The Federal Aviation Administration (FAA) imposed a nationwide ground stop on all American Airlines departures on Tuesday evening, July 28, 2026, starting around 6:29 p.m. Eastern Time. The pause was prompted by a systemwide information technology outage affecting American Airlines operations.
American Airlines confirmed the outage with a spokesperson noting, “a technology issue briefly impacted connectivity for some of our systems on Tuesday evening.” The airline stated that flights began departing again as systems were restored, apologizing for the inconvenience caused.
Ground Stop Lifted, Airline Resumes Flights with Local Restrictions Remaining
The FAA Air Traffic Control System Command Center lifted the nationwide ground stop by 8:10 p.m. ET, as confirmed
by flight tracking service FlightAware, which showed resumed 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 resuming flights nationwide, two localized ground stops persisted at Charlotte Douglas International Airport (CLT) and Miami International Airport (MIA). The CLT ground stop applied to American Airlines’ mainline and subsidiaries, while the MIA stop targeted mainline departures only. The FAA classified these as “Other / Carrier Request” with possibilities of extension between 30% and
60%, indicating ongoing congestion issues.
Operational Impact and Concurrent Weather Delays
Delays and backlog intensified post-ground stop at Charlotte Douglas International Airport, where average departure delays increased from 24 to 49 minutes. American Airlines flights inbound to CLT were held at origin airports due to congestion.
Simultaneously, multiple major Northeast and Mid-Atlantic 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), New York LaGuardia Airport (LGA), and JFK were affected by weather-related ground stops and delay programs attributed to thunderstorms. These concurrent restrictions complicate isolating the impact solely caused
by American Airlines’ IT outage.
Official Statements and FAA Ground Stop Procedures
American Airlines issued statements confirming system connectivity was restored and flights resumed. An airline spokesperson stated, “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.” Another statement added, “Connectivity has been fully restored. We appreciate the efforts of our team to bring our systems back online so quickly and take care of our customers.”
The FAA explains ground stops are operational controls managed by the Air Traffic Control System
Command Center in cooperation with regional facilities and industry partners. These stops prevent departing flights from entering the airspace system but do not recall aircraft already airborne.
Unknowns and Further Clarifications Pending
Details on the specific IT systems affected, the root cause of the outage, vendor involvement, or any cybersecurity links remain undisclosed as of the latest reports. The FAA and American Airlines have not released delay or cancellation totals attributed solely to the outage.
No association has been established between this incident and a separate American Airlines IT problem that caused a nationwide ground stop on December 24, 2024. Additionally, speculation regarding involvement of
vendors such as CrowdStrike, T-Mobile, or data center failures are unconfirmed and should not be linked to this event without official information.
Passengers continuing travel through Charlotte Douglas International Airport, Miami International Airport, or Northeast and Mid-Atlantic airports affected by thunderstorms on July 28, 2026, may experience residual delays.
