Airbus vs Boeing Backlog in 2026: What the Numbers Actually Show
At 31 March 2026 Airbus reported 9,037 aircraft in backlog and Boeing more than 6,100. The totals show constrained supply, but not a universal 12-year wait.

Airbus and Boeing entered 2026 with order books far larger than one year's output. At the most recent quarter-end for which both manufacturers published directly comparable statements, Airbus reported 9,037 commercial aircraft in backlog and Boeing reported more than 6,100.
That puts the disclosed combined total above 15,137 aircraft at 31 March 2026. It is a lower-bound calculation because Boeing rounded its unit figure. It is not the former 16,683-aircraft claim on this page, and it does not establish a universal 12-year delivery wait.
The corrected numbers still tell a consequential story: airlines have reserved an extraordinary amount of future production, while the two manufacturers continue working through supply, quality, certification and industrial constraints. But the useful comparison depends on matching dates and understanding what a backlog can — and cannot — say.
The matched Q1 2026 snapshot
| Manufacturer | Net orders in Q1 | Deliveries in Q1 | Backlog at 31 March 2026 |
|---|---|---|---|
| Airbus | 398 | 114 | 9,037 aircraft |
| Boeing | 140 | 143 | More than 6,100 aircraft |
Airbus published those figures in its first-quarter 2026 results. Boeing published its figures in its first-quarter 2026 results.
Together, the manufacturers recorded 538 net orders and 257 deliveries during the quarter. That does not mean the combined backlog simply increased by 281 aircraft: order books also move through cancellations, contractual adjustments and accounting changes, and each company reports under its own definitions. It does show why delivery growth alone may not shrink the queue when new net demand remains high.
Airbus had the larger disclosed unit backlog
Airbus ended 2025 with 8,754 commercial aircraft in backlog after 793 deliveries and 889 net orders, according to its 2025 delivery release. By the end of March, the reported backlog had grown to 9,037.
The same Q1 release said Airbus delivered 114 aircraft and retained its 2026 guidance at roughly 870 commercial deliveries. It also identified a shortage of Pratt & Whitney engines as part of the operating environment. That is important context: an airframer's output depends on engines, structures, interiors, systems, labour and regulatory conformity arriving together, not merely on available final-assembly space.
Airbus's live orders and deliveries table provides later monthly data. That table is useful for following Airbus, but it should not be combined with an unmatched Boeing date and presented as a precise industry total.
Boeing's backlog was rounded, but still at a record value
Boeing said its Commercial Airplanes backlog at 31 March included more than 6,100 aircraft, valued at a record $576 billion. It reported 143 deliveries and 140 net orders for the quarter.
The manufacturer also reported specific production positions: the 737 program was producing at 42 aircraft per month and the 787 program at eight per month. Those are program rates, not total-company delivery forecasts, and they do not translate directly into customer wait times. Stored inventory, rework, certification status, model mix and delivery sequencing all intervene between production rate and handover.
Boeing's Q1 statement also anticipated 737-7, 737-10 and 777-9 certification progress, with first deliveries for those programs expected later than the article's former wording implied. Aircraft that have not completed certification cannot be treated like mature models already moving through a stable delivery system.
Why “backlog divided by deliveries” is not a delivery forecast
Dividing a manufacturer's total backlog by one year's deliveries produces a rough workload ratio. It does not tell an airline when a particular aircraft will arrive.
Five differences break the shortcut:
- Model mix. An A320-family slot is not interchangeable with an A350 slot; a 737 slot is not a 787 slot.
- Production ramps. Future output can differ from the most recent year's deliveries, in either direction.
- Customer sequencing. Airlines have negotiated positions, deferrals and fleet plans that shape the order in which aircraft move.
- Certification and configuration. A not-yet-certified variant or a highly customised cabin follows a different path from a mature, standardised aircraft.
- Backlog quality. Cancellations, conversions, contractual protections and accounting rules can change what remains in the published order book.
That is why “12 years of backlog” is too blunt as a headline conclusion. Some delivery positions may extend well into the 2030s, while other customers receive aircraft sooner under existing agreements. The queue is many model-specific production streams, not one line.
What the backlog does show
The backlog is still strategically important.
For airlines, it means fleet planning must start early. A carrier that waits for today's aircraft to reach retirement age before securing replacement capacity may find that desirable model-year slots are already committed. It also raises the value of lessor relationships, used aircraft, life-extension work and flexible fleet plans.
For suppliers and maintenance organisations, a long new-aircraft queue can support demand at both ends of the fleet. Manufacturers need sustained component output for new builds, while operators may keep existing aircraft flying longer than originally planned. That can extend demand for engines, components, heavy checks and reliability work without making every MRO segment move at the same rate.
For manufacturers, the commercial question is no longer simply whether demand exists. It is how to turn commitments into conforming aircraft without sacrificing safety or quality. Airbus's engine constraint and Boeing's program-by-program production and certification disclosures illustrate why the limiting factor can move across the system.
How to compare the order books responsibly
When a new “record backlog” figure appears, apply four checks:
- Date: Are both manufacturers measured at the same month or quarter end?
- Units: Is the source reporting gross orders, net orders, backlog units or dollar value?
- Precision: Is a number exact, rounded or described only as “more than” a threshold?
- Definition: Are cancellations and accounting adjustments treated the same way?
For the end of Q1 2026, the defensible comparison is 9,037 Airbus aircraft versus more than 6,100 Boeing aircraft. It shows Airbus with the larger disclosed unit backlog and both manufacturers with years of committed production. It does not justify an exact combined figure beyond the evidence, and it does not convert into one delivery wait for every airline.
