American Airlines faced a nationwide ground stop ordered by the Federal Aviation Administration shortly after 7 p.m. EDT on July 28, 2026, after an information-technology issue disrupted its systems connectivity. The FAA’s Air Traffic Control System Command Center issued the restriction to halt departures across the airline’s network.
By 8:10 p.m. EDT, the FAA lifted the nationwide ground stop, allowing American Airlines to resume flight departures. Flight-tracking data confirmed post-7 p.m. departures including AA100 from New York John F. Kennedy International Airport (JFK) to London Heathrow Airport (LHR) at 7:24 p.m., and AA1069 from Pittsburgh International Airport (PIT) to Miami
International Airport (MIA) at 7:47 p.m., signaling a restart of operations.
Residual Ground Stops at Charlotte and Miami Airports
Despite the nationwide ground stop lifting, the FAA reported two residual ground stops affecting American Airlines at 8:10 p.m. One applied to all American mainline and subsidiary departures at Charlotte Douglas International Airport (CLT), while the other impacted American mainline flights from Miami International Airport (MIA). The FAA categorized both as “Other / Carrier Request.” The FAA did not clarify whether these residual stops were linked to the earlier IT outage or stemmed from gate or traffic management issues.
Concurrent Weather-Related Air Traffic Restrictions
Simultaneous to the IT outage and ground stops, weather-related air
traffic restrictions affected several Northeast and Mid-Atlantic airports, including Boston Logan International Airport (BOS), Newark Liberty International Airport (EWR), and Philadelphia International Airport (PHL). Departure delays and ground stops due to thunderstorms were also in effect at Baltimore/Washington International Airport (BWI), Ronald Reagan Washington National Airport (DCA), JFK, and New York LaGuardia Airport (LGA). These overlapping weather restrictions complicate isolating the IT outage’s direct impact on American Airlines flight disruptions.
Details on the IT Outage Cause Remain Limited
The ground stop was attributed to an IT outage that impaired American Airlines’ system connectivity. The airline acknowledged the technical issue briefly impacted some systems and apologized for the inconvenience,
stating that systems were coming back online and flights had resumed. However, American Airlines did not disclose which specific systems failed, the cause of the disruption, or whether the incident involved any external vendors or cybersecurity events.
Passenger Impact and Operational Context
The FAA ground stop prevented departures but did not affect aircraft already airborne. Flights delayed during the stop faced queues at departure gates, with ongoing challenges including gate availability and passenger connections once restrictions ended. Travelers passing through Charlotte Douglas and Miami airports could still encounter residual delays linked to the remaining airport-specific ground stops.
American Airlines previously experienced a separate nationwide technical
outage on December 24, 2024, unrelated to the current event. The FAA’s use of ground stops serves as a traffic management tool and does not equate to an airworthiness grounding of aircraft types. The agency has not provided additional explanations on the July 28 IT outage duration or cause beyond the ground stop order and lifting.
