The World’s 15 Longest Flights (2021)

Filed Under: Travel

Lately we’ve seen a trend whereby airlines have added an incredible number of new ultra long haul flights. This is a reversal of a previous trend, because prior to a few years ago we saw fewer and fewer long flights introduced.

When you look at the list now, a majority of these flights may have been unfathomable several years back, but are now thriving.

Why Ultra Long Haul Flights Are More Practical Than Ever

What makes ultra long haul flying more sustainable than in the past? A couple of factors:

  • The new aircraft technology we’ve seen, especially with the Airbus A350 and Boeing 787; these planes are fuel efficient and relatively low capacity (at least compared to the 747), and as a result are able to operate long flights in a profitable manner
  • Oil prices are still fairly low (though also volatile), and there’s strong global demand for nonstop flights between business hubs

The World’s 15 Longest Flights As Of April 2021

I figured it would be fun to look at the world’s 15 longest flights, given how much the list has changed lately. I’m going off of distance here, 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.

What’s pretty amazing to me is that all 15 of these flights are over 8,200 miles, which is a long way to go nonstop.

So, 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):

  1. Newark to Singapore / Singapore / 9,534 miles / Airbus A350-900ULR
  2. Auckland to Doha / Qatar / 9,032 miles / Boeing 777-200LR
  3. Perth to London / Qantas / 9,010 miles / Boeing 787-9
  4. Auckland to Dubai / Emirates / 8,824 miles / Airbus A380
  5. Los Angeles to Singapore / Singapore / 8,770 miles / Airbus A350-900ULR
  6. Houston to Sydney / United / 8,596 miles / Boeing 787-9
  7. Dallas to Sydney / Qantas / 8,578 miles / Airbus A380
  8. New York to Manila / Philippine Airlines / 8,520 miles / Airbus A350-900
  9. San Francisco to Singapore / Singapore & United / 8,446 miles / Airbus A350-900 & Boeing 787-9
  10. Johannesburg to Atlanta / Delta / 8,439 miles / Boeing 777-200LR
  11. Abu Dhabi to Los Angeles / Etihad / 8,390 miles / Boeing 777-300ER
  12. Dubai to Los Angeles / Emirates / 8,339 miles / Airbus A380
  13. Jeddah to Los Angeles/ Saudia / 8,332 miles / Boeing 777-300ER
  14. Doha to Los Angeles / Qatar / 8,306 miles / Boeing 777-200LR
  15. Toronto to Manila / Philippine Airlines / 8,221 miles / Airbus A350-900

Singapore Airlines A350

I intentionally left out the flight time, since they fluctuate throughout the year due to winds. All 15 of these flights are blocked anywhere between 15hr and 18hr45min.

I’m leaving out those flight times not just because the seasonal fluctuations, but also because some airlines pad their schedules more than others (in order to create artificial on-time arrivals), so I don’t want to give them too much credit there.

Here’s a map with all the routes, which is quite cluttered, as you can see:

Just to further illustrate how much more popular ultra long haul flights have become, only six of the above 15 flights have been operating prior to 2016, meaning that nine of the above routes have been launched within the past few years.

Even more impressive, the world’s six longest flights, and for that matter eight of the world’s nine longest flights, have been launched since 2016.

What Record-Breaking Flights Are On The Horizon?

Two of the world’s three longest flights were launched in 2018, which raises the question of what other record-breaking flights might be on the horizon.

Well, at the moment there are two more flights that have been confirmed and that will be joining the list soon.

Qantas will begin flying nonstop between Brisbane and Chicago as of April 2020. That flight will cover a distance of 8,916 miles, so it will be the world’s fourth longest flight, right behind Qantas’ Perth to London flight.

Qantas 787

On top of that, Air New Zealand will begin flying nonstop between Auckland and Newark and Chicago as of October 2020. That flight will cover a distance of 8,810 miles, so it will be the world’s sixth longest flight, right behind Emirates’ Auckland to Dubai route.

There are some other interesting flights that have either been launched or are on the horizon, but that we can’t add to the list yet:

Bamboo Airways 787

Beyond that, perhaps the biggest thing on the horizon is Qantas’ “Project Sunrise,” where they hope to fly nonstop from Sydney and Melbourne to London and New York. Qantas has selected the A350-1000 for these routes, and plans on launching the routes by early 2023.

Longest Flight Summary

It’s exciting to see the number of new ultra long haul flights that are being added by airlines, thanks to new aircraft, like the 787 and A350.

