FAA Issues 60-Day Caution: What Military Activity Means for Latin America Flights

The United States Federal Aviation Administration (FAA) has issued a formal flight advisory. This advisory urges U.S. air carriers to exercise heightened vigilance when flying in parts of Latin America. The warning was issued on January 16, 2026, via a series of Notices to Airmen (NOTAMs).

Details of the 60-Day Advisory

The advisory is a 60-day flight caution, remaining in effect through March 17, 2026. The affected area is broad, covering significant portions of the Eastern Pacific Ocean airspace. Specifically, the NOTAMs span airspace associated with Mexico, Central America, Colombia, Ecuador, and Panama. The FAA cited two primary risks for commercial aviation operations. These risks are ongoing military activities and potential Global Navigation Satellite System (GNSS) interference.

Risk to Flight Operations

The FAA warned that potential risks exist for aircraft at all altitudes. This includes the critical phases of flight: overflight, arrival, and departure. GNSS interference, which includes GPS, can disrupt navigation systems. Such disruptions pose a significant threat to flight safety and operational integrity. The cautionary guidance applies mainly to U.S. air carriers and U.S.-registered civil aircraft.

Impact on Commercial Aviation

Commercial airlines operating routes to and from South America are reviewing their procedures. Carriers must implement new risk mitigation strategies. This may include carrying extra fuel or adjusting flight paths to avoid the most volatile areas. The advisory follows reports of heightened regional tensions. One incident in December 2025 involved a JetBlue aircraft and a U.S. Air Force tanker. The tanker was reportedly operating without a transponder in the region. This kind of unannounced military activity creates collision risks for civilian aircraft.

• The International Air Transport Association (IATA) stresses the need for clear communication.
• Coordination between military and civil air traffic control is essential for airspace security.
• Airlines must ensure pilots are fully briefed on potential navigation risks.

Mexico's government stated the FAA notice is preventive. They insisted there are no operational restrictions for Mexican airspace or carriers. However, the FAA Notices to Airmen (NOTAMs) serve as a critical safety signal for the entire industry.
