Over the past decade, we’ve seen a trend whereby airlines have added an incredible number of new ultra long haul flights. In this post, I want to summarize the world’s longest flights, what other ultra long haul flights might be on the horizon, and share why these are more practical than in the past.
In this post:
Why ultra long haul flights are more practical than ever
Why have we seen airlines launch so many ultra long haul flights in the past several years? It primarily comes down to new aircraft technology. In the past decade, the Airbus A350 and Boeing 787 have become the backbone of many carriers’ long haul fleets, and these planes are great for airlines and passengers:
- The planes are ultra long range, and can operate some nonstop flights that previous generation aircraft couldn’t
- The planes have lower capacity than previous generation aircraft (like the Boeing 747), which opens up more viable markets; it’s much easier to profitably fill 250 seats than it is to profitably fill 400 seats
- The planes have great economics, and per-passenger fuel burn is significantly lower than previous generation aircraft
- The viability of ultra long haul flights is largely dependent on there being significant premium demand, and we’ve seen very strong global demand in recent years for premium seats
So yeah, long range, fuel efficient, low capacity aircraft have done wonders for airlines when it comes to the viability of ultra long haul city pairs. Many routes that could have previously never been profitable now make sense.

The world’s 20 longest nonstop flights as of March 2025
I’d like to take an updated look at the world’s longest flights, given how much the list has changed over the years. Let’s take a look at the 20 longest flights.
I’m basing this list on direct air distance between city pairs, since obviously Russian airspace issues are causing airlines to largely operate circuitous routings. Furthermore, I think distance is a better metric than length of flight, since winds can also have an impact on the duration of flights, and on top of that, some airlines do a lot of schedule padding.
Note that I’ll only be counting flights that are currently operating, or are expected to operate in the coming months. What’s pretty amazing to me is that all of these flights are well over 8,000 miles, which is a long way to go nonstop.
What are the world’s longest flights? Here they are, starting with the longest (I’m including the airline that operates the route, the distance, and the aircraft type used):
- Singapore (SIN) to New York (JFK) / Singapore Airlines / 9,537 miles / Airbus A350-900ULR
- Singapore (SIN) to Newark (EWR) / Singapore Airlines / 9,523 miles / Airbus A350-900ULR
- Doha (DOH) to Auckland (AKL) / Qatar Airways / 9,032 miles / Airbus A350-1000
- Perth (PER) to London (LHR) / Qantas / 9,010 miles / Boeing 787-9
- Melbourne (MEL) to Dallas (DFW) / Qantas / 8,992 miles / Boeing 787-9
- Perth (PER) to Paris (CDG) / Qantas / 8,863 miles / Boeing 787-9
- Auckland (AKL) to New York (JFK) / Air New Zealand & Qantas / 8,828 miles / Boeing 787-9
- Dubai (DXB) to Auckland (AKL) / Emirates / 8,824 miles / Airbus A380
- Shenzhen (SZX) to Mexico City (MEX) / China Southern / Airbus A350-900 / 8,791 miles
- Singapore (SIN) to Los Angeles (LAX) / Singapore Airlines / 8,770 miles / Airbus A350-900
- Bangalore (BLR) to San Francisco (SFO) / Air India / 8,701 miles / Boeing 777-200LR
- Houston (IAH) to Sydney (SYD) / United Airlines / 8,596 miles / Boeing 787-9
- Sydney (SYD) to Dallas (DFW) / Qantas / 8,578 miles / Boeing 787-9
- Manila (MNL) to New York (JFK) / Philippine Airlines / 8,520 miles / Airbus A350-900
- Singapore (SIN) to San Francisco (SFO) / Singapore Airlines & United Airlines / 8,446 miles / Airbus A350-900 & Boeing 787-9
- Atlanta (ATL) to Johannesburg (JNB) / Delta / 8,439 miles / Airbus A350-900
- Mumbai (BOM) to San Francisco (SFO) / Air India / 8,406 miles / Boeing 777-200LR
- Dubai (DXB) to Los Angeles (LAX) / Emirates / 8,339 miles / Airbus A380
- Jeddah (JED) to Los Angeles (LAX) / Saudia / 8,332 miles / Boeing 777-300ER
- Doha (DOH) to Los Angeles (LAX) / Qatar Airways / 8,306 miles / Airbus A350-1000

