Computer systems restored after 'technical issue' causes outages at airports across the country

Customers at airports across the United States reported long lines and frustrating wait times after a computer system used by multiple carriers went down on Monday afternoon, though the company behind the system says its service is now back online.

Sabre, a Texas-based software and data-solutions firm, has apologized for delays caused by the outage of its computer systems — which are used by carriers including American Airlines, JetBlue and Alaska Airlines for bookings and reservations, and described as helping the carriers "serve their passengers and operate efficiently."

"Systems are back online and customers are reporting normal or close to normal operations," Sabre tweeted just before 3 p.m. on Monday. "We sincerely apologize for any resulting travel delays."

American Airlines, too, apologized to passengers affected by the temporary outage of its Sabre systems.

"Earlier today, Sabre had a brief technical issue that impacted multiple carriers, including American. This technical issue has been resolved. We apologize to our customers for the inconvenience," a spokesperson stated.

Passengers began reporting of outages in the early afternoon, with some reporting long lines and even "bedlam" as a result of the carriers' computer systems being down.

Representatives for JetBlue and Alaska Airlines were not immediately available to comment on the outages for Fox News.

Sabre also experienced a similar outage in late March, which temporarily delayed passengers and resulted in long lines at multiple major airlines across the country. That outage, too, was resolved within a few hours of systems going offline, though Sabre did not confirm whether March's technical outages were related to Monday's.

On its website, Sabre, which is based in Texas, describes itself as a “software and data solutions to help airlines market themselves, sell their products in both the direct and indirect channels, serve their passengers and operate efficiently.”
