American Airlines flights resumed Tuesday evening after a brief nationwide departure halt. An information technology outage caused the Federal Aviation Administration to issue a ground stop. This issue delayed hundreds of flights across the United States for several hours. The airline confirmed systems were coming back online and flights were departing again. Customers experienced inconvenience due to the temporary disruption and its widespread effects.

An American Airlines IT outage disrupted its app and website, prompting the FAA to issue a ground stop for all non-airborne flights Tuesday.

American Airlines flights not in the air were being held for a nationwide ground stop Tuesday evening because of an IT outage, according to an FAA advisory.

Though the ground stop was brief, the ripple effect of halting all planes from such a large carrier will take some time to fully dissipate.