I intentionally left out the flight times, since they fluctuate throughout the year due to winds. Furthermore, some airlines pad their schedules more than others (in order to create artificial on-time arrivals). All 20 of these flights are blocked anywhere between 15hr5min and 18hr50min.
The one asterisk I should add is that the Shenzhen to Mexico City flight only operates nonstop in the eastbound direction. It’s so long that in the westbound direction a refueling stop is needed in Tijuana.
Below is a map with all the routes, which is quite cluttered, as you can see.
What record-breaking flights are on the horizon?
A majority of the world’s longest flights haven’t been around for that long, which raises the question of what else might be on the horizon. Purely in terms of record-breaking flights, that’s probably an area where Qantas will continue to lead the way.
The oneworld carrier is working on its “Project Sunrise” concept, whereby we’ll see nonstop flights from Melbourne and Sydney to London and New York using special Airbus A350-1000s. We have seen some delays with this, and at this point, the expectation is that these flights will launch in the first half of 2027. All four of those routes will be longer than any existing routes by a pretty healthy margin.
Those aren’t the only Qantas flights that might be on the horizon that would make the “top 20” list. Pre-pandemic, Qantas planned to launch a Brisbane to Chicago flight, which would cover a distance of 8,916 miles. It’s anyone’s guess if this flight ends up launching eventually, but it’s another potential ultra long haul route.
Bottom line
We’re seeing more ultra long haul flights than ever before, with so many new routes having been launched in the past decade. This is thanks to how amazing the Airbus A350 and Boeing 787 are. Compared to previous generation aircraft, these planes are low capacity, long range, and fuel efficient.
While these marathon flights are great for those traveling in a premium cabin, I can’t imagine doing a nonstop flight like this in economy. In those situations I feel like I’d rather break up the journey than fly nonstop. Heck, even in business class I feel like some of these flights are too long.
Which ultra long haul flight do you find most interesting, and what do you think we’ll see added next?
My wife & I just did #1 (SIN - JFK) in January. Great airline & great flight, 16.5 hours.
When I flew EWR-SIN actual flown was over 10000 miles and almost 19 hours.
I "get" to do #15 after a trip to MLE. First one this long. (that's what she said)
All my others have been short haul, 8 and 9 hours.
Haven't done any of these but have flown one that's almost certainly in the 21-30 range of this list: YYZ to HKG. Absolute marathon of a flight.
These flights are too long period. Doesn’t matter if it’s in Y, J or F.
My max for a direct flight in J/F is 8 hours. Beyond that I try to break it up.
8 hours? Short haul! Try crossing the Pacific, you can do that from the US to Australia in two hops, but one of them is at least 10 hours. (I've flown no 5 [in PE] and 13 [in Y], both doable.)
That's why Americans feel like they're the center of the universe, except they couldn't even make it across the pacific.
There are others that you did not report on....but this could be a paid article
Rather than making vitriolic comments, maybe you should try suggest what is missing.
The Longest Flight has to be the "Air India" Flight. even a 10 hour Flight feels like 20 Hrs long. can you imagine sitting next to a Garlic/Ginger Curry Breath for 15 Hours? Not only that most have stomach issues also.
Sat in SIA’s PEY cabin now on our way to Newark ..
If you can’t handle an ULH flight, you can’t call yourself a travel enthusiast!
Rolls eyes.
Ho,
The problem with SQ ULR is their J sucks, and their PE sucks.
If only they could put the 787 or A380 J seats instead. Looking forward to their new J.
Perth to Rome at 8332 miles should also be on here, unless you don't count seasonal flights (it operates only during the Northern summer).
Both MAA and HYD to SFO should likely happen in the next 3-5 years
To be honest, years ago I thought I would never fly one of these but being based in Australia, more often than not, they are the best option and I have flown many of these ex Asia, NZ and Australia. Sounds extreme but 18 hours doesn't really feel any worse than 12 hours especially for those of us where flights of minimum 8 hours are the norm. Plus unless the stopover is more than a...
To be honest, years ago I thought I would never fly one of these but being based in Australia, more often than not, they are the best option and I have flown many of these ex Asia, NZ and Australia. Sounds extreme but 18 hours doesn't really feel any worse than 12 hours especially for those of us where flights of minimum 8 hours are the norm. Plus unless the stopover is more than a day or two, the effort of dealing with bags, immigration, more check ins etc just doesn't outweigh the one flight and it's done. I definitely don't want to do a connecting flight at the end of that long haul flight although I have had to do it many times especially if it involves immigration, terminal changes & downsizing to a smaller plane, looking at you LAX & DFW, ugh!
A couple of years ago when AA started long haul Auckland to NYC, I was on one of their first flights in both directions and it was very clear that none of the crew had ever experienced such long haul flights. They were completely out of their depth from every aspect & I felt sorry for them. I'm sure they learned quickly especially as the passengers pretty much knew how to handle the eating, sleeping, moving routines necessary to get through.
AA never flew NYC-AKL.nice try.
I think she meant Air New Zealand, the 'couple of years ago' part matches that. (QF also flies the route so it is possible that AA had a codeshare on theirs.)
It's a fun quirk of geography that IAH-SYD is longer than DFW-SYD while SFO-SYD is shorter than LAX-SYD.
DFW is actually in the northwest of IAH that's why DFW-SYD is shorter than IAH-SYD
Except dfw - syd is not shorter vs Iah- syd
SFO is also to the NW of lax but shorter distance to syd
But DFW to SYD is shorter than IAH to SYD as Jane said in her first post. A further quirk, YVR-SYD is shorter than LAX-SYD.
This list is incorrect! It doesn't include BOS-LAX in economy with the person in front of you fully reclined. I know they claim it's ~6h but it's obviously 16h and 10,000 miles... right?!
If we're playing that game, I'd personally suggest the ride to hell and back on Jetstar from HNL to MEL is worse. But $146 one way is tough to beat
Don’t forget the Eurowings a320 from BER to DXB!
or dear god... YHZ-BCN. I get that the Canadians need to fly those MAXes somewhere other than RSW due to demand but damn... no thanks
It seems weird that Singapore to JFK is 14 miles further away than Newark (as the crow flies). You’d think over that distance they’d almost be the same (or is jfk directly past Newark)?
Weird indeed.
You'd think over that distance the world would be flat?
Just to add, Turkish has apparently ordered some -1000s for flights down under.
And it's just a matter of when, not if until we see flights from Asia to Florida.
P.s. thanks to whomever is liking my contributions on here lol
Wonder if they'll stretch them all the way to AKL. Would take the crown from Qantas' flagship route to LHR from SYD.
Mexico City => Shenzhen likely requires a fuel stop b/c of altitude in the former, even MEX => ICN, PVG back in the day needed to stop in Tijuana or Monterey for refueling. So no way would MEX-SZX ever make it
Correct, that flight makes a Tijuana stop on the return. It's nonstop going eastbound to Mexico City.
In my earlier comment I actually mentioned SZX-MEX flight only operates nonstop eastbound, for westbound CZ do a refueling stop in TIJ, however no passenger can board at TIJ for this flight unlike HU's PEK-TIJ-MEX where passenger can only fly PEK-TIJ segment without go all the way to MEX
Minor issue on the GC Map: it is showing JED-DOH rather than the intended JED-LAX.
Sending this comment from seat 11k on SQ21 EWR-SIN
Then you're at 35,000 feet having just passed Newfoundland with a UPS 767 in front of you :D
Thanks. The free WiFi up here is great, just had some nice 2018 Piper-Heidsieck!
Cheers, mate. Enjoy the satays up there. As Ben would say, Yum, yum, yum.
And another fyi, the closest a/c on your left would be an EK 77L from YUL and on your right, an AC to LHR from Halifax just in case you're wondering who's around you at the moment. ;)
It's also worth noting that the flight times vary widely for the reasons mentioned, but also that due to Russian overflight restrictions, there are probably some theoretically much shorter flights that may actually have longer flying times right now. United's DEL-EWR flight has a scheduled block time of around 18 hours for example.
CZ's SZX-MEX flight only operates as nonstop for SZX-MEX direction, on the return they stop in TIJ to refuel as MEX's elevation too high for 359 take off at MTOW.
Was the Newark to Bangkok on Thai airways the longest flight ever ?
It was from JFK rather than Newark and SQ started EWR service much earlier IIRC.
I think you mean similar capacity as I don't think the A359/K is lower in capacity than its predecessor or even its competitor on the B team. ;)
I flew SIN-EWR in business last month (with two kids under 5) and surprisingly didn't think it was "too long". I had hemmed and hawwed over nonstop vs breaking it up... eventually chose a 3hr layover in IST on the way to Asia and the nonstop on the way back to NYC and I'm not sure which I preferred to be honest.
I actually really like the long SIN-JFK/EWR flights in business. There's plenty of time for both working and reading or watching a movie or two or three, AND getting a good 5 or 6 hours of solid sleep. No getting woken up early because we're about to land, and the FAs are very good about letting you eat on your schedule, not theirs. I just need white noise (I use Ozlo SleepBuds), an eye mask,...

