American Airlines faced a temporary nationwide ground stop on July 28, 2026, shortly after 7 p.m. EDT, after an information-technology failure disrupted the carrier’s operations. The Federal Aviation Administration’s Air Traffic Control System Command Center issued the ground stop, halting all new American Airlines departures across the United States while the issue was addressed.
By 8:10 p.m. EDT, the FAA lifted the nationwide ground stop, enabling American Airlines flights to resume. According to flight tracking data, flights departed again soon after, reflecting the FAA’s coordination in ending the restriction and restoring operations.
Notable post-ground stop departures included flight AA100 from
New York John F. Kennedy International Airport (JFK) to London Heathrow Airport (LHR) at 7:24 p.m., and flight AA1069 from Pittsburgh International Airport (PIT) to Miami International Airport (MIA) at 7:47 p.m. Despite the nationwide stop ending, the FAA maintained two American-specific ground stops at Charlotte Douglas International Airport (CLT) affecting both mainline and subsidiary operations, and at Miami International Airport (MIA) applying to mainline flights only. The FAA classified these as “Other / Carrier Request.”
Simultaneously, weather-related air traffic restrictions complicated operations across the Northeast and Mid-Atlantic regions. Airports including Boston Logan International Airport (BOS), Newark Liberty International Airport
(EWR), Philadelphia International Airport (PHL), Baltimore/Washington International Airport (BWI), Ronald Reagan Washington National Airport (DCA), JFK, and New York LaGuardia Airport (LGA) were subject to thunderstorm-related ground stops and departure delay programs.
The IT outage ground stop affected departures but did not recall aircraft already airborne. Flights held during the stop faced subsequent delays, disrupted connections, and congestion for gates and crews upon arrival. Passengers traveling through affected airports, such as Charlotte and Miami, experienced ongoing delays following the lifting of the nationwide restriction.
American Airlines disclosed a similar nationwide IT outage on December 24, 2024. However, there is no
evidence linking that event to the July 28, 2026 disruption. The airline has not revealed which computer systems failed, nor detailed the cause or duration of the July outage.
In an official statement, American Airlines said: “A technology issue briefly impacted connectivity for some of our systems on Tuesday evening. Systems are coming back online now and flights are departing again. We put a temporary ground stop in place while our teams worked to resolve the issue. We apologize to our customers for the inconvenience.” The FAA noted that ground stops are standard traffic management tools implemented with collaboration among
FAA facilities and airlines to hold departures until issues are resolved.
Additional information remains undisclosed regarding the affected systems, cause of failure, number of delayed flights, and any connection to vendor or cybersecurity factors. The relationship between the two residual airport-specific ground stops and the main IT outage also has not been confirmed, nor has the overall impact beyond the reported timeframe.
