Dallas police were dispatched to the airport at 8:31 p.m. for a call regarding an aircraft alert, according to authorities. A preliminary investigation found that a threat had been made, but it was later determined to be unfounded. The Federal Aviation Administration had issued an alert concerning the security issue, which led to the airport's temporary closure.

The airport reopened following the investigation. Authorities said the investigation is ongoing, and no injuries have been reported.

The disruption came one day after a nationwide ground stop halted flights across the country Friday, leaving thousands of passengers stranded and airlines scrambling to recover. The back-to-back events compounded travel difficulties for North Texas passengers and highlighted the vulnerability of air travel to both security scares and system-wide disruptions.

Love Field is a major hub for Southwest Airlines and a key economic engine for the Dallas region. Temporary closures can ripple through flight schedules and strand travelers, though the airport's quick reopening Saturday limited the immediate impact.

Police have not released further details about the nature of the threat or the aircraft involved. The investigation remains active.
