Airbus A340-300

Four slim engines, a third landing gear leg under the fuselage and the fuselage of an A330: the A340-300 is Airbus’s classic long-haul four-engine jet – and it is vanishing from Europe’s fleets. Here is how to recognize it while you still can.

Key takeaways

  • The A340-300 is the long-haul four-engine jet of the first A340 generation: fuselage of an A330-300, but four CFM56 engines and an additional center landing gear.
  • Fastest way to identify it: four slim engines plus winglets and a fuselage without a hump.
  • You tell it from the A340-600 by length, engine size and the center gear with two instead of four wheels.
  • The farewell is under way in the DACH region (Germany, Austria, Switzerland): Lufthansa, Swiss and Edelweiss are gradually retiring their A340-300s, as of October 2026.
  • In flight schedules and tracking apps the type appears as A343.

Identifying features

Is this really the aircraft type in front of you?

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

  • Four engines under the wings, all comparatively slim and the same size
  • A third landing gear leg with two wheels in the center under the fuselage, between the two main landing gears
  • Fuselage, cockpit and tail practically identical to the A330-300 – classic Airbus nose without a dark mask
  • Slanted-up, classic winglets at the wingtips
  • Overall length just under 64 m – clearly shorter and more compact than the stretched A340-600
  • No hump on the fuselage and only one passenger deck – that immediately separates it from the Boeing 747 and A380

Updated: October 2026 – A long-haul jet taxis to the runway, and under the wings you count not two but four engines – slim, all the same size, with no hump on the fuselage. Then you very likely have an Airbus A340-300 in front of you. For decades the four-engine jet was a backbone of European long-haul, and by now it is being retired at almost all operators. Here you learn how to reliably tell the A340-300 from the A330-300 and the A340-600, and where in the German-speaking world you can still get it in front of your lens.

Check off the A343 in your hangar

With Planetrack you log every A340 sighting with registration, airline and spot, and check off the type in your hangar before it disappears completely. Planetrack is launching soon – join the waitlist and get early access.

What is the Airbus A340-300?

The A340-300 is the main version of the first A340 generation – a widebody aircraft with two aisles in the cabin and four engines. Airbus developed the A340 in parallel with the twin-engine A330. The two types share large parts of fuselage, wing, tail and cockpit; the difference lies mainly in the propulsion. While the A330 targeted medium and long-haul routes with two large engines, the A340 was intended for very long routes, including over oceans and remote regions.

The reason for the four engines lay in the rules of the time: twinjets were only allowed to fly routes far from alternate airports with restrictions (ETOPS). A four-engine jet was not affected. The -300 is powered by four CFM56-5C, an engine family you also know in a smaller version from the A320 family. There was no engine alternative for the -300.

The A340’s first flight took place on October 25, 1991, and the type entered service in March 1993. The launch customers were Lufthansa and Air France, and the first -300 went to Air France. The improved A340-300E (Enhanced) followed later, with a higher takeoff weight and about 13,500 kilometers of range. In total, Airbus delivered 218 A340-300s – more than of any other A340 version. In November 2011, the manufacturer announced the end of A340 production because twin-engine widebody jets like the A330 and the Boeing 777 had become more economical. You can find more about the history of the manufacturer on the page about Airbus.

The three features that are enough to identify it

The A340-300 is one of those aircraft you can narrow down from a long way off. These three observations are enough in almost all cases.

Count the engines

Four engines under the wings on a fuselage without a hump and with only one passenger deck: that already puts you in the A340 family. Compared with modern widebody engines, the four CFM56s look strikingly slim.

Look under the fuselage

Between the two main landing gears sits a third, smaller landing gear leg with two wheels. On landing and taxiing it is easy to see and sets the -300 apart from the -600 with its four-wheel center gear.

Check the proportions

At just under 64 meters in length, the -300 looks compact and balanced. The A340-600 is about twelve meters longer and looks almost overstretched in proportion to the wing.

In the end, the registration confirms the type. How to read registrations and interpret the country code is explained in the article Understanding aircraft registrations.

Practical tip for the first look

On approach from the front you see all four engine inlets side by side – that alone is enough. You spot the center gear best from the side, when the aircraft passes you just before touchdown or while taxiing.

A340-300 or A330-300?

This mix-up is the most common, because the two types are almost twins from nose to tail. The A330-300 is nearly as long and also has classic winglets. What counts is what hangs under the wings and under the fuselage.

Feature A340-300 A330-300
ICAO type designator A343 A333
Engines 4 × CFM56-5C 2 × GE CF6, PW4000 or Trent 700
Engine size slim much larger diameter
Landing gear legs 3 (center gear with 2 wheels) 2
Length 63.69 m almost identical
Wingspan 60.30 m 60.30 m

If you count the engines on an A330, you are done quickly. The difficulty comes more from behind or in backlight, when you only see the outline. Then a look at the underside of the wing helps: two engines per side means A340. How to systematically check such family differences is shown in the guide Recognizing aircraft types for beginners.

