The Cuban government has issued a warning to international airlines operating in the country that it will run out of aviation fuel beginning February 9, exacerbated by ongoing U.S. sanctions against its oil supply. Airlines mainly affected include those from the United States, Spain, Panama, and Mexico, which have not yet publicly detailed their plans to manage this situation. This shortage could lead to disruptions in flight schedules and routes, particularly in the short term. Historically, during similar crises in the 1990s and more recent temporary shortages, airlines have adapted by modifying their routes to include additional stops for refueling in locations such as Mexico or the Dominican Republic. As the majority of flights from Cuba connect to destinations in Florida, Spain, and Panama, the implications of this fuel shortage could significantly impact air travel, leading to potential increases in fares and longer travel times as airlines seek alternative solutions to keep operations running amidst these heightened restrictions and dwindling resources.
