The Federal Aviation Administration (FAA) issued a notice to air missions on January 16,2026,prohibiting U.S. operators from flying over portions of Mexican and South American airspace. The restrictions are effective immediately.
Affected airspace
- Mexico: The FAA prohibits flights below Flight Level 260 (approximately 26,000 feet) over a large section of northern Mexico, citing potential conflicts with military activity. Specific coordinates are not publicly available but cover a meaningful area along the U.S.-Mexico border.
- Venezuela: The FAA expanded its existing prohibition on flights over Venezuelan airspace. Flights are now restricted below Flight Level 280 (approximately 28,000 feet) throughout the country, citing concerns about the stability of air traffic control and potential for unauthorized military interference.
- Guyana: The FAA issued a new prohibition on flights below Flight Level 250 (approximately 25,000 feet) over Guyana, citing ongoing military exercises.
FAA Justification
The FAA did not explicitly state the nature of the military activity prompting the restrictions. However, a statement released by the agency indicated the prohibitions were enacted “to ensure the safety of American operators and passengers.” The timing of the warnings coincides with increased U.S. military presence in the region, according to reporting by Reuters.
Previous FAA Actions
This is not the first time the FAA has issued such warnings. in February 2023, the agency issued a similar notice regarding Venezuelan airspace following reports of close encounters between commercial aircraft and Venezuelan military jets. The FAA also issued temporary flight restrictions over the Gulf of Mexico in January 2024 for military exercises,impacting both commercial and private aviation.
Impact on Airlines
Airlines are rerouting flights to avoid the restricted airspace, which is adding to flight times and fuel costs.American Airlines reported an average increase of 15-20 minutes on flights between Miami and several South American destinations. United Airlines has not yet quantified the impact but confirmed it is adjusting flight paths.
The FAA will continue to monitor the situation and will issue updates as necesary. Operators can find the latest facts on the FAA’s website: https://www.faa.gov/
