United Airlines Grounds Flights Over Connectivity Issue
United Airlines temporarily grounded all departing flights in the United States and Canada late Tuesday, Sept. 23, after what it described as a “brief connectivity issue.” The incident, which occurred just before midnight Central time, marked the second time in two months that the airline has issued such an order.
In a statement to USA TODAY, United said that the disruption was short-lived and operations resumed not long after the issue was identified. “United experienced a brief connectivity issue just before midnight Central time on Tuesday, Sept. 23 but has since resumed normal operations,” the airline said in its email response.
At this time, it remains unclear whether the ground stop led to any significant delays or cancellations for passengers. United and the Federal Aviation Administration (FAA) have not provided additional details regarding the scope or impact of the incident.
A Pattern of IT-Related Disruptions
The grounding is the latest in a series of technology-related interruptions affecting major U.S. airlines. On Aug. 6, United issued another ground stop that impacted departures from major hubs including Chicago, Denver, and Houston. That disruption lasted for several hours but was ultimately resolved the same day.
Transportation Secretary Sean Duffy commented at the time, stressing that the August incident was “specific to United’s operations and is unrelated to the broader air traffic control system.”
Other airlines have faced similar challenges in recent years. In July, Alaska Airlines grounded its flights for approximately three hours due to an IT outage. That marked the second such event in just over a year for the carrier. In April 2024, Alaska Airlines suspended operations after a failure in the system responsible for calculating aircraft weight and balance.
Growing Concerns About Airline Technology
Frequent disruptions like these raise questions about the resilience of airline technology systems and the ripple effects they can have on travelers nationwide. Even short outages can create hours-long delays, affect crew scheduling, and leave passengers stranded at airports.
Industry analysts note that as airlines continue to rely on interconnected digital systems for everything from ticketing to flight planning, the risk of cascading failures increases. Some disruptions may be isolated to one carrier, as was the case for United and Alaska, while others—such as the nationwide FAA outage in January 2023—can affect nearly all U.S. air travel.
What Passengers Should Know
So far, United has emphasized that normal operations have resumed following Tuesday’s brief grounding. Still, passengers are encouraged to check the status of their flights on the United app or website, particularly if they were traveling late on Sept. 23 or in the early hours of Sept. 24.
While the airline has not confirmed whether compensation or rebooking assistance will be offered, travelers typically have options in cases of extended delays, including refunds or rebooking at no additional charge.
Looking Ahead
As United and other carriers navigate the growing complexities of digital infrastructure, ensuring the reliability of their systems remains a top priority. Passengers, meanwhile, may see more of these temporary disruptions as airlines work to modernize their technology and respond to new challenges.
For now, United is assuring customers that flights are back on schedule and operations have stabilized following the Sept. 23 ground stop.
