Systems are coming back online now and flights are departing again," an American Airlines spokesperson said. "We put a temporary ground stop in place while our teams worked to resolve the issue. On social media, the company was busy replying to customers seeking information about the issue, telling those individuals they were dealing with a “systemwide IT outage."
