(MEXICO) — The FAA just issued a 60-day flight caution that can change your routing, timing, and even misconnect risk on flights over the eastern Pacific and parts of Latin America. If you’re flying between the U.S., Mexico, Central America, and northern South America, expect more reroutes and longer flight plans.
If you’re chasing miles or elite status, those detours can also mean fewer flight segments and less predictable arrival times.
The Federal Aviation Administration issued the caution on Friday, January 16, 2026. It runs for 60 days and expires March 17, 2026. The agency is warning U.S. operators about an elevated risk environment tied to military activity and possible satellite navigation interference.
It’s communicated through Notices to Airmen (NOTAMs), which airlines and crews use for real-time operational decisions.
1) Overview of the FAA 60-Day Flight Caution
A flight caution is not a blanket flight ban. It’s a formal “pay attention” notice to airlines, dispatchers, and pilots that signals elevated operational risk in a defined region.
That matters because dispatchers may change routings, add fuel, or pick different alternates. Crews may also brief for navigation anomalies and unexpected traffic.
This caution focuses on corridors over the eastern Pacific near Mexico, Central America, and parts of South America. The scope can affect overflights, arrivals, and departures, and it can apply at all altitudes depending on NOTAM language.
In practice, that means everything from cruise-level overwater tracks to descent and approach paths can be in play.
The hazard themes are straightforward:
- Increased military activity in the region’s air and maritime environment.
- Possible satellite navigation interference, which can degrade GPS-based navigation.
This comes after earlier FAA attention to similar risks. Travelers may remember the agency’s prior warnings tied to the region, including Venezuela airspace.
Before/After: What changes for travelers?
This is a policy shift in risk posture, not a new fee or fare rule. Still, it changes how your trip may operate.
| Before (typical operations) | After (during FAA caution period) | |
|---|---|---|
| Routing | More direct tracks when winds allow | More reroutes around risk areas, sometimes longer |
| Block times | Scheduled times usually match historical averages | More padding, airborne holds, or longer flight plans |
| Navigation environment | Lower expectation of GNSS issues | Higher alert for possible interference and procedural backups |
| Irregular operations | Mostly weather/ATC-driven | Added layer of security-driven route changes and alternates |
📅 Key Date: The FAA caution was issued Jan. 16, 2026, and is set to expire March 17, 2026 (a 60-day period).
2) Duration and format: Why this shows up as NOTAMs
NOTAMs exist for situations that can shift fast, including airspace constraints, conflict-related risks, temporary restrictions, and navigation disruptions. Airlines ingest them into dispatch planning tools, then push key items to crews through briefings and cockpit data links.
This caution is time-bounded. It also can be amended, canceled, or reissued. That’s why the “headline” dates are not the whole story. The most important habit during a caution period is checking for updates.
Dispatchers do this before release, and crews re-check during preflight. Many carriers also monitor en-route changes through datalink messages and ATC advisories.
Operationally, here’s how it usually works:
- Dispatch incorporates NOTAMs into the flight release and risk assessment.
- Crews review the packet and NOTAM excerpts during preflight.
- Updates get pushed via ACARS or EFB syncs.
- ATC may add tactical reroutes when traffic or restrictions change.
If you’re a passenger, this is why a “routine” route can suddenly change. It may happen after you board and can also happen mid-flight.
⚠️ Heads Up: During a caution window, the “same flight number” can fly different tracks on different days. That can swing block times and connections.
3) Triggering context and why escalation matters
The FAA’s caution follows a rising security backdrop in the region. The administration has cited four months of U.S. military strikes against suspected drug-trafficking boats, reporting 35 confirmed operations and at least 115 deaths.
There was also a major escalation on Jan. 3, 2026. The U.S. conducted a large-scale strike in Caracas that resulted in the seizure of President Nicolás Maduro and Cilia Flores. They were transported to New York for federal drug trafficking charges.
Why does this matter for civilian flights? Because higher military activity can change the operating picture quickly:
- Airspace can be restricted with little notice.
- Military aircraft may operate near civilian corridors.
- Communications can get busier and more complex.
- Reroutes can stack up, creating delays and congestion.
Satellite navigation interference is the other big operational hazard. In plain terms, GNSS issues can show up as unreliable GPS position, weird map shifts, or alerts about lost integrity.
