Europe is rapidly approaching a critical jet fuel shortage, with inventories expected to dip below the International Energy Agency’s 23-day threshold in June. This development could trigger widespread flight cancellations and the potential closure of smaller airports, amplifying travel disruptions across the continent.

Mounting Risks for Air Travel

The U.K. is particularly at risk due to its reliance on fuel imports, according to a Goldman Sachs report. While the threshold does not indicate an immediate depletion of supplies, it underscores the tightening global crude and fuel markets exacerbated by the ongoing closure of the Strait of Hormuz amid escalating tensions in Iran.

'We’re still kind of sleepwalking into this approaching disaster. There is little doubt there is going to be a disaster,' said Claudio Galimberti, chief economist at Rystad Energy.

European refineries have increased jet fuel production, but this marginal adjustment may not suffice as inventories at the Amsterdam-Rotterdam-Antwerp benchmark have plummeted by 50% since February. Southern Europe, heavily dependent on Middle Eastern petroleum imports, is also highly vulnerable to disruptions.

Travel Impacts and Industry Response

Already, tens of thousands of flights have been canceled for the summer, with Lufthansa alone axing 20,000 flights through October. Airfare prices have surged by at least 20% compared to last year, further straining travelers. Experts advise booking nonstop flights from major airports and securing travel insurance to mitigate potential disruptions.

Refineries across Europe are prioritizing jet fuel production, with TotalEnergies CEO Patrick Pouyanné emphasizing a 'max jet first' strategy. However, this shift will only marginally increase output, from roughly 10% to 13%, leaving airlines grappling with insufficient supplies.

The situation highlights the fragile nature of global energy markets and the far-reaching consequences of geopolitical instability. With no end in sight to the Strait of Hormuz closure, travelers and the aviation industry face an uncertain summer.
