Boeing Engineers Threaten Strike Over 777X Certification

Boeing engineers represented by the Society of Professional Engineering Employees in Aerospace (SPEEA) are threatening to go on strike, which could halt certification of the company's 777X aircraft.

The 17,000 engineers have been working without a contract since October 6, 2026, and their current proposal has been rejected. The union authorized a strike by an 88% vote after rejecting the offer, and Boeing countered with a 10% wage hike on September 11, which is awaiting ratification voting.

According to CEO Kelly Ortberg, if the engineers go on strike, certification of the 777X would be completely halted. This could delay deliveries past 2027 and hurt investor confidence.

The 777X has been plagued by delays and budget overruns, with airlines such as Emirates and Lufthansa awaiting delivery. A strike would also give Airbus an opportunity to gain ground in the market with its A350-1000 alternatives.

Boeing's previous machinist strike in 2024 cost the company $24 billion, and investors are watching closely for any repeat disruption to CEO Ortberg's turnaround plan.
