Turbulence Ahead: How a Geopolitical Crisis Turned the Aviation Industry Upside Down

The global airline industry entered 2026 on a wave of optimism. Passenger demand was surging, fuel costs were manageable, and the International Air Transport Association (IATA) projected record profits. Then, on February 28, joint U.S.-Israeli military strikes on Iran triggered a chain of events that sent oil prices above $100 a barrel for the first time since 2022 — and the ripple effects are now reaching every traveler's wallet.

The Spark: Strait of Hormuz and the Global Oil Shock

The crisis traces directly to the 2026 Strait of Hormuz disruption. Following the U.S.-Israeli strikes on Iran — dubbed "Operation Epic Fury" — the Islamic Revolutionary Guard Corps retaliated with missile and drone attacks and issued warnings prohibiting vessel passage through the strait [1]. Tanker traffic through the waterway, which handles roughly 20% of the world's daily oil supply, plummeted by an estimated 94%, with over 150 ships anchoring outside the strait to avoid the danger zone [2].

The consequences were immediate and severe. West Texas Intermediate (WTI) crude, which had traded in the mid-$60 range just days before the strikes, surged to $71.13 by March 2 according to Federal Reserve Economic Data, and continued climbing beyond $100 in the days that followed [3][4]. Brent crude reached $92.47, its highest level in nearly two years, and kept rising [5].

The Strait of Hormuz is not just an oil chokepoint. Approximately 30% of Europe's jet fuel supply originates from or transits through the waterway, and one-fifth of the global supply of liquefied natural gas passes through it [2]. The closure didn't just tighten crude supply — it directly disrupted the refined fuel supply chain that keeps planes in the air.

$24 Billion in New Costs: The Airlines' Fuel Crisis

Jet fuel is the lifeblood — and the single largest variable cost — of the airline industry, representing roughly "$1 out of every $5" that airlines spend, according to Skift [6]. And the price spike has been staggering.

Spot jet fuel prices at the U.S. Gulf Coast surged to $4.12 per gallon as of March 6, a level not seen in nearly four years [7]. That represents a 58% increase from the $2.50 per gallon that prevailed in late February, before the strikes began [5]. In Northwest Europe, jet kerosene prices nearly doubled, climbing from $830 per tonne to over $1,500 per tonne — an increase of roughly 80% [8].

The financial toll is enormous. Skift analysis estimates that U.S. airlines alone could face $24 billion in additional jet fuel expenses, with the global figure potentially exceeding $100 billion [6]. For perspective, the entire U.S. airline sector generated just $13.5 billion in operating profits in 2025 [6]. Every penny increase in the price of a gallon of jet fuel costs a major carrier like Delta Air Lines approximately $40 million annually, while American Airlines puts the figure at $50 million per one-percent fuel price increase [8][6].

What It Means for Your Ticket

United Airlines CEO Scott Kirby was among the first industry leaders to address the crisis publicly. Speaking at an industry event, Kirby said the fuel cost spike would have a "meaningful" impact on the carrier's financial results in Q1 2026, and warned that fare increases would "probably start quick" [5].

The math is stark: with jet fuel currently at $3.67–$4.12 per gallon against a 2025 average of $2.30, airlines need to raise average ticket prices by at least 11% simply to offset the additional fuel costs, according to Skift's analysis [6]. On intercontinental routes, the impact is already visible in surcharge structures — carrier-imposed surcharges on a business-class round-trip between the U.S. and Europe can exceed $2,000, representing 20% to 30% of the total ticket cost [9].

The timing could not be worse for consumers. Airlines are currently repricing fares for May–June 2026 travel in their revenue management systems, with July–August bookings expected to follow within two to four weeks. Formal surcharge tables are expected to be revised in April and May, meaning summer 2026 bookings made after mid-March will likely reflect the new cost reality [10].

Winners and Losers: The Hedging Divide

The crisis has exposed a stark strategic divide among the world's major carriers — one that comes down to a single question: did you hedge your fuel?

American Airlines has emerged as perhaps the most vulnerable major carrier. The company famously does not hedge its fuel costs, leaving it fully exposed to spot-market prices. Combined with a debt load of approximately $36.5 billion and razor-thin profit margins — its 2026 guidance projected adjusted earnings per share of just $1.70 to $2.70 — American is widely viewed by analysts as the airline most sensitive to energy shocks [7][11]. Its stock fell roughly 6% in the immediate aftermath of the crisis [8].

Delta Air Lines has fared relatively better, thanks in part to its strategic ownership of the Monroe Energy refinery in Trainer, Pennsylvania. This facility provides Delta with what analysts call a partial "natural hedge" against rising crack spreads, allowing the carrier to offset some of the increased cost of refined jet fuel [7]. Still, Delta's stock fell about 5.5%, and the airline's 2026 earnings forecast of $6.50–$7.50 EPS — built on the assumption of $62/barrel Brent crude — now looks precarious [11][12].

