Cybersecurity firm CrowdStrike said that the issue believed to be behind the outage was not a security incident or cyberattack - and that a fix was on the way.
The company said the problem occurred when it deployed a faulty update to computers running Microsoft Windows. Early Friday morning, American Airlines was working with CrowdStrike to resolve issues impacting their flights. As of 3 a.
m., the airline reported they were able to safely re-establish their operations, the airline said. United Airlines also saw impacts from the computer outage.
As of 3:20 a.m., the airline was resuming some flights but expected disruptions to continue throughout the day.
United was offering a waiver to make it easier for customers to change their travel plans, either on united.com or through the United app. Anyone traveling through the airport this morning should check with their airline on the status of their flight.
