Air Canada has announced the immediate suspension of all flights to Cuba due to a severe shortage of jet fuel on the island, exacerbated by the ongoing U.S. oil blockade. The situation has led to Cuba implementing emergency measures to conserve fuel while its airports warn of an inability to refuel international airlines. This crisis impacts numerous travelers, with some Canadian tourists stranded while airlines like WestJet and Air Transat navigate the evolving circumstances. As Cuba faces rolling blackouts and food shortages, the international community is raising alarms about potential humanitarian consequences stemming from these fuel shortages and the accompanying U.S. sanctions.
