American Airlines system outage grounds flights across the US

American Airlines temporarily grounded all of its flights in the US this morning due to unspecified technical issues, disrupting travel at the start of a busy Christmas Eve. Service has now resumed as of 8AM ET according to a statement American Airlines spokesperson Sarah Jantz provided to CNN.

The airline suffered a massive system outage according to multiple travelers on X who are facing delays, which prevented boarding passes from being scanned and flights from departing. A notice published on the Federal Aviation Administration website at 6.50AM ET said that the airline grounded all flights nationwide. An FAA update posted at 7.50AM ET has since announced that the nationwide groundstop has been canceled.

The airline hasn’t given any details on what caused the technical issues.

“We’re currently experiencing a technical issue with all American Airlines flights,” American Airlines said in a statement on X before flights resumed. “Your safety is our utmost priority, once this is rectified, we’ll have you safely on your way to your destination.”

Update, December 24th: American Airlines flights have now resumed nationwide.