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.

It’s especially encouraging how many of the longest flights have been added in the past few years. Unfortunately at this point there’s not much else in the pipeline with current plane technology.

The next big groundbreaking flight will likely be when Qantas announces their Project Sunrise flights.

What ultra long haul routes do you think we’ll see introduced next?

  1. Another interesting trend with this is that none of these routes (except dallas a380) have first class. I would have thought there’d be passengers willing to pay an extra premium for even more space over business for such a long flight. At least more demand than anyone in economy willing to pay the premium for non stop in

  2. I wouldn’t fly any of these flights in economy. Hats off and respect to those who have the endurance that can, for whatever reason they are flying those routes in economy.

  3. What about Air India Delhi to SFO via pacific and SFO to Delhi via atlantic?
    Both routes have enough mileage to fall within the top 15 flights

  4. @ Mehul Shah — This is based on the direct air distance between origin and destination (since no flight ever takes exactly the same path twice). The San Francisco to Delhi flight has a direct air distance of 7,706 miles, so doesn’t quite make the list.

  5. Though what you aren’t forgetting is that these flights are very popular with young kid families as they don’t Ahventie to drag their kids through some forge in airport and the kids just sleep and watch tv and have plenty of room cause they are so small

  6. I fly long routes, but since using redeemed miles for economy seats, the flights sometimes take strange and complicated routes. Such as flying from Marakesh to Capetown via Lisbon and Munich…or my flight from Eastern Island to Galapagos, via Santiago, Quito. I got a DVT on a flight from LAX to Cairo last year, and that was a direct flight. Two weeks later, on a flight back from Istanbul, I got stuck in the middle seat because of a full flight. Fortunately I was on blood thinners on the way back. I’m flying to Cochin, India in several days, LAX, Frankfurt, Delhi, Cochin. I’m getting mentally prepared.

  7. A flight that I take often is BR51, IAH-TPE. This is typically just over ~8000 miles but because of the winds the flight can easily take over 16:30hrs, especially in the winter months. Great service and seat makes this flight quite enjoyable, and now that UA opened their Polaris Lounge at IAH, it’s even better. I just hope IAH gets more flights to Asia ( fingers crossed for HKG).

  8. @ Tom — I doubt Delta will actually launch service to India anytime soon (I think they were bluffing). An Atlanta to Mumbai flight would be just over 8,500 miles, so would make the list. A New York to Mumbai flight wouldn’t make the list, however.

  9. As I always say, the only way to truly appreciate flying premium cabins is to fly in economy. 😉
    I think flying ultra-longhaul in economy is fine as long as the seat next to you is empty or you get an empty row. Flying in economy in a full full flight over 15 hours is just miserable.
    I was hoping Air New Zealand would fly AKL-EWR nonstop.

  10. I don’t have any vision of the ultra long haul future but as a regular long haul passenger I avoid these endlessly long marathon flights. If I’m dealing with one of these routes, I schedule an overnight hotel stopover outbound to keep myself physically well and avoid major jet lag. A few years ago, I scheduled two nights in Paris enroute from San Diego to Israel for a ten day vacation. Hats off to those who can do these ultra long hauls, unfortunately I’m not one who ever cares do it again.

  11. I flew #10 (ATL-JNB) on SA back when it was #1. It was on a 747 and they didn’t fill all economy seats due to weight limits. On the way back, it made a refueling stop in SID (Cape Verde).

  12. Will fly in a couple of weeks Dubai to Dallas which is 8,024 miles and 16 hours in the air. I think it would make it to the first twenty longest flights. I’m already scared of such a long flight and 10 hours time difference.

  13. I took United’s LAX-SIN Economy back in the summer. Unless they got up only when I got up, the person in the middle seat next to me never got up the whole flight.

  14. Some other rumors I’ve heard are SFO-BKK, MEL/SYD-IST, ATL-SYD (Unlikely), NRT-JNB, MNL-ORD, DXB-EZE, SFO and LAX-HAN and SGN, SFO-HYD, SVO-EZE, and IAH/IAD-JNB. Majority of these seem very unlikely but the SFO-BKK and NRT-JNB and Houston/Washington to JNB do actually look intriguing…

  15. Perhaps you already noted this elsewhere on OMAT, but what website do you use to review flight distances and create the map graphic you posted?

