Boeing says 777X certification and deliveries now slip to 2027, angering key customers

Boeing CEO Kelly Ortberg announced the certification and entry-into-service of the flagship 777X has slipped to 2027, representing another delay to the programme. The move has angered key customers already frustrated by repeated schedule slippages and pushed back expected deliveries.

Briefing

What Hype is tracking

The schedule move pushes certification and EIS into 2027, further deferring customer deliveries and contractual timelines; it follows reporting that the 777-9 certification programme was running behind schedule.
Certification work has been protracted and operationally intensive: Boeing's recent 63-day brake campaign required 117 wheel/tire changes and encountered severe weather, illustrating how testing demands have extended the timeline.
The announcement reverses earlier signals that the 777X was nearing regulatory approval and entry into service, amplifying commercial and scheduling pressure across airline fleet plans and OEM delivery forecasts (see prior reporting that the 777X was approaching certification milestones).
