The Jet Shortage Switched Sides
Boeing just out-delivered Airbus for the first time since the MAX crisis, while Airbus's 870-jet guidance now requires a five-month sprint it has never achieved — with its engine supplier in arbitration. Who carries the risk, and who gets paid either way.
Airbus closed out last week with a delivery report that read as routine and was anything but. Sixty-seven aircraft handed over in July — flat against the same month last year — bringing the 2026 total to 418 jets. Set against the company's reaffirmed full-year guidance of roughly 870 deliveries, the arithmetic is stark: 452 aircraft in five months, an average of 90 per month, from a company that has averaged around 60 all year.
For six years, this was not the conversation anyone expected to be having about Airbus. Since the 737 MAX groundings in 2019, through the door-plug blowout and the FAA's production cap, the supply problem in commercial aerospace had one name on it: Boeing. Airlines planned around Boeing's failures. Lessors priced around them. Investors built the entire duopoly trade around one assumption — Airbus executes, Boeing apologizes.
That frame is now out of date, and the delivery data says so. In the first quarter of 2026, Boeing handed over 143 commercial aircraft to Airbus's 114 — its first quarterly delivery win over its European rival since the MAX crisis began. Boeing's FAA production cap is off, its backlog sits at a record $695 billion, and its free cash flow has turned positive. At July's Farnborough Airshow, Boeing out-ordered Airbus in widebodies 52 to 30.
Meanwhile, the bottleneck moved to Toulouse — or more precisely, to the engines that aren't arriving there.
The Engine Problem Airbus Can't Build Around
Roughly 40% of the A320neo family flies on Pratt & Whitney's geared turbofan; the rest on CFM International's LEAP. When Pratt's powdered-metal defect forced a mass inspection campaign, the damage compounded through the fleet: by late 2025, more than 800 PW1000G-powered jets were grounded or stored worldwide, a record for the program.
The production side is where it hits Airbus's guidance. CEO Guillaume Faury has said plainly that Pratt & Whitney's "failure to commit" to the engine volumes Airbus ordered is what forced the company to guide 2026 deliveries to around 870 — below the 900-plus the Street had penciled in — and to push its target of building 70–75 A320-family jets per month out to the end of 2027, a full year's slip. Commercial chief Christian Scherer described engines arriving "very, very late."
Then Airbus did something the aerospace duopoly has rarely seen in public: it moved to pursue financial damages from its own engine supplier, with arbitration the likely venue if no settlement is reached. Airbus is, in effect, litigating against the company it needs most to hit the number it just reaffirmed.

Two Stories That Can't Both Be Right About December
Here is what makes this moment genuinely interesting for investors: both sides just reported quarters that support their own version of events.
Airbus delivered a record 237 aircraft in the second quarter — up nearly 40% from a weak Q1 — and reaffirmed the 870 target with what management called increasing confidence. RTX, Pratt & Whitney's parent, beat on second-quarter earnings and raised its full-year guidance. Grounded-aircraft counts for the PW1100 fleet fell for another consecutive quarter and are down 25% year to date. Engine overhaul output is up more than 40%, turnaround times are down 23%, and the upgraded GTF Advantage — designed to double time-on-wing — is certified and now shipping to Airbus.
Both of those quarters happened. Both narratives are, as of today, true. But they converge on a single question that gets answered between now and New Year's Eve: either Airbus delivers 452 jets in five months — a sprint it has never sustained at this scale — or the guidance breaks, and with it the market's assumption about which half of the duopoly carries execution risk.
Who is actually carrying that risk — and who gets paid either way — is where this gets actionable.
The rest of this briefing is for paid members: the December delivery math run scenario by scenario, the RTX asymmetry — why the arbitration overhang is smaller than the aftermarket it threatens, the engine franchise that wins in every branch of the dispute, the lessor angle, and the catalyst calendar through the January scoreboard print.
