More than 300 flights were canceled when air travel to Puerto Rico was suspended

Commercial air travel to and from Puerto Rico was disrupted on Saturday, January 3, after federal authorities temporarily banned US airline operations at several Caribbean airports, citing security concerns related to increased military activity in Venezuela.

The pause includes Luis Muñoz Marín International Airport (SJU), the Caribbean’s busiest hub, as well as airports in Ceiba, Aguadilla, Ponce, Isla Grande, Vics and Culebra, according to Norberto Negron Diaz, executive director of the Puerto Rico Ports Authority.

Acting under orders from the Federal Aviation Administration, commercial passenger and cargo operations were suspended until 1 a.m. Sunday, January 4, with the possibility of an extension.

How many flights have been canceled from Puerto Rico?

According to flight-tracking website FlightAware, more than 300 departing and arriving flights have been canceled by midday on January 3.

Aerostar Airport Holdings, which manages SJU, said the temporary airspace restriction arises because of “the security situation related to military activity in Venezuela.” The operator warned that most flights operated by US airlines to and from San Juan were suspended or subject to cancellation, while flights by foreign airlines and military aircraft were not affected. The company urged passengers to check flight status directly with their airlines before heading to the airport.

Puerto Rico Governor Jennifer Gonzalez described the shutdown as a national security measure during a radio interview, as reported by local news outlet El Nuevo Día. He said that local bodies are coordinating with federal partners for airport and cargo operations.
