Boeing reported a slowdown in jet deliveries in March, with 46 planes handed over to customers compared to 51 the prior month. The company said the decline was due to repairing damaged wiring in about 25 of its 737 MAX aircraft, a process that delayed some deliveries. Boeing's deliveries trailed European rival Airbus, which delivered 60 jets in March.

Why it matters

Jet deliveries are a key metric for planemakers, as they receive most of the payment for an aircraft when it is handed over to a customer. The 737 MAX is Boeing's best-selling model, so any production issues can significantly impact the company's financial performance.

The details

Boeing said it delivered 46 jets in March, down from 51 the prior month, as the company repaired damaged wiring in about 25 of its 737 MAX planes. The company did not specify how many deliveries were delayed by the rework, but in March, Boeing's CFO said it was expected to push 10 737 deliveries into the second quarter without affecting the full-year delivery target.

  • Boeing delivered 143 jets in the first three months of the year, ahead of Airbus' 114 deliveries.
  • Boeing had delivered 41 jets in March 2025.

The takeaway

This delivery slowdown highlights the ongoing production challenges Boeing faces with its 737 MAX model, which remains crucial to the company's financial performance. While the impact on full-year deliveries is expected to be minimal, the wiring issue is a reminder of the operational complexities Boeing must navigate to maintain steady production and meet customer demand.
