United Airlines experienced a technology disruption on August 6, 2025, that halted departures across key U.S. hubs—including Newark, Denver, Houston, and Chicago. The failure affected the Unimatic system, which tracks flight data essential for load calculations and scheduling. In total, 34% of flights were delayed that day. Operations gradually resumed as the glitch was patched.

Impact During Recovery
The Federal Aviation Administration (FAA) confirmed it assisted in clearing the backlog. Transportation Secretary Sean Duffy emphasized that the issue was unique to United’s systems and did not affect broader air traffic operations. United categorized the incident as a controllable delay and pledged to cover hotel and meal costs for stranded passengers where applicable.
