Key takeaways

  • The 787-10 is the longest Dreamliner version: 68.3 m long, around 5.5 m longer than the 787-9, with the same 60.1 m wingspan.
  • Fastest way to identify the family: serrated engine trailing edges plus wingtips without winglets.
  • You determine the variant by its proportions and most reliably by registration or type code B78X.
  • It is built only in North Charleston: The center fuselage sections are too large to transport to the Everett factory.
  • In the DACH region it is a visitor: Lufthansa, Swiss and Austrian don’t fly the 787-10; you’ll meet it with foreign airlines or at Amsterdam with KLM.

Identifying features

Is this really the aircraft type in front of you?

Check off everything that applies to the aircraft you are looking at.

  • Very long, slender fuselage – relative to the wing, the 787-10 looks much more stretched than the 787-8 and 787-9
  • Serrated trailing edges on the engine nacelles (chevrons) – the trademark of the whole 787 family
  • Wing without an add-on winglet, the tips sweep back at an angle (raked wingtips)
  • Smooth, rounded nose with just four large cockpit windows, no dark mask
  • Main landing gear with four wheels per leg – the A350-1000 and 777 have six
  • Strong upward wing flex in the climb, typical of the Dreamliner’s carbon-fiber wing

Updated: October 2026 – A Dreamliner taxis to the runway, the engines have the typical serrations at the end, the wings end without winglets. But the fuselage looks unusually long, almost as if someone had stretched the aircraft lengthwise: then you’re very likely looking at a Boeing 787-10. This page shows you how to tell it from the 787-9, A350-1000 and 777-300ER and where your best chances are in Europe.

What is the Boeing 787-10?

The 787-10 is the third and longest version of the Dreamliner. Boeing derived it from the 787-9 and stretched the fuselage by around 5.5 meters, split between a plug ahead of the wing and one behind it. Wing, cockpit and engine options stayed the same. According to Boeing, a two-class cabin holds 300 to 375 seats, and the wingspan is 60.1 meters, as on its sisters.

The idea behind it: more seats and cargo per flight, in exchange for somewhat less range than the 787-9. The 787-10 is thus tailored for medium long-haul routes, typically flights within Asia, across the Atlantic or to the Middle East. For ultra-long-haul, airlines tend to reach for the 787-9. Boeing’s current website gives a range of up to 7,500 nautical miles, around 13,890 kilometers; earlier manufacturer figures were significantly lower. What an individual airline makes of that depends heavily on cabin and loading.

The program was launched in June 2013 at the Paris Air Show, with Singapore Airlines as launch customer. The roll-out followed in February 2017, the first flight on March 31, 2017 in North Charleston. On March 25, 2018, Boeing handed the first aircraft to Singapore Airlines, and in early April 2018 it entered scheduled service. One peculiarity: the 787-10 was built only in North Charleston, South Carolina from the start, because its center fuselage sections are too large to transport to the Everett factory. Since 2021, Boeing has assembled all Dreamliners there. You’ll find more on the manufacturer on the page about Boeing.

The three steps to a reliable ID

With the 787-10, you first identify the family and then the variant. The family is easy; the variant takes a practiced eye or the registration.

Look at the engines

The trailing edges of the engine nacelles are serrated like a saw blade. These chevrons reduce noise and are a strong indicator of the 787 on widebody jets. The 747-8 has them too, but you can tell that one apart by its four engines alone.

Check wingtips and nose

No add-on winglet; the tip sweeps back at an angle. The nose is smooth and round, with four large cockpit windows and no dark mask like on the A350.

Judge the proportions

If the fuselage looks very long relative to the wing and the wing sits visually almost in the middle, that points strongly to the -10. On the compact 787-8, the wing feels like it sits further forward and the fuselage looks stubby.

The proportions are a good hint but not proof – perspective and focal length distort lengths quickly. In the end, the registration confirms the variant. How to read registrations is explained in the guide Understanding aircraft registrations.

Practical tip: count the windows

If you have a sharp side profile, compare the row of windows ahead of the wing with the one behind the wing. On the 787-10, both sections are visibly longer than on the -9. With Planetrack, you post every sighting with registration and aircraft type – that way you train your eye with every aircraft. Planetrack is launching soon – secure your spot on the waitlist now.

787-8, 787-9 or 787-10?

All three versions share the 60.1-meter wingspan and the basic layout. The decisive difference is length.

Feature 787-8 787-9 787-10
ICAO type designator B788 B789 B78X
Length 56.7 m 62.8 m 68.3 m
Wingspan 60.1 m 60.1 m 60.1 m
Height 16.9 m 17.0 m 17.0 m
Seats (2 classes, Boeing) 200–275 250–325 300–375
Range (Boeing, up to) approx. 14,820 km approx. 15,370 km approx. 13,890 km

Interesting for spotters: on the 787-8, the wingspan is greater than the fuselage length; on the 787-10, it’s the other way around – it is over eight meters longer than its wings are wide. It is exactly this impression of a “too long” fuselage that is the identifying feature in the field. We cover the middle sister on the page about the Boeing 787-9 and the compact original version on the page about the Boeing 787-8.

