United Airlines has begun restoring its flight schedule after a system-wide ground stop temporarily brought its operations to a halt on Wednesday evening due to what the company described as a “technology disruption.”
In an update shared after the issue was resolved, United said it was actively assisting affected travelers and working to stabilize its network. The airline acknowledged that while some delays would persist, crews were making progress toward resuming normal service. Officials explained that the grounding decision was made to ensure passenger safety as they addressed the technical fault.
Flight tracking service FlightAware showed nearly 1,000 delays into Wednesday night, reflecting the ripple effect of the interruption. United clarified that the issue related specifically to aircraft “weight and balance” systems—critical for ensuring safe departures.
The disruption led to ground stops across several of United’s major hub airports, including Chicago, Newark, San Francisco, Houston, and Denver.
United emphasized that safety remained its top priority throughout the incident and noted that teams were working with travelers to minimize further delays and inconvenience.
