Computer glitch temporarily grounds all United Airlines flights in U.S.

United Airlines temporarily grounded all flights in the U.S. Wednesday morning due to computer problems.

In Pittsburgh, the carrier had 15 departures and 16 arrivals scheduled from 9 a.m. through 8 p.m.

Around 9 a.m. United Airlines had grounded all mainline operations due to a computer glitch in the system, said a spokesperson for Pittsburgh International Airport. Around 10 a.m., the FAA order was lifted.

United said in a statement that it was working to resolve the problems, which are related to “network connectivity.”

“We are recovering from a network connectivity issue this morning and restoring regular flight operations,” the statement said. “We will have a waiver available at for customers who are able to change their flight plans.”

It is the second time in two months that the Chicago carrier has been hit by major technical issues.

United had a temporary halt to all takeoffs in the U.S. on June 2 because of what the airline said were computer automation issues.

You are solely responsible for your comments and by using you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
