American Airlines resumed flight departures after a brief but disruptive IT outage forced a nationwide ground stop across the United States on Tuesday evening. The Federal Aviation Administration (FAA) issued the ground stop after a technology failure affected the airline's operational systems.
According to an advisory from the FAA's Air Traffic Control System Command Center, the outage impacted all airports and facilities handling American Airlines operations. Flights already in the air continued to their destinations, but aircraft waiting to depart were held on the ground.
