European holidaymakers are being warned to brace for potential travel chaos as fears grow over a jet fuel shortage that could hit within six weeks. The crisis, linked to disruption caused by the war involving Iran and instability in key oil transit routes, has already driven jet fuel prices to double, leading to higher air fares and raising the prospect of cancelled flights during the peak summer season.

The head of the International Energy Agency cautioned that Europe may have only weeks of jet fuel supplies left if conditions do not improve, warning that flights between major cities could soon be cancelled. European airport leaders have expressed increasing concern, particularly for smaller airports that may be more vulnerable to supply disruptions. British officials are preparing contingency plans, with expectations that a limited percentage of flights may need to be cancelled if shortages materialise.

At the same time, new border control systems introduced across Europe are causing long queues and delays, with warnings that families could face waits of up to four hours at some airports during the busy holiday period. Industry figures have urged authorities to ensure adequate staffing and functioning technology to prevent further disruption.

In worst case planning scenarios, emergency aircraft such as air ambulances and police helicopters would be prioritised for fuel. Travel experts advise passengers to consider package holidays for greater financial protection, as airlines and governments continue discussions on how to manage the potential impact on travellers.
