The Mexican government said there has been "no impact whatsoever on civil aviation nor any changes to operating conditions in national airspace," following a notice issued by the U.S. Federal Aviation Administration.

The U.S. Administration has alerted airlines to potential risks, advising them to "exercise caution" over Mexico and several other Latin American countries, due to "military activities," on January 16 local time.  

Mexico responded that "there are no operational implications or restrictions for Mexico, nor for Mexican airlines or operators."
