Travelers at major airports across the country are reporting on computer outages causing delays across multiple airlines. Passengers began taking to Twitter around 11 a.m. EST on Tuesday, complaining of delayed flights and computer outages affecting American Airlines, Alaska Airlines and JetBlue. American Airlines has since confirmed the outages, attributing them to a "technical issue" caused by the Sabre computer systems, which are used by "multiple carriers." Shortly after 11:30 a.m., the airline stated that the issue had been resolved. "Earlier today, Sabre had a brief technical issue that impacted multiple carriers, including American Airlines. This technical issue has been resolved. We apologize to our customers for the inconvenience."

It's been reported that services such as online banking have been down for some TSB customers for over a week. Many individuals and businesses will have made arrangements for the planned outage, but not for the additional time that the systems have been unavailable.

Davis says the computer system is regularly backed up, and workers are using that information to restore the system to its condition prior to Friday. When the system returns, he says paper filings made in the meantime will have to be added.