Technically, Boeing equipped the 787-10 with an adapted main landing gear that allows rotation over the rear wheels at takeoff, reducing the risk of a tail strike. From the outside this is barely noticeable; the wheel count stays at four per leg.

787-10, A350-1000 or 777-300ER?

The 787-10 plays in the same league as the big twinjets from Airbus and Boeing. From a distance, you’re most likely to confuse it with the A350-1000 or the 777-300ER. The finder helps narrow it down.

Quick ID: long widebody twin

Three questions, one assessment. The registration has the final word.

Likely

Boeing 787, with a very long fuselage the 787-10

Chevrons and a four-wheel landing gear fit the 787 family. If the fuselage looks conspicuously long relative to the wing, it’s the -10. Confirm it via the registration or the code B78X.

Likely

Airbus A350-1000

Mask at the cockpit, curved wingtips, smooth engines and six wheels per leg are the look of the big A350.

Likely

Boeing 777-300ER

Six-wheel landing gear, huge GE90 nacelles without serrations and a blade-flattened tail point to the 77W.

At 73.78 meters, the Airbus A350-1000 is around five and a half meters longer than the 787-10 and has a much larger wing. The Boeing 777-300ER is yet another size up, at almost 74 meters long with a wingspan of just under 65 meters. Next to both, the 787-10 looks slimmer and more delicate. The Airbus A330-900 can also look similar from a distance, but it carries curved sharklets on the wingtips and a cockpit mask. The guide Telling Airbus and Boeing apart collects general tricks for such cases.

Who flies the 787-10?

The largest fleets are in Asia, North America and the Gulf. Operators include Singapore Airlines as launch customer, United Airlines, Korean Air, ANA, Saudia and Etihad Airways. In Europe, there are two names:

  • KLM was the first European airline with the 787-10 in June 2019. The Dutch carrier has gradually expanded its fleet since then and operates the type from its hub at Amsterdam Schiphol.
  • British Airways took delivery of its first 787-10, registration G-ZBLA, in June 2020 and ordered twelve aircraft in total. Its home is London Heathrow.

Important for German, Austrian and Swiss spotters: Lufthansa operates the 787-9, not the -10. Swiss and Austrian Airlines don’t have a 787-10 in their fleets either. In the DACH region, the type is therefore always a visitor of foreign airlines. Your chances come mainly from long-haul connections by airlines that have the type in their fleet, for example from the Gulf or from North America. Which aircraft actually comes on a route changes with the schedule and aircraft rotations, though – don’t rely on a fixed 787-10 connection into the DACH region.

Location Chance of a hit Why
Amsterdam Schiphol high Home base of the KLM 787-10 fleet
London Heathrow high British Airways and international long-haul airlines
Frankfurt irregular Foreign airlines with changing equipment
Munich, Zurich irregular Heavily dependent on schedule and rotations

Fleets and assignments change

Which airline flies which route with which Dreamliner can shift with every schedule change. Before your trip, check arrivals and departures for the type code B78X instead of relying on old lists.

How to follow such flights live is explained in the article on flight tracking with ADS-B. What’s behind type codes like B78X, you can read in the guide IATA and ICAO codes explained.

Never miss a 787-10 again

Set up a sighting alert for the type or a specific registration, and Planetrack notifies you when the aircraft arrives at your airport. Planetrack is launching soon – join the waitlist here.

Spotting tips: where to catch the 787-10 best

Amsterdam Schiphol is the most obvious address for spotters from Germany. At the Polderbaan spotter place, you often get long-haul jets from a short distance – provided the Polderbaan is in use at the moment. Schiphol changes its runway use depending on wind and time of day, so it’s worth checking the current runway direction. How to estimate it is explained in the article Understanding runway direction at airports.

At London Heathrow, Myrtle Avenue is the classic for landings with westerly operations: the aircraft come in low over your head, so you can judge the length of the fuselage very well. There you meet many international airlines in addition to British Airways.

In the DACH region, you need patience and a plan. In Frankfurt, the Zeppelinheim viewing platform is a good choice, in Zurich Spectator Terrace B, in Munich the visitors’ hill. First pick out a specific B78X flight in a tracking service and then plan spot and time around it.

Ready for your 787-10 hunt?

Tick off what you’ve already done.

  • I found a specific flight with type code B78X in the tracking service.
  • I know the expected runway direction at the airport.
  • I know where the sun is at my desired time.
  • My vantage point is publicly accessible and allowed.
  • I have a plan B in case the airline swaps the aircraft at short notice.

