American Airlines and its regional airlines said they had resumed flight operations on Tuesday evening after a brief suspension of flights across the US due to an IT system failure. The US Federal Aviation Administration issued a grounding order on American Airlines flights at around 6:30 p.m. EST due to an IT system failure. The ban was lifted at 7:18 p.m. The failure caused hundreds of flight delays due to unresolved system failures that prevented the previous aircraft from taking off; at this time, many airports on the east coast of the United States were facing severe delays and grounding due to thunderstorms. “The system is now back in operation and flights have taken off again,” American Airlines said in a statement. “While our team is working to resolve the issue, we have implemented a temporary grounding. We apologize for any inconvenience this may have caused our customers.” According to the flight tracking website FlightAware, American Airlines delayed 1,100 flights on Tuesday, accounting for 30% of the total number of flights that day; another 221 flights were cancelled, accounting for 6%. Another airline website, Flightradar24, said that as of 7 p.m. EST, the number of air flights had decreased by 130 compared to the same period last week.
