Airlines can no longer refuel on island as US blockade deepens energy crisis: Cuba

The Cuban Corporation of Aviation S.A. (CACSA) issued an urgent advisory to international airlines this week, notifying carriers that they can no longer provide aircraft refueling services at the island’s airports due to a deepening national energy crisis. This critical shortage of aviation fuel primarily affects major hubs like Havana’s Jose Marti International Airport, forcing foreign companies to adjust their flight paths or carry extra fuel burdens for return trips. The Cuban government attributes this sudden depletion of reserves to the tightening of the long-standing United States economic blockade, which has severely restricted the island's ability to import petroleum products and secure international financing for energy supplies. This logistics crisis marks a significant escalation in Cuba's broader energy instability, which has already resulted in widespread power outages and a near-total collapse of the national electrical grid in recent months. Aviation authorities confirmed that while domestic operations and emergency flights would be prioritized, international commercial carriers must now secure their own fuel strategy before arriving on Cuban soil. This development places an immense financial and technical burden on airlines, as carrying the weight of return-trip fuel—a practice known as 'tankering'—significantly increases operational costs and reduces the number of passengers or cargo an aircraft can safely carry. Diplomatic officials in Havana have repeatedly denounced the U.S. sanctions, arguing that the designation of Cuba as a state sponsor of terrorism has frightened off global shipping companies and oil suppliers. Without reliable access to tankers or the credit lines required to purchase fuel on the open market, the island’s infrastructure is failing at every level. Industry analysts suggest that if the refueling ban persists, several European and Latin American airlines may be forced to scale back their flight frequencies to the island, further isolating Cuba’s struggling tourism sector and damaging its primary source of foreign currency.
