Especially the iconic Boeing 747- “Queen of the Skies” holds a special place in the hearts of aviation enthusiasts and travelers alike, evoking a sense of nostalgia and admiration for its iconic design and historical significance.
Therefore, repurposing retired Boeing 747-400 aircraft for long-haul services allows airlines to capitalize on the brand recognition and prestige associated with enhancing their market appeal and competitive positioning in the industry.
While newer aircraft models feature slightly improved fuel efficiency and reduced emissions, the last series of B747’s are very competitive still today in their fuel economy and comparable to modern day aircraft ‑when operated at high load factors‑. The ecological advantage is obvious:
Not wasting resources for building new aircraft when perfectly good used aircraft are available!

Therefore, especially today employing used Boeing 747-400 aircraft can still align with sustainability goals through strategic fleet management and operational optimization. How this can be done is nicely showcased by Lufthansa, which is still very successfully in operating these aircraft as one of the last carriers even to date!
It is also important to note that the Boeing 747-400 can have a better fuel consumption per passenger and mile -compared to much newer aircraft, -in effect up to 6% less per hour -when operating at high load factors.
Lastly, considering the huge amount of available cargo (42t) she still has the potential to be a game changer on our long-haul routes.
Last but not least, the Boeing 747-400 is currently still the fastest passenger aircraft in the skies with a cruise speed of up to 500 knots, effectively taking 45 minutes off the clock on long-haul flight to Los Angeles.