  16. Have flown some of these flights in economy – 777 nine abreast (Delta) & A380 were fine . 787 was dreadful .

  17. Hi Lucky, why is it just one direction? For instance, Newark to Singapore instead of between Newark and Singapore. I assumed you used Great Circle Mapper for distance and both directions show the same.

  18. @Will – it’ll be nice to see NRT-JNB happening, but there hardly is any demand. The Japanese carriers will definitely not going to make it, and SAA may be if they make JNB a good transit hub for GRU or GIG, but then with current financial situation I doubt they’ll ever consider before starting other Asian routes other than existing HKG.

  19. It still makes me smile that despite all the new technology – 5 of these flights are operated by a 777 which have been around for ever. Clearly technology has helped change the ultra long haul possibilities, however it looks like the 777 has had this ability for a long time prior to the new generation of 787s and A350s but the airlines were not as keen

  20. Emirates operates an A380 on the DXB-LAX route, not a 777 (thank goodness!). We’re looking forward to getting 8 hours of sleep and 8 hours of food and bar time in business class later this year!

  21. I have done a couple of ULHs in economy/premium economy: EWR-SIN and LAX-BKK (Thai used to operate that relatively little known route). In both cases I also had 4-6 hour connections in Asia.

    Once I flew Cape Town-London-Toronto. I had a long layover at LHR, and they actually let me enter another terminal just to visit a lounge 🙂

  22. I flew from DXB to DFW when Emirates first started flying there and it was a 16 hour haul there and 14 hours back.

  23. I fly MEL (Australia) to LAX in economy. It’s only ok if I’m flying without my kids and on a flight with empty seats. Plus, on flights to the US, flight attendants go around reminding passengers not to congregate in the toilet/ food areas because of security. Apparently they think we are plotting terrorism when we’re actually trying to prevent dvt and minimise back pain.
    Long hauls flights really should be required to provide more health / comfort amenities for passengers.
    I end up spending my first 2-3 days after arrival trying to reduce flight-induced pain.

  24. Why would Sydney-Houston be a longer flight than Sydney-DFW? Granted Houston is 50 miles East of DFW, but DFW is 200 miles further North.

  25. I have done AKL to DOH (Qatar) and AKL to DXB (Emirates) return via Europe.. Total flight times always 22-24 hours, 90-120 min lay over each time.
    Completed both in Economy and business. A380 and 777.
    I have to say the A380 business class is the perfect plane for ultra long haul. The 777 is good (better in the new pod) that Qatar offer but lacks the space to move about.
    Its a tragedy that we are seeing the demise of the A380 already… Just perfect for the space and enjoying the experience.
    I will complete the top 5 trips by next year!

  26. Will soon also experience same in case my travel case appear shorter.
    I think I could also go for A380 than 777boeng it would be moverous for the first time over 18hours in the air. that’s wow

  27. I schedule a connection for any flight longer than 11-12 hours. Even in business class, that is long enough for any one flight.

  28. I recently nearly took United’s – Houston Sydney both ways using United saver miles (while those deals still exist) then balked last minute and switched to Air New Zealand’s biz outbound and Qantas (CHC-BNE- LAX using Alaskan miles) biz inbound. So glad I did, both have immeasurably better products on the 300-ER (wonderful bed) and 787-9 (awesome hard and soft product) than the antiquated United 787. So weird United didn’t move their longest flights to the new Polaris hard product first?? I guess they knew they would get the revenue customers likes United’s Mr Ga-jillion miler. Additionally Houston’s Polaris lounge is nice but is small and gets very busy. Soon it will just be another Club to avoid…come on United move all your fleet to the new Polaris hard product while Saver awards exist…

  29. I don’t know it is exciting or excruciating for me to be flying SQ22 soon, on Sept 24 from SIN to EWR, in premium economy, not business. I do hope to send a positive report after my flight, and that’s one Aviation Geek wishlist item ticked off. Departing on SQ21 on Oct 8, so double the fun I suppose!

  30. In terms of miles Dxb-Dfw being an inch above 8000 miles doesn’t qualify within the top 15 although outbound it’s a 16 hours flight, but I think time flight should count more than distance when we consider the longest. No?

  31. @aaron I agree. These flights would be brutal in Y, especially if full. Flew EWR-SIN in premium Y and it was bearable as I had a solo window seat.

  32. Could the DOH-GRU count? Because of the restrictions Qatar Airways has, the flight is ~8300 miles even though direct would only be ~7350 miles.

