United Flights Temporarily Grounded Over Computer Glitch

All United flights were held for over an hour over an "automation" problem.

United Airlines flights were prevented from taking off for over an hour Wednesday morning after the Federal Aviation Administration placed a hold on the flights because of "automation issues."

An FAA spokesman confirmed the ground stop and said the issue was with the airline's computers.

"We experienced a network connectivity issue this morning," a United spokesperson said in a statement. "We are working to resolve this and apologize to our customers for any inconvenience."

The stop began at about 8:30 this morning. United's subcarriers and regional carriers were released from the hold at about 9:15 a.m. The airline's "mainline" flights—its larger, United-branded flights—were affected until the stop was lifted at 10:50 a.m.

The airline's stocks dropped 1.6 percent this morning.

United experienced a similar glitch last month, when a similar "automation issue" grounded flights for about 40 minutes. The issue then was attributed to the airline's dispatch system.
