United Airlines System Outage Causes Major Flight Delays Across U.S.
By USA NEWS TODAY, 07 August 2025
United Airlines experienced a major system outage on Wednesday, triggering widespread flight delays and cancellations across airports in the United States. The technical failure, which began early in the morning, disrupted operations nationwide, leaving thousands of travelers stranded and frustrated.
According to initial reports, the outage affected the airline’s internal systems responsible for dispatching flights and coordinating crew schedules. Passengers at key hubs such as Chicago O’Hare, Newark Liberty, and Denver International reported long lines, delayed departures, and limited information from staff.
The Federal Aviation Administration (FAA) briefly issued a nationwide ground stop for United flights, which was lifted after the airline began restoring operations. United Airlines later confirmed the issue via a statement, citing a “technology malfunction” but assuring the public that there was no evidence of a cybersecurity breach.
“Our teams have identified a fix and are working to restore normal flight operations as quickly as possible,” United said. “We apologize to our customers for the inconvenience and appreciate their patience.”
As of the latest update, over 350 flights have been delayed, and at least 45 flights were canceled. Travelers are being advised to check their flight status before heading to the airport and to prepare for possible rebookings or overnight delays.
This marks the second significant operational disruption for a major U.S. airline this summer, raising questions about the reliability of airline technology infrastructures and emergency response protocols.
Airline analysts say incidents like this, though rare, highlight the need for modernized IT systems and better contingency planning within the aviation industry.
Affected Airports Include:
Chicago O’Hare International
Newark Liberty International
Denver International
San Francisco International
Houston George Bush Intercontinental
