Delta Air Lines carries passengers across the United States and internationally. Passenger travel supplies most of its revenue, with U.S. routes contributing the largest share. Travelers pay for main-cabin seats or premium options such as Delta One and Delta Premium Select; both main-cabin and premium tickets are major sources of income.
Its SkyMiles program also turns customers’ everyday spending into cash for Delta. American Express and other partners buy miles to award to their customers, who can redeem them for flights, upgrades and other rewards. American Express supplies nearly all cash sales under these loyalty marketing agreements, making card spending and new cardholder sign-ups important to this business.
Delta also owns Monroe Energy’s Trainer refinery, which supplies jet fuel for its airline and sells non-jet products to third parties. This supports fuel supply and helps offset the refining cost embedded in jet-fuel prices, but does not insulate Delta from changes in fuel prices or availability.
International airline partnerships extend Delta’s network and allow coordinated schedules, pricing and revenue sharing. Those arrangements depend on regulatory permission. A U.S. order terminating antitrust immunity for its cooperation with Aeroméxico is stayed pending court review, allowing the partners to continue operating under the agreement while the stay remains in effect.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Delta’s international results also depend on coordinated networks and shared route economics with Air France, KLM, Virgin Atlantic and Korean Air, none of which appears in this list.
United Airlines competes with Delta for domestic, international and corporate travelers, with both selling flights through global hub networks. United’s network and schedule changes show where Delta faces competition for those passengers.
American Airlines Group competes with Delta for connecting passengers, corporate accounts and loyalty customers, selling domestic and international flights through large hub networks. Watch its fares and connecting schedules for the alternatives it offers Delta’s customers.
American Express pays Delta for miles and co-branded card benefits—$8.2 billion in 2025—linking Delta’s income to a card business that earns mainly from spending. Spending on Delta-branded cards and new cardholder sign-ups are the key signals for Delta’s loyalty revenue.
Southwest sells flights to domestic passengers who can also choose Delta, making its fares and seat capacity relevant to Delta’s largest passenger market. Watch its domestic flight additions and pricing for changes in that competition.
Alaska Air Group’s passenger airlines compete with Delta, which names Alaska Airlines as a domestic rival. Passenger transportation accounted for 90% of the group’s 2025 revenue, making that revenue line the clearest view of its competing airline business.
JetBlue competes with Delta for paying travelers in New York, Boston and Los Angeles, including premium coast-to-coast and transatlantic flights. Its Mint lie-flat service is a concrete product to watch against Delta’s premium offerings.
LATAM and Delta share revenue or profits on covered North–South America routes and coordinate seats and pricing; Delta also owns approximately 11% of LATAM. Watch LATAM’s flights between the two continents, where passenger demand reaches their shared route results.
Delta pays SkyWest to operate regional flights that bring small- and medium-sized U.S. city passengers into Delta’s network; SkyWest operated approximately 680 daily Delta Connection departures at year-end 2025. Its flight completion and staffing show its ability to deliver that connecting service.
Aeroméxico and Delta coordinate flights for U.S.–Mexico travelers, and Delta owns approximately 19% of Aeroméxico’s parent. Watch the court case over their permission to coordinate: a November 2025 stay allowed the agreement to continue while the challenge to the termination order remained unresolved.
Delta pays Republic Airways Holdings Inc. to fly regional services while Delta sells the tickets and keeps the associated revenue; Republic had 57 operational aircraft allocated to Delta at year-end 2025. That allocated fleet is a concrete measure of the regional flying Republic supplies to Delta’s network.
Frontier’s low-fare domestic flights compete for Delta’s price-sensitive passengers and add to the capacity pressure on main-cabin fares. It mainly sells leisure travelers a base ticket with paid extras; watch its fares and seat capacity against Delta’s domestic main-cabin weakness.
