The Federal Aviation Administration on Friday, January 16, 2026, urged US aircraft operators to “exercise caution” when flying over the eastern Pacific Ocean near Mexico, Central America and parts of South America, citing “military activities” and possible satellite navigation interference.
The warning was issued in a series of Notices to Airmen (NOTAMs) issued by the FAA. They say, “Potential risks exist for aircraft at all altitudes, including during overflight and the arrival and departure phases of flight.” The alerts are in effect for 60 days. Such notices are issued routinely in any region where there are hostilities nearby.
