United Says Hardware Issue Caused Outage
United Airlines says 580 flights were delayed Tuesday because a piece of computer equipment failed to communicate correctly, and its backup system didn't work as expected.
The failure shut down United's website for more than two hours and prevented workers from boarding passengers on time. United passengers reported long lines in the airline's hubs in Newark, N.J., San Francisco, Houston, and Chicago. It also caused nine cancellations.
United Continental Holdings Inc. said Wednesday that it's still working to find out why the computer equipment didn't work right. The problems came on the same day that airlines already had to deal with Hurricane Isaac, which has disrupted travel in cities around the Gulf of Mexico.
