Sky-High: How the Iran Conflict Turned Spring Travel Into a Fuel-Price Nightmare

Just weeks ago, travelers were locking in what looked like bargain spring break fares. Priceline's annual snapshot showed domestic roundtrip tickets averaging $340 — down 7% year over year — and international fares averaging $703, an 8% decline [1]. Airlines were forecasting a "record-breaking" spring travel season, with 171 million passengers expected to fly between March and April [2].

Then, on February 28, the United States and Israel launched military strikes on Iran. Within days, the Strait of Hormuz — the narrow waterway through which roughly one-fifth of the world's oil supply transits — was effectively closed [3]. Oil prices spiked above $100 per barrel. Jet fuel costs, which sat at $85–$90 per barrel before the strikes, soared toward $150–$200 [4]. And the sticker shock on spring airfares became very real.

The Oil Shock That Changed Everything

The Strait of Hormuz crisis represents the most severe disruption to global energy markets in decades. Approximately 13 million barrels of crude per day flowed through the strait in 2025, representing about 31% of all seaborne crude flows [5]. When Iran's Islamic Revolutionary Guard Corps declared that "not a litre of oil" would pass through, the consequences rippled instantly through commodity markets [3].

West Texas Intermediate crude, which had been trading in the $57–$67 range since November 2025, rocketed from $66.96 on February 27 to $94.65 by March 9 — a 41% surge in less than two weeks [6]. Brent crude briefly touched $119 per barrel before settling near $100 [7]. Iran's IRGC spokesperson warned traders to expect $200 oil, while research firm Wood Mackenzie predicted prices could reach $150 in the coming weeks [3].

The shock was amplified by production cuts across Gulf states. Saudi Arabia, Iraq, the UAE, Kuwait, Qatar, Bahrain, and Iran — all of which depend on the strait for exports — collectively reduced output by an estimated 10 million barrels per day by March 10 [7].

From Barrel to Boarding Pass: How Fuel Costs Hit Your Ticket

Fuel typically accounts for about 25–27% of an airline's total operating expenses, according to the International Air Transport Association [8]. But with oil above $100, that share has surged toward 40% for some carriers [9]. The math is punishing: for every one-cent increase in the price of a gallon of jet fuel, a major carrier like Delta Air Lines faces roughly $40 million in additional annual costs [9].

At the start of 2026, a gallon of jet fuel cost $2.11. By March 10, the price had risen to $3.40 — an increase of more than 60% [4]. In Asia, jet fuel prices surged over 70%. In Europe, the increase topped 140%, partly because roughly 30% of Europe's jet fuel supply originates from or transits through the Strait of Hormuz [5][10].

The airline industry's vulnerability is compounded by a strategic decision most U.S. carriers made years ago: they stopped hedging fuel costs. United Airlines, American Airlines, Southwest Airlines, and others hold no forward contracts that lock in fuel prices [4]. Delta enjoys a partial hedge through its ownership of the Trainer refinery in Pennsylvania, which shields it from refining margins — but it still pays market rates for crude [9].

"This will have a meaningful effect," United Airlines CEO Scott Kirby said at a Harvard University event on March 11. "The impact on fares will probably start quick." [4]

The Fare Hikes Begin

International carriers moved first. Australia's Qantas Airways, Scandinavia's SAS, and Air New Zealand all announced fare increases directly tied to fuel costs [10]. Cathay Pacific said it would roughly double its fuel surcharges on tickets starting March 18 [4]. Air New Zealand added surcharges of NZ$10 on domestic flights, NZ$20 on short-haul international routes, and NZ$90 on long-haul flights [10]. Thai Airways announced plans to raise ticket prices by 10–15% [11].

Willie Walsh, director general of IATA, warned that the cost of plane tickets globally could jump as much as 9% [10]. But some analysts said that figure was conservative. Skift Research estimated that U.S. domestic flight prices would need to increase by at least 11% to offset current fuel costs [4]. On routes where airlines face the most acute fuel-cost exposure — particularly long-haul international flights through rerouted corridors avoiding Middle Eastern airspace — the increases are far steeper.

U.S. carriers quickly followed. By the second week of March, United, Delta, American, JetBlue, Southwest, Alaska, and Hawaiian airlines were all witnessing what one industry report described as a "skyrocketing surge" in fares on routes from the United States to major global destinations [12]. The increases were most dramatic on transpacific routes to Southeast Asia and Oceania, where Middle Eastern airspace closures forced costly detours.

Route Cancellations and Schedule Chaos

The cost pressure is not just raising prices — it is shrinking the map. Air New Zealand announced the cancellation of 1,100 flights, affecting more than 44,000 passengers, between March and early May [11]. United Airlines pulled a second daily summer flight between Newark and Brussels, as well as a planned second summer flight between Newark and Edinburgh [13].

