Boeing 787 Dreamliner: planes are built, but they can't leave the lot
Boeing delivered just 15 787 Dreamliners in the first quarter of 2026 — up from 13 in Q1 2025, but still a fraction of what airlines are waiting for. The aircraft are built. Many are sitting complete at Boeing's facilities. The problem, CEO Kelly Ortberg confirmed, is that engines and premium cabin seats cannot clear their respective certification and supply hurdles fast enough to hand the planes over to customers.
The bottleneck has shifted from Boeing's own factory floors to its suppliers, and that shift turns out to be just as costly.
The dual choke point
The 787 program offers airlines a choice between GE Aerospace and Rolls-Royce engines. Right now, both suppliers are under pressure. Post-pandemic travel demand pushed engine makers to their limits, creating delivery backlogs that leave finished airframes engineless on the ramp. Without a certified powerplant installed, a completed fuselage is just an expensive carbon-fiber shell.
The seat problem sounds almost absurd by comparison — but it's equally real. Modern business- and first-class seats are complex engineering products: motorized flat-beds, embedded electronics, structural safety systems. Every new seat design requires FAA certification before an aircraft can enter service. Carriers including Lufthansa and Air India have aircraft parked at Boeing awaiting exactly that approval, per Aviation A2Z. Lufthansa CEO Oliver Spohr confirmed at least 15 of the airline's 787s are waiting on seat sign-off — blocking roughly 85% of its new Allegris business cabin from entering service.
What Boeing says
Ortberg has been candid about the situation. In comments reported by Air Data News, he described a "pig through the python" dynamic: a bulge of near-complete aircraft that need a handful of final certified components before they can move. Boeing's stated target for 2026 remains 90–100 deliveries, with production currently at 8 per month and a goal of 10 per month by year-end.
The order book exceeds 1,100 aircraft — enough work for years — but the reputational cost of parking finished jets mounts with each passing quarter. On the engine side, Rolls-Royce secured its first new 787 order in 34 months in March 2026, a tentative sign that its Trent 1000 durability problems are receding. GE Aerospace still holds around 78% of 787 engine orders, according to analyst data cited by FlightGlobal.
The bigger picture
For US carriers like United and American — both with 787-10 upgrades in the pipeline — multi-month delays translate directly into grounded routes and deferred revenue. Boeing is working with the FAA on accelerated seat certification timelines, but no public schedule has been released. Until suppliers catch up, new Dreamliners will keep accumulating on tarmacs, a reminder of how a single uncertified seat can stall a billion-dollar aircraft program.
