Long-Haul Flight Fares Soar as Iran War Hits European Aviation Hard

The Sky-High Cost of Fuel Dependency: What the Jet Fuel Crunch Means for the Future of Flight

The aviation industry is currently facing a moment of reckoning. A combination of geopolitical instability in the Middle East and a fragile supply chain has sent shockwaves through European skies, manifesting most visibly in the wallets of travelers.

Recent analysis shows that long-haul flights from Europe have seen an estimated price increase of $105 (€90) per ticket since the outbreak of the war. Even as short-haul routes are similarly feeling the pinch, the volatility of long-distance travel highlights a systemic vulnerability: an over-reliance on fossil fuels and specific geopolitical corridors.

The Strait of Hormuz: A Single Point of Failure

The current crisis has exposed how easily global aviation can be shaken by conflict. A primary bottleneck is the Strait of Hormuz, a key gateway for energy flows from the Gulf. According to IATA, tanker traffic through this strait has collapsed by 70-80%, rendering it effectively impassable.

This is catastrophic for Europe because roughly 30% of its jet fuel supply—including both crude oil refined within the EU and directly imported refined fuel—relies on imports via the Strait of Hormuz. With the IEA warning that Europe may have only about six weeks of remaining jet fuel supply, the industry is staring down the barrel of potential flight cuts.

The “Asian Shift” and Supply Competition

The problem is compounded by global competition. As Asian countries limit their own jet-fuel exports to secure their domestic supplies, Europe is finding itself in a bidding war. Market analysts suggest that U.S. Jet fuel cargoes, which might have previously headed to Europe, are increasingly being diverted to Asia, further tightening the squeeze on Northwest Europe.

The Strategic Pivot: Diversification and Self-Sufficiency

In response to these vulnerabilities, the European Union is drafting new guidelines to urge member states to slash their dependence on Middle Eastern jet fuel. The strategy is twofold: seeking increased imports from the U.S. And accelerating the transition to homegrown energy solutions.

A critical component of this future trend is the scaling of Sustainable Aviation Fuel (SAF) and synthetic fuels. By shifting toward self-sufficiency and resilience, the EU aims to decouple air travel from the volatility of oil-producing regions.

Climate Regulation as a Tool for Energy Security

There is an ongoing debate within the industry regarding climate legislation. Some players have used geopolitical instability to lobby against regulations like the Emissions Trading System (ETS) and ReFuelEU. But, the climate campaign group Transport & Environment (T&E) argues the opposite.

T&E asserts that these climate laws are actually essential blueprints for achieving energy independence. By forcing a transition away from fossil fuels, these regulations reduce the sector’s exposure to global oil shocks. In this light, the “green transition” is not just about the environment—it is a matter of national and economic security.