Whether your vantage point is legally unproblematic is covered in the article Is plane spotting allowed?.

Photo tips specifically for the 787-10

The 787-10 is an elegant subject, but its length makes its own demands on framing and perspective.

Side profile for the length

What sets the -10 apart from the -9 is the fuselage. A clean side profile shows the proportions best and also helps you with identification later.

Plan your focal length

At 68 meters long, the 787-10 quickly overflows the frame at the edge of the runway. Zoom out a bit further and crop later instead of cutting off the nose or tail.

Show off the chevrons

The serrated engine edges are the trademark of the Dreamliner. A three-quarter view from behind or from the side puts them in the spotlight.

Wing flex at takeoff

In the climb, the carbon-fiber wings flex far upward. A shot just after liftoff shows this typical Dreamliner look especially well.

When the light suits your spot, you can calculate in advance; how that works is covered in the guide Planning sun position for your photo spot. The article Lens and focal length for plane spotting discusses suitable focal lengths. And if you’re just starting out, Identifying aircraft types for beginners helps you get started.

Common mix-ups and how to rule them out

It points to the 787-10 if …

  • the engines have serrated trailing edges
  • the wingtips sweep back at an angle without a winglet
  • the fuselage looks conspicuously long relative to the wing
  • the tracking service shows B78X as the type

Take a closer look if …

  • you only see the aircraft head-on or in strong telephoto – lengths are deceptive then
  • the airline flies the 787-9 and 787-10 in parallel, such as KLM or Etihad
  • you only see the fuselage and tail from behind

It’s not a 787-10 if …

  • you count six wheels per main landing gear leg
  • the cockpit windows carry a dark mask
  • the wingtips end in a winglet or sharklet
  • you see four engines – then you’re looking at something like the Boeing 747-8 or the A380

Conclusion

The 787-10 is the Dreamliner for spotters with a trained eye. You recognize the family instantly by the chevrons and winglet-free wings, the long fuselage tells you the variant, and the registration provides the confirmation. In German-speaking countries it is a rare visitor, which makes every sighting something special. If you want to see it for sure, plan a trip to Amsterdam or London.

Bottom line

Serrated engines, wings without winglets, four wheels per landing gear leg and a conspicuously long fuselage: that’s the 787-10. Filter for B78X, plan visiting flights in Frankfurt, Munich or Zurich carefully – or head to Schiphol, where KLM flies the type regularly.

Summary

  • The 787-10 was launched in 2013, flew for the first time in March 2017 and went to launch customer Singapore Airlines in March 2018.
  • It shares wing, cockpit and engine options with the 787-9 but has the longest fuselage and, in return, less range.
  • You separate it from the 787-9, A350-1000 and 777-300ER by fuselage length, landing gear and engine nacelles.
  • In Europe, Amsterdam Schiphol with the KLM fleet is the most reliable address, plus London Heathrow with British Airways.

Frequently asked questions

What is the ICAO type designator of the Boeing 787-10?

The 787-10 operates under B78X. The 787-8 has the code B788, the 787-9 the code B789. With B78X, you can filter for the longest Dreamliner version in tracking services and arrival boards.

How do I tell the 787-9 and 787-10 apart?

Both have the same wing with a 60.1 m wingspan and the same four-wheel main landing gear. But the -10 is around 5.5 m longer, stretched ahead of and behind the wing. As a result, the fuselage looks much longer relative to the wing, and the wing sits visually closer to the middle. Only the registration gives you absolute certainty.

How do I tell the 787-10 from the Airbus A350-1000?

The A350-1000 has a dark cockpit mask, softly upward-curved wingtips, smooth engine trailing edges and six wheels per main landing gear leg. The 787-10 shows serrated chevrons on the engines, wingtips swept back at an angle and four wheels per leg.

Why is the 787-10 built only in South Carolina?

The center fuselage sections of the 787-10 are so large that they can’t be transported economically to the Everett factory near Seattle. That’s why the -10 was a pure Charleston product from the start. Since 2021, Boeing has built all 787s only in North Charleston anyway.

Does Lufthansa fly the 787-10?

No. Lufthansa operates the 787-9, not the longer -10. Swiss and Austrian Airlines don’t have a 787-10 in their fleets either. In the DACH region, you therefore see the type only with foreign airlines.

Who was the launch customer of the 787-10?

Singapore Airlines. The airline took delivery of the first aircraft on March 25, 2018 in North Charleston. That made the Singapore Airlines group the first to operate all three Dreamliner versions, because its subsidiary Scoot already flew 787-8s and 787-9s.

Which engines does the 787-10 have?

As with the whole 787 family, the airline can choose between the GE Aerospace GEnx-1B and the Rolls-Royce Trent 1000. Both have the serrated chevrons on the nacelle; telling them apart works better by the logos on the cowling or by the registration.
