Iran Conflict Disrupts Jet Fuel Supply, European Airlines Scale Back Summer Schedules

Europe’s aviation sector is facing a potential crisis as a growing jet fuel shortage threatens to disrupt summer travel schedules. The situation has been triggered by the ongoing conflict involving Iran and the effective closure of the Strait of Hormuz, a key route for global fuel shipments. As supplies from the Middle East are choked off, the impact is being felt most strongly across European airlines and airports.

Several major carriers have already begun cutting back operations. Lufthansa announced it will cancel around 20,000 flights through October, reducing its daily schedule by roughly 120 flights across major hubs such as Frankfurt, Munich, Zurich, Vienna, Brussels, and Rome. Meanwhile, Norse Atlantic Airways has reduced long-haul services, including routes from Los Angeles, and Delta Air Lines has trimmed its expected capacity by 3.5% due to rising fuel costs.

Europe’s heavy reliance on imported jet fuel has made it particularly vulnerable. The region consumes approximately 1.6 million barrels per day, with about one-third imported. Of those imports, roughly 75%—around 375,000 barrels daily—traditionally come from the Middle East. With these supplies now severely disrupted, the market is under strain, and fuel prices in Europe have already doubled since the conflict began.

Fuel reserves are also declining rapidly. The International Energy Agency estimates that Europe may have only six weeks of jet fuel supply remaining. Analysts warn the situation could deteriorate even faster, as previously scheduled shipments have now largely stopped. Experts suggest that available inventories could be exhausted within four to five weeks if no new supply routes are secured.

Efforts are underway to find alternative sources, including increased imports from Africa and the United States. US exports of jet fuel have nearly doubled to around 400,000 barrels per day, but much of this supply is already allocated to nearby markets, limiting its availability for Europe. Unusual shipping patterns, such as tankers traveling from New York to Europe, underscore the severity of the shortage.

For travelers, the consequences are likely to include higher ticket prices and potential disruptions, particularly on European routes. While passengers in other regions may not face immediate shortages, rising fuel costs are expected to affect global airfare. Ongoing uncertainty about fuel availability—especially for return flights—could make travel to Europe less predictable during the busy summer season.
