Delta Cuts Full-Year Earnings Forecast on 62% Fuel Cost Surge

Delta Air Lines reported third-quarter earnings that missed analyst expectations, with adjusted earnings per share of $1.72 versus a forecast of $1.82, and adjusted revenue of $17.58 billion against estimates of $17.76 billion. The airline attributed the shortfall primarily to a sharp increase in jet fuel costs, which reached $4.1 billion in Q3 alone—a 62% increase from the prior year. Delta's Q3 performance was reduced by $500 million in higher fuel costs than anticipated when the airline issued guidance in July.

In response, Delta cut its full-year adjusted earnings per share forecast to $5.10–$5.60 from a prior range of $6.50–$7.50. The company also reduced its free cash flow forecast to $2.5 billion from $3.0–$4.0 billion. CEO Ed Bastian stated that Delta expects to generate a pre-tax profit of roughly $4.5 billion while absorbing a $6 billion increase in fuel costs for the full year. CFO Erik Snell indicated that fuel costs are expected to remain elevated in the quarter ahead.

Delta attributed the elevated fuel prices to geopolitical tensions in the Middle East affecting global oil markets. Despite the fuel headwinds, the airline noted that strong demand in its premium business segment helped offset some of the impact. Delta's premium business grew 18% year-over-year in Q3, with loyalty and related revenue also up 18%, and American Express credit card remuneration growing 15% and on track to exceed $9 billion for the full year.

The guidance cut reflects mounting pressure on the airline industry as a whole, with smaller carriers facing even greater difficulty weathering spiraling fuel costs. Delta remains focused on profitable growth and its long-term financial framework, which targets mid-teens margins and returns, durable free cash flow, and gross leverage of approximately one times. The company plans to grow capacity by 2% going forward, a reversal from earlier guidance in 2026.
