American Airlines Resumes Flights Nationwide After Brief IT Issue Caused FAA Ground Stop

American Airlines grounded all of its flights nationwide on Tuesday evening after a technology issue knocked out key systems. The Federal Aviation Administration issued a ground stop for the airline, delaying hundreds of planes across the country. Flights began moving again after the issue was resolved, with the ground stop officially lifted at 7:18pm ET, according to Free Malaysia Today.
By the time operations resumed, the damage was already done. American Airlines had delayed roughly 1,100 flights — about 30% of its schedule — and canceled 221 others, or 6% of all planned departures. The disruption came on a night when many US East Coast airports were already struggling with significant delays caused by thunderstorms.
The FAA issued a nationwide ground stop for American Airlines and its regional partner carriers after an IT issue hit the airline's systems on Tuesday evening. A ground stop means no planes are allowed to take off. The order affected every American Airlines departure in the country, not just certain airports or routes, according to KOMO News.
The ground stop was in effect for less than an hour. American Airlines reported the issue was resolved shortly after 6:30pm ET, and the FAA formally canceled the order at 7:18pm ET. The airline and its regional carriers then began resuming departures, according to WACH.
The ripple effect was significant. American Airlines delayed 1,100 flights, representing 30% of its entire evening schedule. Another 221 flights, or 6% of all departures, were outright canceled. Even a short ground stop can create hours of downstream delays as planes and crews fall out of position across the network, according to WUTV29.
The timing made things worse. Major East Coast airports were already dealing with heavy thunderstorm delays before the ground stop hit. Passengers at airports like those along the Eastern Seaboard faced a double hit — weather delays stacking on top of the system-wide technology freeze, according to WGXA.
American Airlines confirmed that a technology issue impacted its systems but did not provide details about what exactly failed or why. The airline has not said whether the outage was caused by a cyberattack, a software glitch, or a hardware problem. ABC6 reported that the airline said the issue was resolved without giving further specifics.
This is not the first time a major US airline has suffered a technology-driven ground stop. Such outages can stem from failures in dispatch systems, crew tracking software, or communications tools. Any one of these can trigger a safety hold that grounds the entire fleet until the problem is fixed.
Operations restarted after the ground stop was lifted just before 7:30pm ET. But getting back to a normal schedule takes time. Planes need to be repositioned. Crews that hit legal work-hour limits may need to be swapped out. Passengers who missed connections face rebooking. The full recovery could stretch well into Wednesday, according to WUTV29.
Travelers affected by the disruption should check their flight status directly with American Airlines. The airline typically offers fee-free rebooking during large-scale operational disruptions. Anyone with a canceled flight is generally entitled to a full refund if they choose not to rebook, under US Department of Transportation rules.
