American Airlines briefly grounded all its flights nationwide after a system outage disrupted operations, causing widespread delays and cancellations for passengers across the United States. The ground stop highlights the vulnerability of major carriers to technical failures, which can ripple through the entire air travel network and strand thousands of travellers with little warning.

The outage affected the airline's ability to manage flight operations safely, prompting it to halt departures until the issue was resolved. Passengers faced disruption at airports nationwide as the airline worked to restore its systems and get delayed flights moving again.
