Delta Air Lines Cuts Profit Forecast as Soaring Fuel Costs Offset Strong Travel Demand

Delta Air Lines has lowered its annual profit outlook due to surging fuel costs across the aviation sector, despite continuing high demand for flights. In its third-quarter earnings report released on Friday, the Atlanta-based air carrier stated it expects annual fuel expenses to increase by $6bn, driven by ongoing tensions between the United States and Iran that have pushed global fuel prices up. Across the broader US airline industry, carriers spent nearly $43bn on fuel in the first eight months of the year, marking a $13.2bn rise compared to the same timeframe last year.

Reflecting these pressures on Wall Street, Delta reduced its full-year adjusted earnings per share forecast to a range of $5.10 to $5.60, down from its July projection of $6.50 to $7.50. This new midpoint falls short of the $5.46 average estimate compiled by LSEG data. Delta’s stock dropped 1.1 percent from Friday's opening price during midday trading. Despite a 4.4 percent decline over the past five days, the stock has experienced overall growth of nearly 18 percent since the beginning of 2026.

CEO Ed Bastian noted that the airline increased ticket prices by approximately 20 percent this year and stated those price levels could remain stable even if fuel costs drop. As the first major US carrier to report earnings, Delta benefits from relative insulation against price fluctuations thanks to its ownership of a Pennsylvania refinery acquired in 2012. Travel demand remains robust, with 60 percent of fourth-quarter flights already booked. Furthermore, Delta announced several new international routes set to launch next year, including Seattle–Tokyo, Japan, Boston–Venice, Italy, and Austin-Paris, France.

Speaking to the Wall Street Journal, Bastian confirmed that holiday bookings remain strong and premium travel continues to expand, noting an 18 percent year-over-year increase in premium seat revenue for the quarter. Data from the Airline Reporting Corporation indicates that average ticket prices for premium seats across major airlines rose 11 percent compared to the previous year.

Conversely, lower-income consumers are cutting back as overall US consumer sentiment declines, according to the University of Michigan’s Surveys of Consumers and its Consumer Sentiment Index released on Friday. Joanne Hsu, director of the Surveys of Consumers, explained that sentiment dropped steeply for lower-income consumers and those with smaller stock portfolios who possess fewer resources to absorb rising prices. This trend coincides with the end of the US summer travel season, following a Deloitte report in May revealing that 51 percent of Americans earning under $100,000 annually viewed travel as a primary expense to reduce.

United Airlines is scheduled to report its earnings next after the market closes on October 20. Mirroring Delta's market movement, United’s stock also dipped 0.8 percent on Wall Street from its Friday opening price.
