Airlines Cut Flights as Iran War Drives Jet Fuel Squeeze

Air travelers are facing fresh disruption as airlines around the world cancel flights, trim schedules and raise prices in response to jet fuel shortages and a rapid surge in fuel costs linked to the Iran war.

Conflict in Iran Ripples Through Global Fuel Supply

The outbreak of war involving Iran in late February has quickly evolved into a shock to global energy markets, with oil and gas flows from the Gulf region disrupted by attacks on fields, refineries and export infrastructure. The Strait of Hormuz, a critical chokepoint for seaborne crude and refined products, has seen repeated interruptions to tanker traffic, reducing the availability of jet fuel in key hubs.

Market data compiled in recent weeks shows Brent crude prices climbing sharply after strikes on Iran’s South Pars gas field and other facilities, while parallel attacks and security incidents in Saudi Arabia and Qatar have further unsettled supply. Analysts note that roughly one fifth of the world’s oil and gas usually moves through the Strait of Hormuz, and even partial closures are enough to tighten global inventories and send prices higher.

Jet fuel has been particularly affected. Industry trackers report wholesale jet fuel benchmarks rising far faster than crude, with some assessments indicating gains of 60 to 90 percent compared with prewar levels. The result is a steep and sudden increase in airlines’ single largest variable cost at the very moment carriers had been counting on a busy 2026 travel season.

According to publicly available analysis from energy consultancies and aviation data providers, the price surge has pushed average jet fuel costs in some regions to their highest point since the post‑pandemic energy crunch in 2022, though this spike has arrived much faster and with less warning.

Airlines Cancel Flights and Trim Schedules

As fuel bills climb and physical supplies tighten, airlines are beginning to cut flying rather than absorb the full financial hit. In Europe, published coverage indicates that Scandinavian carrier SAS has withdrawn more than a thousand flights from its schedule between mid March and early May, citing unaffordable fuel costs on certain routes. The cancellations are affecting tens of thousands of passengers across Nordic and intra European networks.

In Asia, the squeeze is even more acute. Regional reporting shows that jet fuel prices in parts of Asia and Oceania have more than doubled compared with early 2026, after Iran’s closure of the Strait of Hormuz forced refiners and traders to scramble for alternative supplies. Airlines in Vietnam, Thailand, Sri Lanka and Myanmar have responded by grounding selected domestic and regional services, leaving travelers with fewer options and, in some cases, last minute cancellations.

Major global network carriers are also paring back growth plans. Industry briefings reviewed by TheTraveler.org indicate that at least one large North American airline has announced capacity reductions of around 5 percent for upcoming quarters, with cuts focused on off peak frequencies and energy intensive long haul routes to the Middle East. Similar, though smaller, adjustments are being reported at carriers in Africa and Latin America, where thinner profit margins make it harder to absorb sudden fuel spikes.

For passengers, the immediate impact is a combination of fewer available seats and growing uncertainty around route stability, especially on flights touching the Gulf region or relying on smaller regional airports where fuel deliveries have become less predictable.

Jet Fuel Shortages Hit Regional Hubs

Beyond the financial strain, the conflict is also creating localized shortages of aviation fuel that are forcing airlines to rethink how and where they operate. Civil aviation authorities in Southeast Asia have warned that supplies of Jet A 1 fuel at some airports are constrained, particularly where stocks had been heavily reliant on shipments routed through the Gulf.

Reports from airline operations teams suggest that carriers are increasingly using “tankering” strategies, loading extra fuel at larger hubs where supply is more secure in order to avoid refueling at outstations facing shortages. While this allows flights to continue, it adds weight and further increases fuel consumption, compounding cost pressures.

In Africa, local media have described a severe squeeze on jet fuel for domestic and regional airlines after import prices rose more than 70 percent since the start of the war. Some low cost carriers are said to be evaluating whether to suspend marginal routes or reduce weekly frequencies, because the extra cost per flight hour has eroded already thin margins.

Industry analysts caution that if disruptions in the Strait of Hormuz persist into the peak northern summer season, more airports could see intermittent or rationed fuel deliveries. That scenario would likely trigger further schedule changes and encourage airlines to prioritize aircraft and fuel for their highest yielding routes.

Rising Fares, Surcharges and New Fees for Travelers

With jet fuel accounting for a growing share of operating expenses, airlines are moving quickly to pass some of the burden to passengers. Several carriers in Asia and the Pacific have introduced fuel surcharges of between 10 and more than 30 percent on new ticket sales, explicitly linking the new fees to the jump in fuel prices following the Iran conflict.

In North America and Europe, major airlines are raising ancillary charges and adjusting fare structures. Publicly available announcements from large United States carriers show increases in checked baggage fees that executives have connected to higher fuel costs, alongside new or expanded premium fare tiers designed to capture more revenue from travelers willing to pay for flexibility and comfort.

European airline groups have publicly warned that sustained fuel price pressure will translate into higher base fares over the coming months, urging travelers to book early to secure lower prices. Budget and leisure focused operators, which typically have less fuel hedging in place than legacy airlines, are seen as particularly exposed to further increases in jet fuel benchmarks.

Travel industry analysts say the combination of schedule cuts and rising surcharges is already visible in fare data on select long haul markets, especially routes touching the Middle East and Asia. If energy prices remain elevated through the summer, the expectation is for broader fare increases across transatlantic and intra European networks as well.

What Travelers Should Expect in the Months Ahead

With the Iran war still unfolding and energy markets on edge, aviation forecasters describe the current environment as highly uncertain. While some governments are exploring measures such as temporary waivers of shipping rules or strategic fuel releases to ease supply bottlenecks, the underlying disruption to Gulf oil and gas flows remains unresolved.

Most publicly available outlooks from airline trade groups and consultancies suggest that travelers should be prepared for a period of volatile pricing, sporadic schedule changes and tighter capacity on certain routes. Long haul itineraries that rely on connections through Middle Eastern or Southeast Asian hubs are considered most vulnerable to additional disruption if fuel shortages worsen.

For now, booking trends indicate that demand for international travel remains resilient despite higher prices, but confidence could erode if cancellations mount or if the conflict in Iran broadens further. The next few months will test airlines’ ability to balance financial discipline with the need to maintain connectivity in an increasingly constrained fuel market.

As jet fuel costs continue to rise and supplies remain tight, the global aviation system is likely to feel the effects well beyond the immediate war zone, reshaping flight networks and altering the cost of air travel for millions of passengers worldwide.
