Jet fuel prices have doubled since conflict erupted in the Middle East, and the global aviation industry is bracing for what could be the first worldwide fuel shortage in commercial air travel history. The strait of Hormuz, through which 41% of European aviation fuel passes, has become a bottleneck that is already reshaping airline schedules and traveler behavior.
The crisis is not yet catastrophic on the supply side. While global jet fuel shipments fell to record lows last week at 2.3 million tonnes, crude oil production still exceeds global demand. About 15 million barrels of oil daily normally flow through Hormuz, but alternative routes via pipeline and coastal ports can absorb some of that volume. Refineries also have limited flexibility to adjust fuel ratios from raw crude, though that margin is finite.
Price, however, is another matter. If the conflict persists until late June, energy analysts warn that fuel buffers will evaporate entirely, leaving the market vulnerable to explosive price spikes. Aviation fuel is already roughly equivalent to what gasoline cost at pumps last year, and the damage is visible across the industry.
Lufthansa cut 20,000 flights in April. Spirit Airlines declared bankruptcy. Virgin announced it cannot absorb higher fuel costs and will raise fares. British Airways parent IAG acknowledged it is making pricing adjustments. EasyJet launched a "book with confidence" guarantee protecting customers from post-purchase price hikes, a sign of extraordinary market turbulence. The airline hedged 70% of its fuel needs until September, locking in costs when others face open exposure.
Among travelers, the response has been swift and cautious. A poll of travel executives conducted in March found 49% expected week-to-week price fluctuations. Passengers are delaying bookings, waiting for clarity. Word-of-mouth advice circulates: book flights to the largest regional airport you can reach, because small routes will be cut first. This rumor-driven booking behavior marks uncharted territory for the industry.
Airlines with fuel hedging strategies are navigating the crisis more smoothly than those exposed to spot prices. Lufthansa locked in 80% of its fuel costs for the year, giving it stability. Ryanair claims to be Europe's most hedged carrier. But low-cost carriers with short-haul networks face the greatest exposure, and if they collapse, stranded passengers at distant destinations have few options to return home affordably.
The geopolitical dimension makes this crisis uniquely systemic. The Middle East controls not just oil reserves but aviation infrastructure and energy routing. Unlike the early stages of the Ukraine war, which created uncertainty, this disruption affects pricing, supply, and confidence simultaneously across the globe.
The silver lining, if one exists, could accelerate the transition away from fossil fuels in aviation. Jet zero technologies exist but remain prohibitively expensive. Synthetic fuel, which rebuilds hydrocarbons from captured carbon and hydrogen, costs roughly 10 times more than kerosene and requires enormous renewable energy inputs. Hydrogen-powered engines work in principle, as Rolls-Royce demonstrated, but require cryogenic treatment and would demand rebuilding a century of aviation infrastructure designed for liquid kerosene.
The deeper obstacle is economic incentive. Jet fuel escapes taxation under a 1944 Chicago Convention that determined flying was not a national activity, making kerosene effectively subsidized. This advantage makes alternatives uncompetitive. Yet engineers believe that before the end of this century, post-fossil-fuel aviation will operate at scale if crisis forces the transition early enough.
One certainty: flying may become a more exclusive activity than it already is. Half of Britons take fewer than one flight annually, and 80% of humans have never flown. For them, fuel shortages are an abstraction. For others, higher prices mean fewer trips, regional travel instead of long-haul, or staying home. The damage extends beyond wealthy passengers, though. African agricultural regions dependent on fertilizer imports from the Gulf face serious planting disruptions.
The oil industry has a saying, attributed to a legendary OPEC figure: the stone age did not end because humans ran out of stones, and the oil age will end long before the world exhausts its reserves. A crisis may be the only catalyst powerful enough to accelerate that end.
Author James Rodriguez: "The airline industry built its entire business model assuming cheap fuel would always flow; now it's learning what happens when that assumption breaks."
