American Airlines faced a temporary nationwide ground stop on the evening of July 28, 2026, after an information-technology outage disrupted connectivity across its systems. The Federal Aviation Administration (FAA) imposed the ground stop shortly after 7 p.m. Eastern Daylight Time (EDT) to pause additional American Airlines departures across the United States while the issue was addressed.
By 8:10 p.m. EDT, the FAA’s Air Traffic Control System Command Center had lifted the nationwide ground stop. Flight tracking by FlightAware showed American flights resuming departures, including 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, two airport-specific ground stops persisted: one at Charlotte Douglas International Airport (CLT), covering American mainline and subsidiaries, and a second at Miami International Airport (MIA) affecting American mainline flights. The FAA classified these as “Other / Carrier Request.”
Concurrent with the American Airlines IT outage and ground stops, weather-related restrictions impacted multiple airports in the Northeast and Mid-Atlantic. Boston Logan International Airport (BOS), Newark Liberty International Airport (EWR), and Philadelphia International Airport (PHL) operated under national
delay programs due to thunderstorms. Additional ground stops or delays were reported at Baltimore/Washington International Airport (BWI), Ronald Reagan Washington National Airport (DCA), JFK, New York LaGuardia Airport (LGA), and surrounding general-aviation airports, further complicating air traffic flow in the region.
American Airlines issued statements on social media acknowledging the technology disruption, saying, “A technology issue briefly impacted connectivity for some of our systems on Tuesday evening.” The airline confirmed systems were coming back online and flights were departing again, adding, “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’s Air Traffic Control System Command Center implemented and ended the ground stop as conditions allowed. Passengers were advised by American Airlines to monitor flight status and airline communications, particularly at Charlotte and Miami airports where local ground stops remained in effect after the nationwide pause.
American Airlines has encountered prior IT disruptions, including a brief nationwide outage on December 24, 2024, but no connection between that event and the July 28, 2026 outage has been established. The airline did not disclose the specific system affected, the technical cause, or whether the issue involved
external vendors or cybersecurity incidents before this report. Total flight delays and cancellations attributable solely to the IT outage were not published, partly due to overlapping weather-related operational constraints across affected airports.
