The Federal Aviation Administration enforced a nationwide ground stop for all American Airlines flights beginning at approximately 6:29 p.m. Eastern Time on July 28, 2026, after a systemwide IT outage impaired the airline’s operational connectivity. The ground stop was lifted at about 8:10 p.m. ET, allowing flights to resume across the United States.
FAA Ground Stop Procedures and Scope
The FAA’s Air Traffic Control System Command Center coordinated the ground stop, which applied to American Airlines’ mainline and subsidiary operations. The stop mandated that affected American departures remain at their origin airports until the issue was resolved, but it did not impact airborne aircraft. After lifting
the nationwide restriction, localized ground stops continued at Charlotte Douglas International Airport, covering American flights from all gate facilities, and Miami International Airport, narrowly affecting American mainline departures. These localized stops were categorized by the FAA as “Other / Carrier Request.”
Flight Operations and Delays
Flight tracking data confirmed that American Airlines flights resumed departures shortly after 7 p.m. ET, including AA100 from New York John F. Kennedy International Airport to London Heathrow Airport departing at 7:24 p.m. ET and AA1069 from Pittsburgh International Airport to Miami International Airport at 7:47 p.m. ET. Despite the resumption, flights previously held faced departure queues, gate congestion,
and disrupted passenger connections.
Average ground delays at Charlotte Douglas International Airport increased from 24 to 49 minutes during the disruption. The FAA noted a 30% to 60% possibility that localized ground stops at Charlotte could extend beyond their initially scheduled end times.
Official Statements and System Restoration
American Airlines acknowledged the IT outage in an official statement: “A technology issue briefly impacted connectivity for some of our systems on Tuesday evening.” The airline confirmed that system connectivity was fully restored following the disruption and apologized for the inconvenience. “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,” the statement added. The FAA issued advisories describing the initiation and eventual reduction of the ground stop to localized restrictions and clarified that ground stops are traffic management tools and not related to any airworthiness issues.
Passenger Impact and Concurrent Disruptions
Passengers experienced delays and cancellations across American Airlines’ U.S. network during the outage. Those traveling through Charlotte and Miami airports were especially affected by ongoing ground stops and extended wait times. Concurrently, multiple Northeast and Mid-Atlantic airports including Boston Logan International Airport, Newark Liberty International Airport, Philadelphia International Airport, Baltimore/Washington International Airport, Ronald
Reagan Washington National Airport, New York LaGuardia Airport, and New York John F. Kennedy International Airport were subject to weather-related ground stops and delay programs due to thunderstorms, further complicating the impact assessment of the airline’s IT outage.
American Airlines advised travelers to monitor flight status using its tools and mobile applications ahead of airport arrivals, particularly for flights involving Charlotte, Miami, and the Northeast and Mid-Atlantic regions.
Unknown Details and Context
The precise cause of the IT outage, the exact affected systems, and whether any third-party vendor or cybersecurity event was involved were not disclosed by American Airlines or the FAA as of
the reporting cutoff. The FAA did not confirm the coverage of regional affiliate operators under the ground stop. Additionally, no connection has been established between this disruption and a separate nationwide technical interruption American Airlines experienced on December 24, 2024.
No tally of delayed or canceled flights attributed exclusively to the IT outage has been provided, given the overlay of unrelated weather disruptions and air traffic programs on the same day.
