On September 17, Deutsche Lufthansa‘s supervisory board did something that would have seemed improbable a few years ago: it approved 20 Boeing 737 MAX 10s to replace Airbus narrowbodies inside Europe’s largest airline group. The 20 aircraft carry a combined list value of roughly $3.4 billion and were drawn from purchase options already held. They are explicitly earmarked to replace older Airbus A320-family aircraft across the group’s airlines. Boeing metal pushing out Airbus metal, in Airbus’s own backyard.
Lufthansa originally ordered 40 Boeing 737 MAX 8s in 2023 and secured 60 purchase options across the MAX family at the same time. Wednesday’s decision converts the first 20 of those options and selects the larger MAX 10 variant. The headline number to watch is not 20. It is the 40 options still sitting unexercised. If those convert too, Boeing’s total Lufthansa commitment doubles.
Here is the complication. After completing its final planned certification flight test, Boeing is now submitting final deliverables to the FAA, targeting MAX 10 certification in 2026 and commercial deliveries beginning in 2027. Bloomberg reported in July that, barring unexpected issues, FAA certification is likely around October. That window is now. And it is also the exact window in which Boeing’s own engineers could walk off the job.
The Vote That Could Freeze Everything
Boeing this month released the full details of its revised four-year contract offer to more than 16,000 engineers, scientists, and technical workers represented by SPEEA. Voting runs electronically from September 24 through October 1. The current contracts expire October 6. A second rejection means a strike is live from October 7.
Boeing relies on SPEEA-represented personnel, including some who work within the FAA’s Organization Designation Authorization framework, on certification-related work and documentation. A strike would risk slowing regulatory compliance and certification workflows, creating a potential bottleneck for FAA certification activity on new aircraft. The MAX 10 and 777-9 entry-into-service programs are particularly vulnerable to those delays.
The revised offer is better than August’s rejected package. Boeing says the offer now includes 34% in total wage funds over the life of the contract, with 26% fully guaranteed. A 10% wage increase would take effect October 2 if ratified, with another 4% guaranteed increase in March 2027. Both bargaining teams are recommending a yes vote. But the membership rejected the first offer by 64.25% and 71.87% margins in August, with strike authorization passing at 87.82% among professionals and 89.71% among technical workers, with turnout above 92%. Rank-and-file sentiment is not automatically soft.
The Options Trade
This is where the asymmetry lives for BA. The stock has recovered from its 2024 lows and the Lufthansa order confirms that demand for Boeing narrowbodies is real and growing. But the next three weeks carry binary risk that the options market is pricing in real time.
A ratified contract removes the single biggest near-term threat to MAX 10 certification timing and keeps Boeing’s recovery momentum intact. A failed vote sends the stock lower and puts Lufthansa’s early-2030s delivery schedule in question, not because the order goes away, but because the certification timeline the order depends on gets pushed further out.
In the interest of protecting 737 MAX production and ensuring certification progress continues on the MAX 10 and 777X programs, Boeing is highly motivated to avoid a work stoppage. A labor disruption is one of the last things the company needs right now. That motivation is exactly why a defined-risk long call position in BA, positioned to benefit if the contract ratifies and certification news follows before October expiration, offers a clearly bounded entry point.
The thesis invalidates on a no vote, full stop. Size accordingly, and watch the SPEEA results on October 1.