Delta depends on Boeing to supply aircraft it buys for its fleet, including 30 contracted 787-10s scheduled to start arriving in 2031. Watch progress toward those deliveries as Delta replaces older aircraft with more fuel-efficient planes offering more premium seats and cargo space.
Delta relies on GE Aerospace for aircraft engines, including the GEnx engines selected for its contracted Boeing 787-10s. GE sells engines and earns from maintenance and spare parts afterward, making GEnx production and support the relevant business to watch for Delta’s future fleet.
EIA Crude Oil Stocks Change (Oct/16)
For Delta, the EIA’s weekly stocks report tracks crude oil and fuel held in storage, which signals supply conditions that can move market-index fuel prices and the airline’s fuel bill.
Expected-0.3MLast release-8.557M
If it comes in above expectations
If the reading is above the -0.3M estimate, it is above the previous -8.557M. Larger stocks can signal looser supply and put downward pressure on oil and fuel prices, potentially reducing what Delta pays for fuel; smaller stocks can tighten supply and raise that cost.
If it comes in below expectations
Smaller stocks can signal tighter supply and put upward pressure on oil and fuel prices, potentially raising what Delta pays for fuel; larger stocks can loosen supply and lower that cost.
American Express Company earningsAXP
American Express’s report will show how co-branded card spending and new accounts are developing, offering a read on an important source of Delta’s loyalty income.
Watch spending on Delta-branded cards and new cardholder sign-ups. Strength in both would show that more cardholders are using the relationship, supporting Delta’s loyalty income; weakness in either or both would mean less support from card spending or the growth of the cardholder base.
Boeing Company earningsBA
Boeing’s report will show how aircraft production and deliveries are progressing, relevant to Delta’s plan to renew its fleet and add premium seats and cargo capacity.
Watch Boeing’s production progress and delivery performance. Steady progress would support Delta’s plan to replace aircraft with more fuel-efficient planes offering more premium seats and cargo space; setbacks would leave that fleet-renewal plan more exposed to delivery delays. Boeing’s overall results alone cannot confirm the delivery timing of any specific Delta aircraft.
Fed Interest Rate Decision
For Delta, the Fed’s policy rate sets the broader cost of borrowing, which can change interest paid on variable-rate debt and the cost of refinancing or taking on new debt.
Expected4.0%Last release4.0%
If it comes in above expectations
Higher rates can raise interest costs on debt that reprices and make refinancing or new borrowing more expensive, leaving less cash for Delta’s operations and investment.
If it comes in below expectations
Lower rates can reduce interest costs on debt that reprices and make refinancing or new borrowing cheaper, leaving more cash available for Delta’s operations and investment.
Skywest Inc earningsSKYW
SkyWest’s report will show whether it can reliably operate the regional flights Delta relies on to connect small and mid-sized cities to its network.
Look at SkyWest’s staffing and flight completion. Adequate crews and reliable flights would keep passengers from small and mid-sized cities connected to Delta’s hubs; weaker staffing or completion would disrupt regional links and reduce the flow of those passengers into Delta’s network.
LATAM Airlines Group S.A. earningsLTM
LATAM’s report will show how passenger demand and flying are developing on North–South America routes where it coordinates seats and shares revenue or profits with Delta.
Look at LATAM’s traffic and flying on North–South America routes. Strong traffic with steady service would show that travelers support the routes the partners operate together, giving Delta a stronger base for its shared-revenue or profit arrangement; weaker traffic would shrink the business supporting that partnership.
Delta Air Lines, Inc. earningsThis company
Delta’s report will show whether premium-cabin and loyalty revenue can offset weaker main-cabin results and keep pace with added capacity.
Compare passenger revenue growth with growth in available seat miles, then check premium and main-cabin yield. Revenue growing faster than capacity, with premium yield still stronger than main-cabin yield, would show that added seats and higher-priced products are both bringing in money. Revenue lagging capacity, especially with weaker main-cabin results, would mean expansion is not converting into enough revenue and Delta is relying more on premium demand.
