Every now and again, an aircraft stealthily takes to the air, and aviation buffs know about it. Lufthansa will fly its last Airbus A340-600 passengers' flight on Sunday, October 18, 2026, marking the end of a more than 20-year era.

What is going on, why the plane hasn't left and why are so many people not getting to see it.

The Final Flight

The last passenger flight will be LH419 from Washington Dulles (IAD) to Frankfurt (FRA), landing on the morning of October 19. From then on, the A340-600s will no longer be in passenger service.

The A340-600 is the longest stretched of the A340 family. Previously the longest aircraft in the world, until the Boeing 747-8 was introduced into service. It is a bit longer than the Airbus A380 and the Boeing 747-400, which seems like a stretch given its width.

It's appropriate that the trip from Washington to Frankfurt is transatlantic, as the journey is meant as a farewell. These planes were in service for years, flying between Germany and North America, and were the subject of many fond memories among those who travelled on them. The last landing in Frankfurt will be an event to remember for both plane spotting and frequent flyers.

A 23-Year Run

Lufthansa acquired 24 A340-600s from 2003 to 2008. Just four planes remain flying these days, far from the days when the type was a regular sight all over the network.

The ships would have left almost to the very last minute. Lufthansa was actually planning to retire the planes at the beginning of the pandemic, and temporarily grounded them. After which it returned them, partly due to the increased demand being met faster than anticipated, and partly due to delivery delays of other aircraft.

The grounding bought the aircraft a few more years of life, something many fans did not anticipate when it was grounded. The comeback is rare in a business where older planes may be sold out before they take off when on the ground.

Lufthansa Kept Them So Long, Why?

The primary reason for the A340-600 remaining in service was because of the delays. Lufthansa kept the plane around due to delays with Boeing 777X deliveries, along with delays of Airbus A350s and Boeing 787s, largely due to problems with Allegris cabins. The newer aircraft were late to arrive and the older four-engine jets filled the gap.

When new planes appear on the scene, years later, airlines have limited options when it comes to their fleet planning. Maintaining an older, more thirsty aircraft in the air is sometimes the only option to maintain schedule, even if it requires more of a cost to operate.

The replacement of the A320 with the A350-1000s has made retirement of this type sensible now. The A340-600 has a poor reputation for efficiency and Lufthansa is known to have put many more years into the aircraft than was initially anticipated.

What Is Still Flying

Lufthansa's four-engine flying is far from over. The airline continues to fly almost a dozen Airbus A340-300s. That is the smaller version of the aircraft and has much weaker engines. Those planes should be phased out sometime in 2027.

For those who are still hoping for one final flight on a Lufthansa quad-jet, there is still time. Simply won't contain the longer and more dramatic A340-600. If you're considering flying on one of the remaining A340s, it is best to book early before you miss the opportunity to do so as schedules can change.

The reasons why aviation fans will miss it are listed below:

• Anyone would say that this retirement is bad in any way for passengers. Nevertheless, this A340-600 has some nice features.
• The plane is long and thin, and has four very large engines.
• Economy cabin: some passengers were delighted, particularly its 2-4-2 configuration.
• Cargo hold lavatories: the A340-600's cargo hold is equipped with lavatories, which is pretty cool.

A Personal Soft Spot

This is a sad retirement for the original writer for a couple reasons. The first one is, most of us probably will never fly an Airbus A340-600 for the second time in our lives so, it is definitely the end of an era.

The second one is personal. The author is rather skeptical of Lufthansa these days, but still has a fondness for the airline. They were used to flying Lufthansa regularly to Germany and the love of flying Lufthansa first class was what attracted them to miles and points in the first place. Once Lufthansa's first class product, the A340 is a fine reminder of the airline's glory days 20 years ago. Good times.

Some love even Frankfurt Airport. The airport has its troubles, but a childish delight in walking through the Z Gates and seeing 747-400s, A340-300s, A340-600s and 747-8s. It's a special place for plane fans.

It will be a sad day indeed if Lufthansa no longer has any 4-engine planes in service.

This is where they haven't yet been eradicated

It will be the last time that most travelers will ride on an A340-600 after this week. At this time, the only airlines for which the type are in regular service are Conviasa (Venezuela) and Mahan Air (Iran). If you are interested in becoming a pilot, it is definitely a rare opportunity.

That is why this is a definite conclusion to be the end of an era. The plane was once among the most impressive in the sky, but is now nearly extinct in commercial use. It will soon be just a memory or photograph for those who once saw four enormous engines on a long, thin fuselage.

The Bottom Line

On the other hand, Lufthansa is in the process of retiring its Airbus A340-600 fleet this week, which will be the end of a 23-year run with the jet at the airline. They will continue to fly the A340-300s until 2027, but let's face it, the A340-600 is a much more handsome plane than the A340-300.

It seems logical that Lufthansa is getting rid of it, particularly in the light of the new A350-1000s being added and its inefficiency. We even had a few additional years from it than we had hoped for! However, this is with the end of an era as only A340-600s are available with carriers such as Conviasa or Mahan Air.