No getting woken up early because we're about to land, and the FAs are very good about letting you eat on your schedule, not theirs. I just need white noise (I use Ozlo SleepBuds), an eye mask, a small portable fan, and comfortable clothes and I sleep really well on those flights.
And the SQ service is just delightful.
Me too! We did the nonstop EWR to SIN in business on the way over and the SIN-FRA-JFK in business on the way back. The stretch and short time in the lounge in FRA was actually kind of nice. Also, Ben's map is interesting in that I think that was the path of EWR-SIN back when Russian airspace was available, but our flight did not go polar at all but went straight through Europe, the...

Also, Ben's map is interesting in that I think that was the path of EWR-SIN back when Russian airspace was available, but our flight did not go polar at all but went straight through Europe, the Middle East, and India enroute to Singapore, and the screen at our seat showed 17,127km, or 10,642 miles.
Years ago, CXs JFK-HKG service was in the top 5 if not 3 longest flights in the world. Now it's just another long-haul flight.
Time certainly flies (excuse the pun)
It's funny I was thinking the same - there's really been two rounds of evolution to this list. First was the rise of the ME3 where a ton of routes started from DFW/IAH/SFO/LAX to AUH/DXB/DOH/JED.
Then, as B789s and A350s started becoming ever more higher performing, a second wave came of more these point to point routes.
I distinctly remember a few years back (probably 7-8 years back) the various Middle East routes to...

I distinctly remember a few years back (probably 7-8 years back) the various Middle East routes to LAX were all way higher up the list, and now they're barely in the Top-20.
