Delta Air Lines Cuts 2026 Profit Outlook as Fuel Costs Soar by $6 Billion
Delta Air Lines has lowered its 2026 earnings forecast after a $6 billion rise in fuel costs, even as record revenue and premium cabin demand remain strong.

Delta Air Lines has revised its 2026 profit outlook sharply downward, citing a $6 billion increase in annual fuel costs that has overwhelmed gains from record revenue and robust demand for premium travel.
The revised guidance, issued on 9 October 2026, cuts the airline's expected adjusted earnings per share to a range of $5.10 to $5.60, well below the $6.50 to $7.50 forecast it published in July. Despite the downgrade, AeroTime reports that Delta still expects to generate roughly $4.5 billion in adjusted pretax profit for the year.
What Is Driving Delta Air Lines' Revised Forecast
Chief Financial Officer Erik Snell told reporters that high jet fuel prices were the primary cause of the guidance change. Skift reports that the average fuel price stood at $4.50 per gallon as of the evening of 9 October.
Snell said Delta spent more than $500 million more on fuel in the third quarter alone than its July forecast had assumed, according to AeroTime. That overshoot, compounded across a full year, produces the $6 billion increase in the annual fuel bill compared with 2025.
For the fourth quarter, Delta expects an adjusted fuel price of approximately $4.25 per gallon, AeroTime notes, with savings of around 40 cents per gallon coming from its own refinery operation.
Record Revenue Provides Partial Cover
The fuel hit lands against a backdrop of genuinely strong trading. AeroTime reports that Delta posted record third-quarter adjusted revenue of $17.6 billion, up 16% from a year earlier, with little change in overall flight capacity.
Adjusted net income rose 2% to $1.13 billion, or $1.72 per share. Reported net income, however, fell 47% to $756 million, or $1.15 per share, with the adjusted figures excluding certain investment gains, losses and fuel-hedging items.
Higher costs reduced Delta's adjusted operating margin to 9.4% from 11.1% a year earlier. Its adjusted fuel bill increased 62% to $4.1 billion in the quarter. Non-fuel costs per available seat mile also rose 7.3%, which Delta attributed primarily to higher crew and revenue-related expenses, reduced capacity growth against original plans, and disruption from summer storms.
Premium Cabins Continue to Outperform
One of the clearest positives in the results is the sustained strength of premium demand. Revenue from premium cabins rose 18% in the third quarter, according to AeroTime. Delta offered 6% more seats in those cabins, charged higher fares and filled a greater proportion of them.
Economy also held up. Revenue per available seat mile in economy rose 17%, even as Delta reduced the total number of economy seats it offered.
Delta plans to offer slightly more seats overall in the fourth quarter, but fewer in economy, a deliberate shift toward higher-yielding cabins that the results suggest is working. Revenue is expected to rise approximately 20% in the fourth quarter.

The American Express Partnership and Fleet Deliveries
Delta's co-branded credit card partnership with American Express continues to be a significant revenue contributor. Payments from American Express increased 15% during the third quarter, AeroTime reports, putting Delta on track to receive more than $9 billion from the partnership across the full year.
On the fleet side, Delta took delivery of 13 aircraft during the quarter. Those deliveries included Airbus A350-900s, A321neos and A220-300s. You can explore Delta's fleet and route network using our Airline Search tool.
The Riyadh Question
Separate from the earnings story, Delta is facing an operational decision about its planned new non-stop service between Atlanta Hartsfield-Jackson (ATL) and Riyadh (RUH), scheduled for its inaugural flight on 23 October using an Airbus A350-900.
Paddle Your Own Kanoo reports that chief executive Ed Bastian told reporters during the investor call that the airline might not proceed with the service, following a series of missile attacks launched by Houthi rebels on Riyadh's King Khalid International Airport. When asked whether the flight would go ahead, Bastian said: "Safety is going to make the call." He was referring to Delta's internal safety and security department, which will have the final say.
Paddle Your Own Kanoo also reports that one person was killed and eight wounded in one attack on the airport earlier in the week, while on Thursday three further people were killed, including a Saudia Airlines captain, in two separate strikes. One of those strikes hit a parked Saudia Airbus A320 series aircraft at the gate, causing a fire that destroyed the fuselage. Saudi officials confirmed dozens more were wounded.
The planned 9,695 km route is part of a strategic partnership Delta announced with Riyadh Air in July 2024. The US State Department currently has Saudi Arabia under a Level 3 "Reconsider Travel" advisory, according to Paddle Your Own Kanoo.
Staff Set for Near-$900 Million Profit Share
Despite the pressure on margins, Delta's employees are set for a substantial payout. AeroTime reports that staff are on track to share nearly $900 million in profits earned during the first nine months of 2026, with payment scheduled for February 2027.
That figure, noted by Skift as well, underlines that the airline remains solidly profitable even as the fuel burden intensifies. The cuts to the earnings forecast reflect a painful external cost rather than a fundamental deterioration in demand.
The Bottom Line
Delta Air Lines is absorbing one of the largest single-year fuel cost increases any major carrier has faced in recent memory. A $6 billion rise in the fuel bill is a significant drag on any airline's finances, and the revised earnings guidance reflects that reality honestly.
The underlying business is performing well. Record revenue, strong premium cabin yields and a booming American Express partnership all point to genuine commercial health. The question for the coming months is how long fuel prices remain at these levels, and whether the Riyadh service gets off the ground at all given the security situation at King Khalid International Airport.
The long-running trend of airlines chasing premium revenue over volume, a theme we examined recently in the context of Norse Atlantic's decision to axe its New York services, is one Delta appears to be navigating more successfully than most.