Crews can revert to inertial systems, ground-based aids, and stricter cross-checks. But it increases workload and can limit which approaches are comfortable in marginal weather.
A practical example: In December 2025, a JetBlue flight from Curaçao aborted its ascent to avoid a U.S. Air Force refueling tanker. That’s the kind of “wrong place, wrong time” scenario cautions are meant to reduce.
This broader trend is also part of the industry’s ongoing shift toward geopolitical risk planning, which has been shaping network decisions and costs across carriers. That theme is explored in geopolitics and ops risks.
4) Operational guidance for pilots (and what it means for passengers)
For flight crews and dispatch teams, the caution translates into very specific habits around monitoring, planning, and reporting.
Monitoring and updates include:
- Check NOTAMs before departure and after gate changes.
- Use dispatcher uplinks and ACARS messages for mid-flight updates.
- Refresh EFB data when connectivity allows.
- Treat ATC advisories about activity or routing as time-sensitive.
Planning and mitigations include:
- Consider more conservative routings around affected corridors.
- Carry contingency fuel when reroute probability is higher.
- Brief alternates with strong ground-based nav support.
- Review “nav interference” callouts and cross-check procedures.
Escalation and reporting steps:
- Report irregularities to ATC when safety or separation could be affected.
- Use company safety reporting for suspected interference.
- Coordinate early with dispatch if the route starts “moving” in-flight.
For travelers, the effect is usually indirect but real: longer flights can mean missed connections, and crews can time out after delays, triggering cancellations.
If you’re connecting, leave more buffer than usual. A 35-minute domestic-to-international connection can be fine on paper but fragile when routings change overwater.
5) What airlines and routes are most affected
This FAA 60-day flight caution hits airlines hardest when they’re operating:
- West Coast–Mexico and West Coast–Central America routes.
- Texas–Mexico and Texas–Central America routes that swing over the eastern Pacific.
- Some South America routings that avoid the Caribbean.
Airline operations teams may respond with preferred route updates, altitude strategies, dispatch checklist changes tied to NOTAM monitoring, and more conservative alternates and fuel planning.
Customer operations teams may also plan for disruptions with more proactive reaccommodation or preemptive schedule padding. This is where competitive differences show up: larger carriers usually have deeper dispatch benches and more rebooking options, while smaller carriers have fewer spares and fewer daily frequencies.
It’s also worth remembering that system constraints compound these events. If FAA staffing or traffic management initiatives hit at the same time, GDP-style delays can stack onto reroutes. That dynamic has been evident in GDP delays.
Mileage and points angle:
- You generally still earn miles based on fare paid or distance flown, depending on the program.
- A reroute doesn’t usually increase your mileage credit on U.S. airlines; revenue-based programs don’t care.
- If a reroute causes a misconnect and a rebooking, you might land on a different fare class, which can change partner earning.
- Award tickets can become a win during disruption weeks because you can often rebook without fare differences if the airline issues a waiver.
If you’re aiming for elite status, the bigger risk is missed segments. A cancellation can cost you a segment run and burn a vacation day.
6) Key facts and quick reference
NOTAMs are the authoritative channel during these events. They can change quickly, even inside the 60-day window. Treat the headline caution as the “why,” and the daily NOTAM feed as the “what now.”
A simple workflow that works for airlines and corporate travel teams:
- Assign one person per shift to check updates and flag material changes.
- Push a single daily summary to crews and schedulers.
- Document route decisions, fuel changes, and any navigation anomalies.
- File safety reports consistently, even when the flight ends normally.
For travelers, the smart move is also simple. If you’re flying through the eastern Pacific corridor before March 17, 2026, build connection buffer and pick routings with later backup flights.
If your schedule is tight, book earlier departures the same day so a reroute doesn’t turn into an overnight delay.
FAA Issues 60-Day Flight Caution for Pacific and Latin America Routes
The FAA issued a 60-day flight caution for the eastern Pacific and Latin American corridors, citing military activity and GPS interference risks. Running through March 17, 2026, the advisory impacts flights between the U.S., Mexico, and Central America. Airlines are adjusting flight plans, adding fuel, and monitoring navigation anomalies. Travelers should prepare for reroutes, longer flight durations, and potential missed connections during this period of heightened regional security.
