American Airlines flight AAL3160, which took off from Chicago, landed at Philadelphia International Airport on 9 August 2026, affecting United States airspace. It was a Boeing 737-800, with the serial number N972AN, departing Boston Logan International Airport for Chicago O’Hare at 9:35 pm EDT. But this plan was modified due to an American Airlines flight diversion, and the aircraft diverted to another airport in the United States.

What happened to American Airlines Flight AAL3160 during its journey?

According to FlightAware and Flightradar24, American Airlines flight AAL3160 was scheduled to operate from Boston Logan International Airport in Massachusetts to Chicago O’Hare International Airport in Illinois on 9 August 2026. The flight was operated by a Boeing 737-800 aircraft registered N972AN, which departed Boston at approximately 10:07 PM local time after its scheduled departure time of 7:17 PM.
