FAA Issues Cautionary Warnings for Flights Over Eastern Pacific and Latin America

On January 16, 2026, the Federal Aviation Administration (FAA) issued a series of Notices to Airmen (NOTAMs) advising U.S. aircraft operators to "exercise caution" when flying over specific areas of the eastern Pacific Ocean adjacent to Mexico, Central America, and parts of South America. The warnings highlight potential risks associated with increased military activities and possible interference with Global Navigation Satellite Systems (GNSS), which are vital for aircraft navigation. These advisories are set to remain in effect for 60 days.

The FAA's warnings come in the wake of heightened military operations by the U.S. in the region, particularly following a large-scale military campaign targeting alleged drug trafficking vessels in the Caribbean and eastern Pacific. This campaign reportedly included 35 strikes that resulted in at least 115 fatalities. Notably, on January 3, U.S. forces conducted a significant operation that led to the capture of Venezuelan President Nicolás Maduro and his wife, Cilia Flores, who are facing federal drug trafficking charges in the U.S.

The NOTAMs specifically cover airspace over Mexico, Central America, Panama, Bogotá, Guayaquil, and the Mazatlán Oceanic Flight Regions. The FAA's advisory indicates that risks exist for aircraft at all altitudes, particularly during critical phases of flight such as takeoff and landing.

The FAA has not disclosed specific details regarding the motivations behind the recent warnings. However, the timing coincides with ongoing U.S. military operations and a broader strategy to combat drug cartels in the region. President Donald Trump has publicly stated the need for increased military action against cartels, suggesting that U.S. forces may engage in operations on land to dismantle fentanyl labs in Mexico.

There has been some confusion regarding the FAA's warnings, as representatives from the U.S. Special Operations Command and the U.S. Southern Command indicated they were unaware of the FAA's advisories prior to their issuance. This lack of coordination raises questions about the communication between military and aviation authorities during heightened military operations.

While the FAA's warnings are clear, the specific triggers for these advisories remain ambiguous. There have been reports of increased military strikes in the eastern Pacific, but the FAA has not directly linked its warnings to any particular operation or incident. Additionally, the Pentagon has referred inquiries back to the FAA, indicating a potential gap in information dissemination.
