Widespread Slowdown in United's Technology Systems Causes Delays


CHICAGO, ILLINOIS — A computer glitch led to a brief halt in United Airlines' US operations on Tuesday. The airline reported that "a software update" was the culprit behind the extensive slowdown in its tech systems. Despite this setback, flights that had already taken off proceeded to their intended destinations without any hitches.

United Airlines acted promptly to address the situation, stating that they had "determined a solution" and were able to restart departures roughly an hour after the disruption began.

The Federal Aviation Administration (FAA) clarified that, upon United's request, they had temporarily halted all of the airline's take-offs across the country. This nationwide ground stop was lifted just before 14:00 EST (19:00 BST).

It was reported that the software malfunction resulted in delays for 211 flights throughout the nation. Notably, this isn't the first time the FAA has experienced such disruptions. In January, a computer outage at the FAA had stopped all US flight departures for a number of hours.
