UK Faces Summer Flight Disruption Risk Amid Jet Fuel Warning

Britain has been named the most vulnerable country in Europe to potential jet fuel shortages this summer, after Ryanair chief executive Michael O'Leary issued a serious warning over the impact of the ongoing Iran conflict on global aviation fuel supplies.

O'Leary pointed to the UK's significant dependence on Kuwait — which accounts for roughly a quarter of Britain's jet fuel supply — as the key reason for the country's heightened exposure. With that fuel transported by tanker through the Strait of Hormuz, a shipping corridor that Iran has been restricting, the ability to maintain a steady flow of aviation fuel into the UK is now genuinely in question.

Speaking to Sky News this week, O'Leary said fuel companies do not expect disruption before early May, but warned that if the conflict continues, Europe could face supply shortfalls through May and June. He estimated that between 10 and 25 per cent of Ryanair's fuel supply could be at risk during that period, a level that could force airlines to reduce capacity or pull certain routes entirely.

For British holidaymakers, the timing could not be more concerning. The peak summer travel season — when demand for flights is at its highest — falls squarely within the window of greatest risk. Several international carriers have already adjusted their schedules in response to rising costs and uncertainty, and airlines operating out of UK airports are reviewing their networks on a weekly basis.

Jet fuel prices have also nearly doubled in recent weeks, placing significant financial strain on carriers. While major airlines, including Ryanair, have hedged a large portion of their fuel costs through pre-agreed contracts, the unhedged remainder is now being purchased at close to market highs. Industry experts warn this will eventually be reflected in ticket prices, with passengers on unbooked or future flights likely to see fares increase as the summer approaches.​​​​​​​
