Today, 507 flight cancellations and delays were recorded in Mexico, the Caribbean, and Puerto Rico, reflecting widespread disruption primarily related to U.S.-related air traffic. Of these, 246 cancellations were related to U.S.-related flights, highlighting the scale of the impact on the U.S. travel network.
The surge in cancellations coincides with a major winter weather system across the United States, with snow, sleet and freezing rain impacting travel conditions across a wide corridor from the southern Rockies to the Northeast, disrupting flights for more than half of the U.S. population.

The most affected airports include Cancun International Airport (89 cancellations, 76 delays), Luis Muñoz Marín International Airport, San Juan Airport (86 cancellations, 48 delays), Punta Cana International Airport (40 cancellations, 51 delays), and Licante International Airport (40 cancellations, 51 delays). Mexico City’s Benito Juárez International Airport (34 cancellations, 53 delays) and Santiago’s Cibao International Airport (30 cancellations, 0 delays).

Severe winter weather across the United States was the primary cause of US-related cancellations. 246 cancellations were related to flights within, to, or from the United States, with Cancun and San Juan having the highest number of combined cancellations. The airlines most affected by volume were JetBlue, American Airlines, and United Airlines. Some airports are experiencing non-delay cancellations, indicating that all flights are suspended.
