According to the airline, the computer issues have been resolved. Although it is unclear when American's planes will return to service.
"We have resolved connectivity issues that led to a ground stop today at our Chicago, Dallas/Fort Worth and Miami hubs," American Airlines told Business Insider in an emailed statement.
"We apologize for the inconvenience and are working to get our customers on their way as soon as possible."
Earlier reports indicated a nationwide ground stop, but the FAA ground stop was actually more limited.
The action has affected departing American Airlines flights out of Dallas/Fort Worth, Chicago O'Hare, and Miami International airports.
The FAA ground stop is expected to last until 2:30 p.m. Eastern Time, CNBC reported.
Today's incident is the latest in a series of computer-related delays to hit US airlines.
Earlier this year, United Airlines experienced two computer glitches a month apart from each other that forced the carrier to ground its flights.
We'll update when more information is available.
