Power Outages, United Ground Stops Cause Widespread Flight Delays at Multiple U.S. Airports

Multiple airports across the U.S. experienced significant flight delays due to technical issues this week. McGhee Tyson Airport in Alcoa, Tennessee, faced restricted operations and delayed flights following a power outage caused by an electrical issue, with repairs ongoing and passengers advised to check with airlines for updates. Similarly, United Airlines implemented a ground stop at Houston's Bush Intercontinental Airport due to a technical problem, resulting in delays from the evening until the ground stop was lifted. Newark Liberty International Airport saw widespread disruptions after a nationwide system outage affected United Airlines' Unimatic system, grounding all departing flights and delaying approximately 1,100 flights nationwide, with delays expected to continue into the weekend. The FAA confirmed no cyberattack was involved, and United Airlines is offering accommodations and fee waivers while working to resolve the backlog. Travelers are encouraged to stay informed through their airlines as operations recover at these affected airports.
