slow lap to the galley and back keeps circulation moving and genuinely reduces how wrecked you feel on landing.
- Sleep on airport time, not home time. I start adjusting my sleep schedule two nights before flying, and it cuts my jet lag recovery almost in half.
- Pack for the second half of the flight, not the first. Dinner service happens early; the last few hours are when you actually need snacks, lip balm, and a fresh pair of socks.
- Choose your airport wisely on both ends. A good layover or connecting airport genuinely changes how the whole journey feels, have written a full breakdown of the world’s best family-friendly airports if you are travelling with kids on one of these long routes, and a separate guide on America’s most relaxing airports if your journey starts or ends in the US.
If you are connecting through a hub in India or the Middle East on your way to catch one of these ultra-long-haul flights, I have also put together a detailed guide to the best airports in India and the Middle East worth knowing about.
And if you are still deciding whether a long non-stop or a broken-up multi-stop itinerary makes more sense for your trip, my comparison of domestic vs international travel planning walks through exactly how I make that call.
Before you book anything, it’s also worth running your route through our own Travel Budget Calculator, ultra-long-haul fares swing a lot depending on season, and it helps to know what you are actually signing up for.
Conclusion
Chasing the longest non-stop flights in the world has genuinely changed how I plan my trips. I now actively look for these routes instead of avoiding them, because skipping a layover often saves an entire day of travel, even if the single flight itself feels endless.
Whether it is Singapore Airlines’ record-breaking JFK route, Qatar Airways quietly connecting Auckland to Doha, or Qantas getting ready to make Sydney-London history in 2027, one thing is clear: the era of the ultra-long-haul non-stop flight is only getting bigger.

FAQs
How do airlines make an 18-hour flight bearable for passengers?
Airlines running the longest non-stop flights in the world typically limit cabin altitude pressurisation, serve dinner shortly after takeoff, dim cabin lights for an extended sleep window, and run a light second meal before landing, I have experienced this exact rhythm firsthand on Singapore Airlines and Qantas.
What is the longest non-stop flight in the world right now?
As of 2026, the longest non-stop flight in the world is Singapore Airlines' New York (JFK) to Singapore (SIN) route, covering 15,349 km in around 18 hours 50 minutes on an Airbus A350-900ULR.
Which airline operates the most longest non-stop flights in the world?
Singapore Airlines currently holds the top two spots for the longest non-stop flights in the world, both flown on the ultra-long-range Airbus A350-900ULR.
Will there be a longer flight than JFK to Singapore soon?
Yes. Qantas's Project Sunrise, a non-stop Sydney to London Heathrow route of roughly 17,000 km and 20 hours, is scheduled to launch in October 2027 and will become the new world's longest commercial flight route the day it enters service.
Are ultra-long-haul flights less safe than shorter ones?
No. Every one of these longest non-stop flights in the world operates under the same ETOPS (Extended-range Twin-engine Operations) certification as any short-haul flight, and modern twin-engine aircraft are certified to fly up to 370 minutes from the nearest diversion airport.