A340-300 or A340-600?

Within the family, the A340-600 is the most important comparison, because Lufthansa operated both versions in parallel for a long time. The -600 belongs to the second A340 generation, together with the ultra-long-range A340-500.

Typical A340-300

  • Fuselage just under 64 m, compact proportions
  • Slim CFM56 engines
  • Center gear with two wheels
  • Type code A343

Typical A340-600

  • Fuselage a good 75 m, very stretched
  • Thicker Rolls-Royce Trent 500 engines
  • Center gear with four wheels
  • Type code A346

There was also the shorter A340-200 (type code A342) from the first generation. It is practically no longer found in Europe today and was recognizable mainly by its shorter length with fewer windows ahead of and behind the wing.

Four-engine finder: A340, 747 or A380?

If you see four engines, only a few types are still possible in scheduled service. The finder narrows them down through three observations.

Quick ID: four-engine long-haul jet

Three questions, one assessment. The registration remains the final authority.

Likely

Airbus A340

One deck, no hump and an additional landing gear leg under the fuselage: that is the A340 family. Now length and engine size decide between -300 and -600.

Likely

Boeing 747

The hump with the upper deck is unmistakable. You can find more about the variants at the 747-400 and the 747-8.

Likely

Airbus A380

Two full-length passenger decks exist only on the A380. Next to it, an A340 looks almost delicate.

How to tell Airbus and Boeing families apart in general, for example by cockpit windows and nose shape, is covered in the article Telling Airbus and Boeing apart.

Where you can still find the A340-300

The A340-300 is a type you should photograph now. All three big operators in the German-speaking world are replacing it with more modern twinjets, and the situation changes from schedule to schedule. The following overview describes the status as of October 2026.

Lufthansa is, according to available data, still the largest A340 operator and uses the -300 mainly from Frankfurt Airport, for example on North America routes. Reports give 2027 or 2028 for the retirement of the -300; no clear official end date has been published. According to reports, Lufthansa is already saying goodbye to the larger A340-600 in fall 2026.

Swiss still flies four A340-300s from Zurich Airport, according to industry data. As the A350-900 arrives, the airline is gradually phasing out the four-engine jet; according to reports, the last aircraft leave in early 2028. In September 2026, Swiss and the Swiss Museum of Transport announced that they would display the last aircraft (HB-JMH) in Lucerne – provided that the costly transport is funded by the end of 2026.

Edelweiss, the leisure airline of the Swiss family, retired the first of its A340-300s in October 2025 and is replacing the fleet with A350-900s. How many Edelweiss A340s are still flying in fall 2026 is something you should check on the day.

Swiss, Edelweiss and Lufthansa all belong to the Lufthansa Group; Lufthansa and Swiss are also members of the Star Alliance. In addition, there are other, mostly smaller operators worldwide that occasionally also fly to Europe.

Place Chance of success Why
Frankfurt medium Lufthansa deployments, retirement expected by 2027/28
Zurich medium, declining Swiss with a few remaining aircraft, Edelweiss phasing out
Munich low Hardly any regular -300 deployments, at most individual flights
Smaller airports very low At most charter, wet lease or ferry flights

Retirements are under way

With the A340-300, deployments can be dropped at short notice or swapped for other types. Don’t rely on older route lists; before every trip, check arrivals and departures for the type code A343.

How to follow flights live and what ADS-B data reveals is explained in the guide to Flight tracking with ADS-B. Further tips for phasing-out types are in the article Spotting rare aircraft.

Don’t miss the last four-engine jet

Put the type A343 or individual registrations on your wish list and get notified by a sighting alert when they approach. Planetrack is launching soon – join the waitlist.

Spotting in Frankfurt and Zurich

In Frankfurt, the Zeppelinheim viewing platform is a popular vantage point for watching long-haul jets. Which side of the airport is active at a given moment depends on the runway direction in use – it determines from which direction aircraft land and where they take off to. How to estimate it in advance is covered in the article Understanding the runway direction in use at an airport.

In Zurich, Spectator Terrace B is a good choice for apron and taxiing traffic, and the Butzenbüel for movements on the runways. With the Swiss long-haul flights in particular, it pays to look up the departure waves in the schedule, because the remaining A340s now fly only on selected routes.

Ready for your A340 session?

Check off what you have already done.

  • I have found a current flight with the type code A343.
  • I checked shortly before the trip that the deployment was not swapped.
  • I know the expected runway direction in use.
  • I know where the sun is at the desired time.
  • My vantage point is publicly accessible and permitted.

