What is the Reason for the Diversion?
During the transpacific flight, about five hours in, the flight crew received an alert indicating a malfunction in the engine’s anti-ice system—a critical system that prevents dangerous ice buildup during high-altitude flights in cold areas such as the Bering Sea.
This issue, while not immediately life-threatening, could worsen in colder conditions. As a result, the flight crew made a cautious decision to divert to a safe airport before entering high-risk airspace.
Why Was LAX Chosen?
Many questioned why the flight did not land at a nearby airport. However, LAX was chosen for valid operational and safety reasons:
Key Reasons for Choosing LAX
| Maintenance Capability |
LAX has Delta-certified A350 and Rolls-Royce maintenance facilities. |
| Passenger Support Services |
Hotels, rebooking, meals, and multiple international flights are available. |
| Better Weather Conditions |
Southern California offers favorable landing conditions compared to northern airports. |
| Runway & Emergency Support |
Long runways and full emergency crew availability. |
| AI & Diagnostic Support |
LAX can support deeper diagnostics using predictive tools. |
The aircraft landed safely on Runway 06R at LAX in the early hours of May 28, 2025.
