Cuban aviation officials have warned airlines of a fuel shortage for refueling on the island. This is part of energy rationing as the Trump administration cuts Cuba off from its fuel sources. A commercial pilot confirmed the notice was sent Sunday. The shortage stems from U.S. political pressure severing Cuba’s access to oil from Venezuela and Mexico. Shorter flights may not be affected, but long-haul routes face challenges. The energy crisis has led to reduced bank hours, suspended cultural events and halted public transport. U.S. sanctions have long impacted Cuba, but recent measures have intensified the situation.
