American Airlines resumed operations just about 8 a.m. ET Tuesday after earlier grounding all flights across the country due to a technical issue, impacting travelers on one of the busiest travel days of the year.
The exact nature of the technical problem and what systems it may have impacted was not immediately disclosed.
An advisory issued by the Federal Aviation Administration showed the company issued a request for a full ground stop of its flights. The stop lasted for exactly one hour, according to the FAA records.
“A technical issue is affecting American flights this morning. Our teams are working to resolve the issue as quickly as possible, and we apologize to our customers for the inconvenience,” the company said in a statement upon issuing the ground stop.
The Transportation Security Administration expects to screen 40 million passengers over the holidays and through January 2, according to The Associated Press.