The Federal Aviation Administration reported 303 flight cancellations on March 6 alone, a figure amplified by the convergence of fuel-cost pressure, Middle Eastern airspace rerouting, and the beginning of the spring break travel surge [14]. Airlines serving routes to Thailand, in particular, have been heavily affected by the closure of Middle Eastern airspace, triggering cascading delays and cancellations [11].

Lufthansa, already dealing with a full-day pilot walkout on February 12 that canceled hundreds of flights and disrupted travel for 100,000 passengers, faces the compounding challenge of Europe's acute jet fuel price surge [11].

Wall Street Takes Notice

Financial markets have rendered a harsh verdict. Airline stocks are among the worst-performing sectors since the strikes began. By March 12, United Airlines Holdings had cratered 33% in a single trading session [9]. American Airlines and JetBlue saw double-digit percentage drops. The broader airline sector fell roughly 30% year-to-date [15].

Delta Air Lines performed somewhat better than its peers, thanks to its Trainer refinery hedge, but it could not escape the sector-wide sell-off [9]. Analysts at 24/7 Wall Street warned that if oil sustained levels above $100, both Delta and United would face serious financial strain [16].

The market's alarm reflects a painful calculation. Airlines that cannot hedge fuel and cannot immediately pass all costs to consumers face margin compression at precisely the moment when demand — and thus revenue potential — should be at its seasonal peak.

Consumer Response: Traveling Smarter, Not Canceling

Despite the turbulence, Americans are not abandoning their travel plans — they are reshaping them. A RetailMeNot survey of more than 1,100 U.S. adults found that 61% still plan to travel this spring, up from 48% last year [1]. But the average planned spending per trip has dropped 11%, from $1,370 to $1,219 [1].

About a third of travelers said they are taking shorter trips — a long weekend instead of a full week. Another 26% are choosing more budget-friendly destinations. And 15% are stacking discounts, rewards points, and cash-back offers to offset higher costs [1]. Thirty-six percent of spring travelers reported using AI tools to compare prices, research destinations, and time their bookings [1].

Travel experts are offering urgent advice: book now. "If you're planning to fly this summer, lock in your airfare today," recommended The Points Guy, noting that tickets purchased two weeks from now are likely to cost more than those bought today [17]. CNBC's travel analysts echoed the advice, recommending that travelers book fares with flexible change policies to protect against both price increases and potential flight cancellations [4].

For those with points and miles, the calculus is even clearer. ABC News travel experts suggested transferring credit card points to airlines with less dynamic pricing, such as Alaska Airlines, whose award prices are set based on flight distance rather than fuel-driven fluctuations [18].

The Bigger Picture: Inflation, Supply Chains, and a Fragile Recovery

The airfare shock is one piece of a much larger economic disruption. Beyond oil and jet fuel, the Strait of Hormuz handles roughly one-third of global fertilizer trade, one-fifth of global LNG supplies, and significant flows of petrochemical inputs, plastics, and pharmaceuticals [5]. These supply chain pressures are expected to cascade through consumer prices across the board within approximately a month [5].

Before the crisis, IATA had projected a relatively stable year for the airline industry, forecasting $41 billion in global profits and a net margin of 3.9% [8]. Those projections now appear optimistic at best. The organization had assumed crude oil prices averaging $62 per barrel for Brent — a figure that the market has blown past by 60% or more [8].

The timing is particularly cruel for consumers. The Bureau of Labor Statistics' Consumer Price Index for airline fares had been trending downward since mid-2024, when the index peaked above 320. By January 2026, it had fallen to 254.9 — a decline of more than 20% from the peak, reflecting the benefits of increased competition, capacity growth, and lower fuel costs [19]. February 2026 already showed a rebound to 263.4, and March figures, when they are released, are expected to show a significant acceleration.

What Comes Next

The trajectory of airfares depends almost entirely on the trajectory of the conflict. If the Strait of Hormuz reopens and oil prices retreat, the airline industry could absorb the shock with temporary surcharges that gradually fade. But if the closure persists — or if the conflict escalates further — the industry faces a scenario not seen since the oil crises of the 1970s.

For now, the 171 million Americans expected to fly this spring face a stark new reality: the era of cheap post-pandemic airfares, which saw real ticket prices fall to levels 37% below 2015 levels, may be over [8]. In its place is a world where a single geopolitical event halfway around the globe can double the cost of a flight to Bangkok or add $100 to a domestic roundtrip — and where the question is not whether prices will rise, but by how much and for how long.
