Puerto Rico’s Luis Munoz Marin International Airport in San Juan suspended most commercial flights operated by U.S. airlines on Saturday after the Federal Aviation Administration imposed a temporary airspace restriction, airport operator Aerostar Airport Holdings said. Aerostar said the order has an initial 24-hour window and could be extended, and it does not apply to foreign airlines or military aircraft; the operator did not specify how many flights were affected. San Juan is Puerto Rico’s main aviation gateway, and the suspension threatens to snarl travel as airlines push winter capacity into the Caribbean. The move also underscores how quickly security steps tied to Venezuela can spill into civilian air traffic in U.S. territory.

Australian wagyu and Angus beef exporters are bracing for a squeeze in China as a new quota-and-tariff system pushes buyers and sellers into a race for limited “in-quota” access. Producers say the change risks sidelining higher-value chilled beef if bigger processors rush lower-priced product into China early in the year.
