Over 300 Flights Canceled as Puerto Rico Air Travel Is Temporarily Suspended

More than 300 flights to and from Puerto Rico were canceled Saturday, Jan. 3, after federal authorities temporarily restricted U.S. airline operations at multiple airports across the region. Officials cited security concerns tied to escalating military activity in Venezuela as the reason for the sudden disruption.

The restrictions hit Puerto Rico especially hard because they included Luis Muñoz Marín International Airport (SJU) in San Juan, the busiest airport hub in the Caribbean. Additional airports affected included Ceiba, Aguadilla, Ponce, Isla Grande, Vieques, and Culebra, according to Puerto Rico Ports Authority Executive Director Norberto Negrón Díaz.

Federal officials acted through orders from the Federal Aviation Administration. Under that directive, commercial passenger and cargo flights were suspended through 1 a.m. Sunday, Jan. 4, with the possibility that the shutdown could be extended depending on how the situation develops.

Why Flights Were Restricted

Airport operator Aerostar Airport Holdings, which manages Luis Muñoz Marín International, said the temporary airspace restriction stemmed from what it described as “a security situation related to military activity in Venezuela.” The company warned travelers that most flights operated by U.S. airlines to and from San Juan were either suspended outright or likely to be canceled.

Aerostar also noted an important detail for travelers watching the boards: the disruption primarily affected U.S. airline flights. Foreign carriers and military aircraft were not impacted by the restriction in the same way, meaning some air traffic could still move even while commercial U.S. flights remained paused.

Because conditions were changing quickly, Aerostar urged travelers not to assume their flight would operate normally and to confirm their status directly with their airline before heading to the airport.

How Many Flights Were Canceled?

As of midday Saturday, flight-tracking website FlightAware showed that over 300 flights arriving to and departing from Puerto Rico had been canceled. That number reflected widespread disruption across the island’s airports, with ripple effects likely for connections throughout the Caribbean and the U.S. mainland.

Even travelers who weren’t flying into San Juan could feel the impact, since cancellations at the region’s largest hub can create aircraft and crew shortages that knock schedules out of alignment for days.

Puerto Rico Officials Call It a National Security Measure

Puerto Rico Gov. Jenniffer González described the closure as a national security action during a radio interview, according to local outlet El Nuevo Día. She said local agencies were working alongside federal partners to keep airport operations coordinated, especially when it came to managing cargo activity and the operational flow at impacted facilities.

For travelers on the ground, that coordination matters because it can affect everything from rebooking support to how quickly airports reopen once restrictions lift.

Airline Travel Waivers and Flexible Rebooking Options

With flights halted and cancellations stacking up, several major U.S. airlines issued travel waivers that allow customers to change plans without the usual penalties. While each carrier’s policy varies, the goal is the same: help passengers rebook quickly, avoid change fees, and in many cases receive refunds when flights are canceled.

Here’s a breakdown of the major waivers announced for Puerto Rico and other impacted Caribbean destinations.

American Airlines

American waived change fees for customers who booked by Jan. 2 and were scheduled to travel Jan. 3 to Jan. 4, 2026. The waiver applied to several affected destinations, including San Juan (SJU), Aruba (AUA), Antigua (ANU), St. Thomas (STT), St. Maarten (SXM), and others. Travelers could rebook through Jan. 9 as long as the origin and destination stayed the same, and the ticket needed to be reissued by Jan. 4.

JetBlue

JetBlue offered fee-free changes or cancellations for customers traveling Jan. 3 to Jan. 4 to or from impacted airports such as San Juan (SJU), Aguadilla (BQN), Ponce (PSE), Aruba (AUA), Curaçao (CUR), and St. Lucia (UVF). Rebooking was allowed through Jan. 10. JetBlue also said refunds would be available for canceled flights, provided the trip was booked before Jan. 3.

Southwest Airlines

Southwest warned that flights scheduled for Saturday, Jan. 3 to Aruba (AUA), Punta Cana (PUJ), and San Juan (SJU) could be disrupted. The airline allowed customers to rebook or fly standby within 14 days without paying a fare difference. Southwest also noted that refunds may apply for flights that were canceled or significantly delayed.

United Airlines

United waived change fees and fare differences for eligible tickets purchased by Jan. 2 with travel scheduled Jan. 4 to Jan. 6, 2026. The waiver covered destinations including San Juan (SJU), Antigua (ANU), Aruba (AUA), and St. Thomas (STT). New travel needed to depart between Jan. 6 and Jan. 13.

Frontier Airlines

Frontier waived change and cancellation fees for flights scheduled Jan. 3 to Jan. 4 to or from San Juan (SJU), Ponce (PSE), Aguadilla (BQN), Aruba (AUA), and St. Maarten (SXM). Frontier noted that while fees were waived, fare differences could still apply, and canceled trips would convert into travel credit.

Spirit Airlines

Spirit waived modification charges and fare differences for flights Jan. 3 to Jan. 4 to or from San Juan (SJU), Aruba (AUA), St. Croix (STX), St. Thomas (STT), and St. Maarten (SXM). The airline allowed rebooking through Jan. 11.

What Travelers Should Do Right Now

If you’re traveling to or from Puerto Rico or connecting through the Caribbean, airlines are strongly encouraging passengers to monitor their flight status closely. The safest approach is to manage changes directly through your carrier’s app or website, since airport ticket counters can get overwhelmed quickly during large-scale disruptions.

Until the FAA restriction fully lifts and normal schedules resume, travelers should expect delays, cancellations, and rebooking challenges to continue, even after flights begin operating again.
