United Airlines experienced a technology outage on the morning of July 25, 2026, leading to widespread flight delays across the United States. Passengers began reporting issues before 7:40 a.m., and by 8:23 a.m. over 430 reports had been logged on Down Detector.
Technology Outage Disrupts Check-In and Reservation Systems
The outage impacted United Airlines’ reservation system, disabling contact centers and check-in processes. This prevented passengers from completing check-ins and processing ticket-related transactions. Flights already airborne or that had departed the gate were not affected by the outage.
