The FAA issued a nationwide ground stop for American Airlines and its regional carriers at approximately 6:30 PM Eastern on Tuesday July 28 after a technology issue disrupted the airline's operational systems, halting all departures across the United States during one of the busiest travel evenings of the summer. The ground stop was lifted at 7:18 PM ET and flights resumed shortly after. "A technology issue briefly impacted connectivity for some of our systems on Tuesday evening," American Airlines said in a statement. We put a temporary ground stop in place while our teams worked to resolve the issue. The carrier experienced a similar ground stop on Christmas Eve 2024.
