• Global jet fuel shortages are driving up costs and threatening flight disruptions, particularly during the Northern Hemisphere summer peak.
  • The impact is expected to hit Asia first, then spread to Europe, Africa, and Latin America, with potential fuel rationing leading to cancellations.
  • Airlines are likely to pass higher costs to passengers through increased fares, as absorbing the surge is not feasible.

Rising Costs and Supply Squeeze

The global jet fuel market is tightening amid geopolitical shocks and refinery constraints, raising the specter of higher airfares and flight cancellations during the peak summer travel season. Willie Walsh, director general of the International Air Transport Association (IATA), described the situation as serious but far less severe than the COVID-19 pandemic, noting that air travel demand remains robust. However, the main risk lies in potential fuel shortages, which could trigger rationing in Asia and Europe, leading to some flight cancellations.

According to people familiar with the matter, the crisis is expected to first manifest in Asia due to its reliance on Middle Eastern crude and limited refinery capacity, before spreading to Europe, Africa, and Latin America. Refinery outages and disruptions in the Strait of Hormuz have exacerbated the supply crunch, leaving jet fuel inventories at multi-year lows in several regions.

Airlines Brace for Impact

Airlines are already feeling the pinch. Carriers including Delta, United, and Alaska Air have reported higher fuel bills and are adjusting operations. "We cannot absorb these cost increases," a senior executive at a major European airline said on condition of anonymity. "Without a deal to secure supply, we would be forced to cut flights." Walsh echoed this sentiment, warning that airlines would need to raise fares to offset the rising costs.

The pressure is particularly acute for low-cost carriers operating on thin margins. Analysts at industry consultancy said that fuel now accounts for over 40% of operating expenses for some airlines, up from 30% earlier this year. This could lead to schedule reductions, particularly on less profitable routes.

Regional Variations and Outlook

The impact is uneven across regions. In Asia, spot jet fuel prices have surged to multi-month highs, with some airports reporting supply delays. In Europe, major hubs are bracing for potential rationing as refineries struggle to meet demand. Africa and Latin America, which rely heavily on imports, may face the most severe disruptions.

Walsh emphasized that the industry is better prepared than during the pandemic, but the current crisis is testing resilience. "We are in close contact with governments to ensure fuel supply chains remain open," he said. The path to normalization could take months, depending on geopolitical developments and refinery restarts.

For now, passengers can expect higher fares and potential last-minute changes, especially during peak travel windows. Airlines are urging travelers to book early and remain flexible.

Correction: An earlier version of this article misstated the timing of the fuel crisis. The impact is expected in the Northern Hemisphere summer peak of 2026, not 2025.

Industry Response and Next Steps

IATA is coordinating with regional regulators to monitor supply and explore contingency measures, including strategic fuel reserves. Some airlines are accelerating fleet modernization to improve fuel efficiency, but near-term capacity adjustments appear unavoidable.

As the situation evolves, the industry is watching key geopolitical developments, particularly in the Middle East, for signs of easing. Until then, the jet fuel crunch will continue to reshape travel costs and schedules worldwide.
