How the Oil Shock is Hammering Airline Stocks — And What Comes Next

Airline stocks were one of the most promising equity stories heading into 2026. The International Air Transport Association had forecast $41 billion in industry net profits for the year — a record. Then February 28 happened. The US-Israeli strikes on Iran and the subsequent effective closure of the Strait of Hormuz sent oil prices into historic territory. Brent crude closed at $112.57 per barrel on March 28, 2026 — up 51.33% from $71.24 just one month ago and the highest level since July 2022. For an industry where fuel is the single largest operating expense, that is not a headwind. It is a wall.

To understand the damage you first need to understand how structurally vulnerable airlines are to oil prices.

Fuel historically accounts for roughly a quarter to nearly a third of an airline's total cost base. There is no other expense that moves this fast or hits this hard when energy markets dislocate.

The math gets brutal quickly. Delta has previously estimated $40 million in extra annual fuel expense for every one cent move higher in jet fuel prices. With jet fuel having more than doubled in some regions since the first US-Israeli strikes on Iran on February 28, the earnings impact is not marginal — it is structural.

The cost of simply fueling a plane tells the story clearly. On February 27, the day before the attacks, filling the fuel tanks of a Boeing 737-800 cost approximately $17,000. Less than a week later on March 5, that same fill-up cost more than $27,000.

The market reaction has been swift and broad.

Year to date, Delta, American, and United have each fallen between 20% and 30%. Southwest and JetBlue have seen declines of as much as 30% over a one month period. The US Global Jets ETF, a popular gauge of airline equities, is down more than 18% over the same period.

The operational disruption compounds the financial hit. The ongoing Middle East conflict has resulted in over 20,000 grounded flights globally. Oil briefly exceeded $110 per barrel earlier this month — a level not seen since 2022.

Iran has now begun operating a yuan-based toll system at the Strait of Hormuz, allowing select Chinese, Russian, and allied vessels to transit while blocking commercial traffic broadly. The Strait has been effectively closed since March 2, disrupting approximately 17.8 million barrels per day of oil flows.

A key deadline is approaching. Trump has extended the deadline for Iran to reopen the Strait to April 6, 2026. That date is the single most important near term catalyst for airline stocks.

In previous oil shocks, airlines with strong fuel hedging programs could absorb price spikes while unhedged competitors suffered. That protection is largely absent this time.

No major US airlines currently hedge their fuel costs, meaning all are fully exposed to this price spike. American Airlines and other large carriers are among the most exposed.

Southwest, historically one of the industry's most active fuel hedgers, ended its hedging strategy entirely in 2025 — leaving it with no protection at precisely the wrong moment.

European carriers are better positioned. Ryanair has hedged 84% of its fuel needs for the first half of 2026 at $715 per metric ton, while Air France-KLM adjusted its hedging policy to cover 87% of annual fuel consumption. That buffer is providing meaningful earnings protection that US carriers simply do not have.

Delta Air Lines (DAL) — $63.44 Delta is considered better positioned than most US carriers due to its high-end demand base and premium revenue mix. Business and premium leisure travelers are less price sensitive, giving Delta more room to pass fuel costs through to fares. Delta earnings are expected April 8, with projected EPS of $0.69 and revenue of $14.93 billion for Q1 2026 — that report will be the first real data point on how badly fuel costs have hit the bottom line.

United Airlines (UAL) — $89.95 United demonstrates stronger financial health with a 5.7% trailing twelve month net margin and a more robust balance sheet, positioning it for greater resilience against operational shocks.Its international and premium mix gives it similar defensive characteristics to Delta.

American Airlines (AAL) — $10.43 American faces acute pressure with a razor thin 0.2% trailing twelve month net margin and negative book value, making its 2026 EPS target of $1.70 to $2.70 highly vulnerable to sustained fuel cost increases. The thinnest margins of the big three mean the least runway to absorb any shock.

Southwest (LUV) — $39.41 | JetBlue (JBLU) — $4.03 Both carriers have been hit particularly hard as traders punish those most exposed to domestic leisure and price-sensitive traffic — the travelers most likely to cut back when fares rise materially.

The cost pressure does not stay on Wall Street — it flows directly to consumers.

According to Skift Research, the Iran war could cost US airlines $24 billion in additional jet fuel expenses. To offset these costs airlines would need to raise ticket prices by at least 11%.

Jefferies airline analyst Sheila Kahyaoglu noted that the most acute financial impact will be felt in the next 30 to 90 days, as airlines booked yields for near term flights assuming much lower fuel prices and cannot retroactively raise fares on tickets already sold.

There is also a longer term dynamic. Research shows that while airfares rise readily with fuel costs, they do not reliably fall when fuel prices drop — a pattern attributed to industry concentration among major carriers. Travelers may see a lasting increase in the cost of flying even if the oil price shock eventually subsides.

What the data supports: The near term pain for airline stocks is real and earnings revisions are not finished. Goldman Sachs estimates a $14 to $18 per barrel geopolitical risk premium baked into current prices, warning that Brent is likely to exceed its 2008 all-time high if depressed flows keep the market focused on the risk of lengthier disruptions. Until the Strait reopens that premium stays. American Airlines is the most structurally vulnerable given its razor thin margins and zero hedging. The April 8 Delta earnings call is the first major industry data point.

What warrants monitoring: The April 6 deadline Trump set for Iran to reopen the Strait of Hormuz is the single most important near term catalyst. A diplomatic resolution before that date would likely trigger a sharp rally in airline stocks as the risk premium deflates. An extension or escalation pushes the pain deeper into peak summer travel season — the worst possible outcome for the sector.

The relative positioning: Within the sector Delta and United are better positioned than American, Southwest, and JetBlue. Premium demand is more resilient than leisure demand in a high fuel cost environment. European carriers with strong hedging books like Ryanair have a meaningful near term advantage over their unhedged US peers.