  33. whilst i find these flights are fascinating from an avgeek perspective – we have to remember that they represent a tiny fraction of flights flown – they are truly niche !

    and they are also truly horrendous from an environmental perspective – carrying all that fuel for ultra long haul is absolutely ruinous.

  34. Why would Sydney-Houston be a longer flight than Sydney-DFW? Granted Houston is 50 miles East of DFW, but DFW is 200 miles further North.

    For the same reason that SYD-SFO is shorter that SYD-LAX. The earth is round.

  35. @Lucky — is there a way to follow threads such as this one *without* leaving an actual “reply”? Do we just leave the “reply” box empty and just register our name/email to get email notifications of new comments posted by others?

  36. I did SQ EWR-SIN in J had a couple hours in the lounge in SIN and then took another overnight flight SIN-SYD in J. It was a lot of flying. EWR-SIN in J is bearable, but not sure if I would do it again. I would never do it in an economy seat though.

  37. @Benz: Did the person who never got up during your 16 hour flight get up when the flight was over? Did you check for a pulse?

  38. I remember doing #10 before non-stop was possible. Two options were stopovers either in Frankfurt or Miami. The LA>SIN meant a fuel stop in Inchon, which was still a restricted airbase in 1998,

  39. My young family of 4 with a 2-year old and 3-month old flew DFW->SYD recently in econ. We booked this during one of the fare wars, so it was dirt cheap. I didn’t know this at the time, but this route is payload restricted (I think?) and economy cabin was quite empty. We used probably 10 seats collectively during the flight and no one batted an eye. It also helps that there are stairs to get the kids’ energy out. Wouldn’t hesitate to fly again if the price is right!

    Half the passengers on board were young families like us so may not be the thing for you if you can’t stomach the idea of sitting next to struggling kids, though…

  40. notable that only one European city features in the list … and not a single european airline.

    is this indicative of a lack of ambition of european aviation … or a result of a focus on profitable routes rather than prestige routes ?!

  41. I’ve done DOH-AKL in J twice in the past 3 months. Very pleasant flight, I slept most of the way. It’s the Q-suite with the door, so it was very easy for me to sleep. I arrived quite rested.

  42. Here are a few possible:

    IAD-HKG: 8153 miles (is this run now?)
    IAD-SYD: 9743 miles (after the Project Sunrise flights are sorted out)
    ORD-SYD: 9232 miles

  43. I did number 4, AKL to DXB, in business with EK in mid 2016. A very pleasant night flight it was, a 777 (can’t remember which version) in those days and it had a full first class! I had a window seat with no one next to me, drinks before dinner, dinner, then a movie and a full 8-9 hours sleep before breakfast prior to arriving in Dubai. The 15 hours or so passed by like a charm and I arrived quite alert in DXB in time for a connecting flight to BRU. Though I must say I slept very well the next night in Brussels as the jet lag hit!

  44. @Mehul Shah: No it doesn’t cut it, not even the longer EWR to BOM route, still less than 7,800 mi.

    @TOM: The new JFK to BOM route by Delta this December will be almost similar – less than 7,800 mi, as well.

  45. Lol at anyone that thinks SYD-DFW is shorter than SYD-IAH. As a PHd in mathematics and spacial relationships, this is a pipedream concocted in the minds of marketing departments of Star Alliance executives. And it’s not physically possible given current technologies in commercial airlines. The only way this is humanly feasible is if the IAH-SYD flight is flying a type if plane that is currently unknown to the general public. Some of you need to do more research before you post.

  46. Lol at anyone that thinks SYD-DFW is shorter than SYD-IAH.

  47. @Elite White Liberal — “Lol at anyone that thinks SYD-DFW is shorter than SYD-IAH. … it’s not physically possible given current technologies in commercial airlines … Some of you need to do more research before you post.” —

    So just out of curiosity, I looked up *Flight* (*not* Earth surface point-to-point) distances on and got the following results —

    1. Between SYD and IAH — 8596 miles
    2. Between SYD and DFW — 8578 miles

    Airliners travel within pre-determined flight “corridors” so it’s *not* just surface point-to-point distances, as might be commonly believed!

  48. The 2020 list is missing LATAM’s GRU-TLV, which is 8200 miles as the crow flies, but which has taken several hundred mile detours to avoid overflying Sudan, which did not allow TLV flights to overfly their territory and is blocked at 15:30 (and about the same distance flown as DXB-PTY). Last week Sudan announced that they would initiate diplomatic relations with Israel and allow overflights, and the flight will soon be re-blocked at about 14:00.

