Airlines Adjust Revenue Forecasts Amid Rising Fuel Costs Linked to Iran Conflict

In response to escalating jet fuel prices due to the ongoing conflict in Iran, Delta Air Lines and American Airlines have both raised their revenue forecasts for the first quarter of 2026. This adjustment comes despite the significant financial impact of increased fuel costs, which each airline estimates at approximately $400 million.

Delta Air Lines has revised its revenue growth outlook to a high-single-digit percentage, up from an initial estimate of 5% to 7%. The airline anticipates total revenue between $15 billion and $15.3 billion for the quarter. CEO Ed Bastian noted that demand has remained robust, with bookings up 25% year-over-year, and highlighted that eight of the top ten sales days in the airline's history occurred this quarter.

American Airlines has also increased its revenue expectations, projecting a growth of over 10% year-over-year, surpassing its previous guidance of 7% to 10%. This marks the highest quarterly revenue growth in the airline's history. CEO Robert Isom stated that the revenue growth is "incredibly strong" and is expected to continue throughout the year.

The surge in jet fuel prices, which have increased by more than 50% since late February due to military actions involving the U.S. and Israel against Iran, has significantly affected operational costs for airlines. Current jet fuel prices range between $150 and $200 per barrel, compared to approximately $100 per barrel before the conflict began. Fuel costs typically account for 20% to 25% of total operating expenses for airlines, making this increase particularly impactful.

Despite these challenges, both Delta and American Airlines have maintained their profit projections for the quarter. Delta continues to target adjusted earnings per share between 50 cents and 90 cents.

While the airlines have reported strong demand, some analysts suggest that budget carriers may face more severe repercussions from rising fuel costs compared to airlines with a customer base skewed toward premium and corporate travel. This perspective indicates a potential disparity in how different segments of the airline industry are affected by the current economic climate.
