The Boeing 777X is finally getting closer to commercial service, but the aircraft’s long road to certification has created a problem that Boeing may not have expected when the first customer jets rolled off the production line.
Some of those aircraft are now years old.
That has become a major issue for Emirates and Lufthansa, two of the most important customers for the 777-9. Both airlines remain committed to the aircraft itself, but neither wants to simply accept some of the earliest airframes built for them after years of storage and development changes.
For Boeing, that distinction matters. The problem is not that customers have lost faith in the 777X. Instead, airlines are questioning whether early-production aircraft still make commercial sense after sitting idle for years while the programme moved toward its final certified configuration.
Emirates has already made its position clear. The Dubai-based airline plans to reject the first 10 or so 777-9s originally allocated to it because of the amount of work required to bring them up to the latest production standard. Emirates President Tim Clark said the aircraft could be around eight years old by the time they are ready for delivery.
That is an awkward proposition for an airline buying a brand-new flagship aircraft.
Boeing has a nearly 40-jet problem
The early-production issue affects more than just Emirates.
Boeing has a group of roughly 39 early-built 777-9 aircraft that have been stored at Everett while the company worked through certification and engineering changes. The manufacturer is establishing a dedicated process to bring these aircraft into a common configuration, with the earliest examples requiring more modifications than later builds.
Under normal circumstances, building customer aircraft ahead of certification can be a sensible industrial strategy.
Boeing expected the 777-9 to enter service in 2020. Producing aircraft early allowed the company to prepare its production system, build manufacturing experience and position itself for customer deliveries once regulatory approval arrived.
What Boeing could not have anticipated was how dramatically the programme would slip.
Certification delays, engineering changes, manufacturing issues, the pandemic and increased regulatory scrutiny pushed the 777X far beyond its original schedule. Boeing is now targeting first deliveries in 2027. The company reported in July that the 777X had reached important certification milestones and continued to expect first delivery that year.
The result is an unusual situation: aircraft that were supposed to be among the first examples of a new generation of widebody jets have spent years sitting on the ground before carrying a single airline passenger.
Lufthansa joins Emirates in pushing back
Lufthansa has now added another complication for Boeing.
The German airline, which is expected to become the 777-9 launch operator, is in discussions with Boeing over which early-built aircraft it will accept and which it may reject. Lufthansa CEO Carsten Spohr said the airline is also considering whether some aircraft could be modernised if Boeing provides financial support.
That approach is less absolute than Emirates’ decision, but the message is similar.
Lufthansa does not want to take a large number of early-production aircraft simply because they were originally assigned to the airline. If Boeing can bring them up to an acceptable standard and make the economics work, some could potentially enter the fleet. Otherwise, the airline has little incentive to compromise.
The timing makes the situation even more interesting.
The first Lufthansa 777-9 has already flown. Boeing said the aircraft, fitted with Lufthansa’s full passenger cabin, completed its first flight in May 2026 as it moved toward additional testing and eventual certification work. Boeing also said the 777X programme had accumulated more than 4,700 flight-test hours and had more than 620 aircraft ordered across the family.
So the programme is moving forward. But the early-build aircraft remain a separate headache.
The Airbus A350 has gained an important advantage
The 777-9’s biggest problem may not be another Boeing aircraft. It may be the Airbus A350-1000.
The A350-1000 has already been flying passengers since 2018, giving airlines years of operational experience with a modern twin-engine widebody. Qatar Airways was among the first operators, and the aircraft has since established itself on long-haul routes around the world.
That creates an important contrast.
The Boeing 777-9 is designed to be a major step forward in capacity, efficiency and passenger comfort. It is larger than the A350-1000, uses GE Aerospace’s GE9X engines and features a composite wing with folding wingtips that allows Boeing to combine a very large wingspan in flight with compatibility at existing airport gates.
Boeing says the 777X family will deliver significant improvements in fuel consumption and emissions compared with the aircraft it replaces.
But airlines evaluating their fleets do not look at specifications alone.
They also consider delivery timing, reliability, maintenance, residual value and the amount of operational experience behind an aircraft.
That is where the A350-1000 currently has a clear advantage.
The aircraft is already carrying passengers, while Boeing is still completing the certification process for the 777-9. The longer the 777X programme remains in development, the more valuable that operational head start becomes for Airbus.
The 777-9 still has a powerful proposition
None of this means the 777-9 has become an unwanted aircraft.
Quite the opposite.
The type is aimed at one of the most valuable parts of the widebody market: high-capacity long-haul routes where airlines need more seats without returning to four-engine aircraft.
The 777-9 is also expected to become the largest twin-engine passenger aircraft in service, making it particularly attractive to airlines operating from slot-constrained hubs.
Emirates is perhaps the clearest example. The airline has 270 777-9s on order and expects the type to play an important role in its future fleet alongside its existing Boeing 777s and Airbus A380s.
Its rejection of the earliest aircraft therefore should not be interpreted as a rejection of the 777X.
It is a rejection of the economics surrounding aircraft that have aged on the ground before entering commercial service.
Boeing’s next challenge is finding a home for the early jets
That could become one of the most expensive consequences of the 777X’s long development cycle.
Boeing has already acknowledged that early aircraft require different levels of modification, with the oldest examples requiring the greatest amount of change. The company has created a dedicated team and process to handle this work separately from normal 777 production.
The question is what happens after that work is completed.
Some aircraft could eventually be accepted by their original customers. Others could require discounts, financial compensation or other commercial incentives. There may also be opportunities to redirect aircraft to different customers, although that becomes harder when an airframe was originally configured for a particular airline and has spent years in storage.
The possibility of aircraft being written off or permanently removed from the programme cannot be ignored either.
That is the uncomfortable legacy of producing a new aircraft ahead of certification when the certification process takes years longer than planned.
For Boeing, the priority now is clear: get the 777-9 certified, deliver the latest-standard aircraft and prove that the long wait was worthwhile.
But the first customers have already drawn a line in the sand.
They want a new aircraft—not simply an old production airframe that has finally been made ready for service.
That distinction could define one of the final chapters of the Boeing 777X’s long journey to the skies.
