Travelers faced disrupted services as boarding passes, check-in apps, baggage, and gate systems went down, and flight plans could not be pushed to aircraft.

The airline has not disclosed a specific cause for the tech issue, describing it as a system-wide outage.

More than 1,500 users reported app problems on Downdetector by late afternoon, underscoring the scale of the outage.

Analysts noted that airline operations rely on integrated software for crew scheduling, weight-and-balance, and other functions, making them vulnerable to single-point failures and highlighting resilience needs.

Passengers on the tarmac and at gates reported frustration and long wait times, according to social media posts.

Industry observers expect disruption to linger for days as schedules stabilize and scrutiny focuses on root causes and IT modernization efforts.

The story is evolving and will be updated as more details become available, with the latest report posted on the evening of July 28, 2026.

Updates note ongoing disruption and that new information has been added as the situation develops.

Travel guidance for affected passengers includes monitoring status across multiple sources, arriving early, considering alternative routings, and contacting airline channels promptly for rebooking or refunds.

Flight tracking showed substantial delays in arrivals and departures, reflecting the operational impact of the outage.

American Airlines restored flights after a nationwide IT outage that had caused a ground stop and widespread system failures.

Airport authorities cautioned that delays and cancellations could continue and urged travelers to verify latest information with airlines.