  49. Also on the horizon is American’s to-be-launched SEA-BLR, although it would be a few flights short of making this list since it’d be 8078 miles

  50. Lucky,

    You are also missing Air New Zealand’s new flight from EWR-AKL starting in I believe October 2020. That will be 8810 miles which would be #6 after the new Qantas service mentioned in the article.

  51. @elite white liberal
    @coastal elitist

    Everyone here will scoff at your claim of holding a PhD in maths and ‘spacial relationships’. Why? Because posters love to throw around claims of being…..wait for it…..PhD holders, pilots, lawyers, medical doctors and billionaires. It’s pretty much standard play here, and never fails to elicit a knowing smile/smirk and eye roll in our readers.

    That said. I tend to believe your claim to hold some sort of ‘PhD’, from some sort of ‘university’. Why? Because you seem to have the ideal prerequisites: you come off as very blinkered, narrow-minded, and you certainly don’t make sense to the ‘average’ person. 😉

    Wishing you well in your academic ‘accomplishment’.

  52. “ If I’ve never seen such riches, I can live with being poor “ living in UK. Working in Australia- flying economy 🙂

  53. “is this indicative of a lack of ambition of european aviation … or a result of a focus on profitable routes rather than prestige routes ?!”

    I suspect it may be topology. LHR-SYD is 10,569… But LHR-NRT is 5,956; LHR-CPT is 6,017; LHR-EZE is 6,915; LHR-LAX is 5,440.

    Basically, Europe is more central.

  54. It’s interesting that all but 3 flights on the list are to/from North America. Says something about world geography.

  55. I miss the old LAX-BKK non-stop flights.

    It was top 5 (IIRC) back in its day, but I don’t think it would break the top 15 these days.

  56. I am scheduled to do EWRSIN in SQ Premium Economy (SQ21/SQ22) in April on my way to a meeting in SYD, as I chase the SQ Gold status and dumping UA, and hope the nCoV-19 is not going to force me to cancel the trip! Same with my planned JFK-FCO-KHI and back next month on LH and TK that I credit to SQ.

  57. My wife and I have flown DFW to Hong Kong (16.5 hours), LAX to Doha (16+ hours) and Newark to Singapore in economy (We work for an NGO). I enjoy the long flight, plenty of time to sleep watch movies, get work done. I’m 5’8″ (173 cm) and fit fine in economy seats.
    On our 25th anniversary we traveled around the world mostly in business class using miles and upgrades (Newark to Singapore, then to Delhi and then Helsinki then Miami and finally Buenos Aires, Argentina). I remember clearly my feelings on that first flight in business class when I flattened my seat out, covered myself with bedding after a tastier than normal in-flight meal… i was mildly disappointed. I thought, this is kind of cramped and not that comfortable, and I told myself, “Remember this if you ever consider paying 2 – 4 times more for a better location on the plane… not worth it.” That’s my take on it from the economy section 🙂

  58. Interesting how none of the US to China flights are listed. I wonder if this is because they have temporarily stopped service or if they don’t qualify in the longest flights anymore.

  59. It’s crazy that ATL-JNB is almost 500 miles further than JFK-JNB. Thought you left it off the list but that’s what a globe will do apparently lol.

  60. Can you please define “artificial on-time arrival”? How does it differ from a non-artificial one? Can you please let us know out of 100 random on-time arrivals, how many are artificial and how many are not?

  61. Interesting you eliminated the YYZ designation from your map. You kept the line but didn’t show the origin. Not surprising. Most Americans have no idea where Canada is and don’t care.

  62. JFK-HKG is 8061 miles. Doesn’t make it. ATL-HKG is 8389, and would go into slot #12. HKG-MIA is 8982, and would go into slot #4. But I don’t see Delta or AA going for either one. {shrug}

  63. How about Delta 8875, a westward 777-200LR from Mumbai (BOM), to ATL, 16h 53m total travel time over a cool 8500 miles. It must be fairly new route since DAL 200/201 is on hiatus.

  64. The new Bangalore to San Francisco flight (Air India) would definitely be on that list, although it’s a very new route it’s the longest for any indian airline and any flight to India ever.

  65. In this list one important flight is missing i.e. is
    Air India’s longest direct flight from San Francisco to Bengaluru .
    The direct distance between the two cities at opposite ends of the world is 13,993 km or 8,694.85miles with a time zone change of around 13.5 hours.
    Even on 11th Jan 2021 this flight has travelled with an all-woman cockpit crew.