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

Photo tips especially for the A340-300

The A340 is a subject many spotters are collecting right now – as a memory of the era of four-engine long-haul. With a few tricks you get the best out of it.

Show all four engines

The trademark of the A340 is its four engines. A slightly elevated three-quarter front view brings both wings with their engines into the frame.

Capture the center gear

In side profile on landing, the third landing gear leg is clearly visible – a detail that sets an A340 photo apart from an A330 photo.

Light at your back

Light fuselage liveries and dark engine inlets create strong contrasts. Low light from behind preserves detail in both.

Keep farewell flights in mind

When airlines retire a type, there are often last rotations or special flights. Watch for operator announcements and plan such days early.

When the light works at your spot can be calculated in advance; how that works is explained in the guide Planning sun position for your photo spot. Suitable focal lengths are in the article Lens and focal length for plane spotting, and if you are just starting out, begin with Plane spotting for beginners.

Common mix-ups and how to rule them out

It points to the A340-300 if …

  • you count four slim engines
  • a third landing gear leg with two wheels sits under the fuselage
  • the fuselage looks compact, about like on an A330
  • the tracking service shows A343 as the type

Take a closer look if …

  • you only see the aircraft from behind or in backlight
  • the fuselage looks strikingly long – then it could be an A340-600
  • you cannot count the engines reliably because of the perspective

It is not an A340-300 if …

  • only two engines hang under the wings – then it is more likely an A330-300 or A330-200
  • the center gear has four wheels
  • the fuselage shows a hump or a second deck
  • the cockpit windows have a dark surround – that is the A350’s mask

Conclusion

The A340-300 is a piece of aviation history that is disappearing from everyday life. Four engines narrow down the family, the two-wheel center gear and the compact length give the variant, the registration the confirmation. If you still want to experience it in scheduled service, your best chances are in Frankfurt and Zurich – but not forever.

Quick verdict

Four slim engines, winglets, a center gear with two wheels and just under 64 meters in length: that is the A340-300. Filter for A343 and plan your trips soon, because Lufthansa, Swiss and Edelweiss are expected to retire the four-engine jet by 2028.

Summary

  • The A340-300 first flew in October 1991 and entered service in March 1993 – the launch customers of the family were Air France and Lufthansa; 218 aircraft of this version were built.
  • It largely shares fuselage, wings and cockpit with the A330, but has four engines and a third landing gear leg.
  • Lufthansa, Swiss and Edelweiss still operate A340-300s in October 2026, and all three are replacing them with more modern twinjets.
  • If you still want to photograph the type, filter for A343 and plan for the coming months – Frankfurt and Zurich are the best addresses.

Frequently asked questions

What is the ICAO type designator of the A340-300?

The A340-300 is listed as A343. The shorter A340-200 has the code A342, the A340-500 A345 and the long A340-600 A346. With A343 you can find the aircraft specifically on the arrival and departure boards of tracking services.

How do I tell the A340-300 from the A330-300?

Both have almost the same fuselage and nearly the same length. The difference is under the wings: the A340-300 has four engines and a third landing gear leg in the center under the fuselage, the A330-300 only two much larger engines and two main landing gear legs.

How do I tell the A340-300 from the A340-600?

At a good 75 meters, the A340-600 is about twelve meters longer, has visibly thicker Rolls-Royce Trent 500 engines and a center gear with four wheels. The -300 has slim CFM56 engines and a center gear with only two wheels.

Why does the A340 have four engines?

When Airbus developed the A340, twin-engine jets were only allowed to fly routes over oceans with restrictions (ETOPS rules). With four engines these restrictions did not apply. Later, twinjets like the A330 and Boeing 777 were certified ever more freely and burned less fuel – that put the four-engine jet under economic pressure.

Is the A340-300 still being built?

No. Airbus announced the end of A340 production in November 2011. A total of 218 -300s were delivered.

Where can I still see an A340-300 in Germany?

Most likely in Frankfurt with Lufthansa. According to reports, Lufthansa intends to retire the type around 2027 or 2028; an official end date is not clear. In addition, foreign operators show up occasionally. Check the current schedule for A343 before every trip.

What will happen to the last Swiss A340?

In September 2026, Swiss and the Swiss Museum of Transport announced that they would display the airline’s last A340-300 (HB-JMH) in Lucerne after its retirement in early 2028. The transport still has to be funded, however, so the project is not definitively secured.

Collect the Airbus A340-300, don’t just see it

Post a photo with registration, type, airport and spot, check off the type in your hangar and get an alert when a registration you are looking for lands. Planetrack is launching soon – join the waitlist and get early access.
