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.