United Airlines, which had projected adjusted EPS of $12.00–$14.00 for 2026, has seen its guidance called into question as well. The carrier's stock dropped approximately 7% [8]. Kirby's candid warning about "meaningful" Q1 impact and the prospect of spillover into Q2 suggests the damage could be sustained [5].

European carriers with robust fuel-hedging programs, such as Ryanair and International Consolidated Airlines Group (parent of British Airways), may emerge as relative winners. By locking in fuel prices at lower levels, these carriers can maintain more stable pricing structures and potentially capture market share from their more exposed rivals [7]. Conversely, budget carrier Wizz Air is projecting a €50 million ($58 million) annual profit decline from the fuel surge [8].

The Industry Before the Storm: A Lost Golden Moment

What makes the current crisis especially painful is the opportunity it has disrupted. In December 2025, IATA released its most optimistic financial outlook in years, forecasting that the global airline industry would earn a combined net profit of $41 billion in 2026 — up from $39.5 billion in 2025 — on total revenues of $1.053 trillion [13]. The net profit margin was expected to stabilize at 3.9%, with 5.2 billion passengers expected to fly, a 4.4% increase [13].

Fuel costs were anticipated to actually decline slightly to $252 billion, down 0.3%, as crude oil was projected at $62 per barrel for Brent [13]. Load factors were forecast to reach record highs of 83.8%. The industry's return on invested capital was projected at 6.8% — still below the estimated cost of capital of 8.2%, but the closest the sector had come to earning its keep in years [13].

Those projections are now effectively obsolete. As one analysis put it: "$100 oil eliminates their earnings forecasts" [11].

The Stock Market Reckoning

The financial markets have delivered a swift and punishing verdict. Year-to-date, shares of Delta, American, and United have fallen between 20% and 30% [4]. Southwest Airlines, JetBlue, and Alaska Airlines experienced declines of up to 30% over just one month [4]. Airline stocks collectively endured one of their worst trading sessions in years on March 5, 2026, as the escalation sent jet fuel prices to multi-year highs [7].

The sell-off reflects more than just near-term earnings pain. Investors are repricing the sector's risk profile in an environment where geopolitical disruption can erase an entire year's worth of profits in a matter of days.

Operational Fallout: Fewer Flights, Longer Routes

The impact extends beyond balance sheets. Over 20,000 flights have been grounded due to the Middle East conflict, with airspace closures widening the disruption [4]. Airlines are reducing frequency on secondary routes to ensure every plane flies at maximum occupancy, a strategy that effectively rations capacity [14].

Some routes are seeing longer flight times as carriers detour around volatile airspace — and those longer paths burn more fuel, creating a vicious cycle of rising costs [14]. The Gulf region itself is a critical aviation hub linking Europe and Asia, and disruptions there cascade across global flight networks [2].

United Airlines reported one unexpected bright spot: a booking surge on alternative routing, with Kirby noting that "each day this week, we have booked over 1,000 people from Australia and New Zealand to Europe" via alternative connections [8].

Consumer Demand: Resilient, But for How Long?

Perhaps the most remarkable aspect of the current crisis is that travel demand, at least so far, appears to be holding. IATA data showed that global passenger demand grew 3.8% in January 2026, measured by revenue passenger kilometers [15]. The travel industry had expected 2026 to be another record year, with international airfares trending down roughly 10% for summer travel before the crisis hit [16].

But the resilience has limits. Survey data indicates that when faced with higher airfares, travelers tend to prioritize cheaper flights, shorter trips, and less expensive destinations [6]. Budget travelers — who are the most price-sensitive and the least likely to absorb fuel surcharges — will feel the pinch most acutely.

Morgan Stanley's corporate travel outlook noted that business travel demand remained solid heading into 2026, but that was based on pre-crisis assumptions [17]. If oil stays above $100 for an extended period, the demand equation will inevitably shift.

What Comes Next: SAF, Strategic Reserves, and Uncertainty

There is a grim silver lining in the crisis. The $100 oil mark may accelerate the airline industry's transition toward Sustainable Aviation Fuel (SAF). As crude prices rise, the historically wide price gap between conventional jet fuel and SAF narrows, potentially creating the economic incentive airlines need to invest more aggressively in green alternatives [14].

Governments are also weighing their options. Strategic petroleum reserves remain an available tool, and OPEC+ — which had been maintaining production discipline — faces pressure to release additional supply [18]. But even optimistic scenarios suggest that the Strait of Hormuz disruption, if it persists for weeks rather than days, could remove 8 to 10 million barrels per day from global supply [2] — a shortfall that no strategic release could fully compensate.

For now, the airline industry is caught between a geopolitical crisis it cannot control and consumers who are only willing to pay so much. The math is unforgiving: fuel costs that have nearly doubled cannot be absorbed by an industry that operates on margins below 4%. Those costs will be passed on. The only question is how quickly, and how much travel demand will bend before it breaks.
