Delta Cuts 2026 Profit Forecast as Fuel Costs Surge

Delta Air Lines has sharply reduced its 2026 earnings outlook as surging jet fuel prices, driven by the ongoing war in Iran, put growing financial pressure on the aviation industry, despite strong passenger demand and rising ticket prices.

The Atlanta-based carrier expects annual fuel expenses to rise by about $6 billion, forcing it to cut its full-year profit forecast by nearly 25%. Delta also raised its previous estimate of additional fuel costs by $2 billion.

The announcement sent Delta shares down 2.5% in early trading, marking the airline’s first downward revision to its annual profit forecast this year.

With no clear resolution to the conflict in sight, airlines are facing their most significant financial challenges since the COVID-19 pandemic.

Delta reported third-quarter fuel expenses of $4.1 billion, a 62% increase from the same period last year and more than $500 million above its July projection.

The airline attributed the higher costs to increases in both crude oil prices and refined jet fuel prices.

“All of it is fuel,” Delta Chief Financial Officer Erik Snell told reporters when explaining the company’s reduced earnings expectations.

Delta now projects adjusted earnings of $5.10 to $5.60 per share for 2026, compared with its previous forecast of $6.50 to $7.50.

The midpoint of the revised outlook, $5.35 per share, falls below analysts’ average estimate of $5.46, according to LSEG data.

Third-quarter adjusted earnings reached $1.72 per share, slightly below the $1.76 expected by analysts. Meanwhile, the company’s adjusted operating margin declined to 9.4% from 11.1% a year earlier.

Delta’s financial challenges reflect a broader trend across the U.S. aviation sector, where fuel expenses have increased significantly throughout 2026.

According to the Bureau of Transportation Statistics, U.S. airlines spent $42.9 billion on fuel for scheduled flights during the first eight months of the year. That represents an increase of nearly $13.2 billion compared with the same period in 2025, even though airlines consumed slightly less fuel.

To offset these expenses, carriers have raised ticket prices while limiting the expansion of available seats.

U.S. airfares increased approximately 25% year over year during the five months through August, reflecting the industry’s efforts to recover higher operating costs from passengers.

Despite the increases, travel demand has remained resilient, allowing airlines to maintain relatively strong bookings.

Delta reported that nearly 60% of its fourth-quarter capacity had already been booked, indicating continued demand for air travel.

The company expects fourth-quarter revenue to increase approximately 20% compared with the same period last year.

“At the moment, those higher prices have not destroyed any demand, and it remains to be seen how long that will last,” Third Bridge analyst Liam Dorsey said.

The combination of strong passenger demand and constrained seat availability has helped airlines offset some of the pressure from fuel costs.

However, uncertainty remains over whether consumers will continue accepting higher ticket prices if fuel expenses remain elevated for an extended period.

Unlike many competing airlines, Delta operates a refinery outside Philadelphia, which helps reduce its exposure to fluctuations in jet fuel prices.

The company expects the facility to generate approximately $700 million in profit during 2026, providing a financial cushion against rising fuel expenses.

“We have a refinery that gives us an offset, a partial offset to fuel prices that no one else does,” Snell said.

Nevertheless, the refinery’s contribution is not enough to fully compensate for the sharp increase in fuel costs.

Delta expects its average fuel price to reach $4.25 per gallon in the fourth quarter, up from $3.61 in the third quarter.

The increase underscores the continuing financial impact of the geopolitical conflict on airline operations.

Although Delta continues to benefit from strong bookings and higher ticket prices, fuel expenses remain the central challenge to its profitability.

The company’s revised forecast illustrates how quickly rising energy prices can undermine airline earnings, even when passenger demand remains healthy.

For the broader aviation industry, the duration of the Iran conflict and the future direction of oil prices will be critical factors influencing operating costs and financial performance.

“Ultimately, fuel will come down. When that is, we’re not exactly sure,” Snell said.

Until energy prices stabilize, Delta and other major carriers are likely to face continued pressure on profit margins while balancing higher operating expenses against consumers’ willingness to pay more for air travel.
