A significant jet fuel shortage in Europe and Asia, caused by the Iran war and the closure of the Strait of Hormuz, threatens to disrupt global travel soon. The International Energy Agency warns that Europe has only about six weeks of jet fuel left, leading to potential flight cancellations and increased airfares. Airlines are already raising fees and cutting flights due to surging fuel costs. The situation is expected to worsen, particularly affecting regions reliant on Middle Eastern oil, with experts predicting a long recovery period.
