The Federal Aviation Administration announced a nationwide ground stop for all American Airlines flights that were not already airborne, citing an information‑technology outage.
The interruption occurred Tuesday evening, prompting authorities to halt departures across the United States while the carrier addressed the problem.
American Airlines reported that a technology issue briefly disrupted connectivity for several of its operational systems, but the systems are now returning to normal.
With systems coming back online, the airline confirmed that flights are beginning to depart again as service resumes.
The carrier issued an apology to passengers, acknowledging the inconvenience caused by the temporary ground stop.
This event adds to a series of recent airline IT disruptions, including a comparable nationwide ground stop that affected another major carrier earlier last year.
Aviation officials emphasized that safety remains the highest priority, and airlines work closely with regulators to restore full operations after such outages.
