Delta Shields Margins Better Than United as Jet Fuel Costs Surge
As jet fuel prices surge, Delta Air Lines and United Airlines are demonstrating markedly different abilities to protect their profit margins, signaling divergent long-term risks for aviation investors.
Delta Air Lines and United Airlines recently reported quarterly results that highlight the severe pressure of surging jet fuel prices on airline balance sheets. Delta’s adjusted fuel price rose 75 percent year over year to $3.93 a gallon, while United’s climbed nearly 80 percent to $4.19 a gallon.
This inflation has driven significant margin compression for both carriers, though United absorbed a heavier blow. United’s adjusted earnings per share fell 48.6 percent to $1.99, and its adjusted pre-tax margin dropped over six points to 4.8 percent.
Delta demonstrated greater resilience, with adjusted earnings per share declining 26 percent to $1.56 and pre-tax margins falling four points to 7.7 percent. United’s results were also weighed down by $184 million in one-time labor contract charges this quarter.
Divergent Strategies
The divergence in financial performance stems from fundamentally different approaches to fuel cost management. While most U.S. legacy carriers have abandoned large-scale fuel hedging, Delta retains structural protection through its ownership of the Monroe Energy refinery in Pennsylvania.
The refinery supplied a meaningful share of Delta’s jet fuel needs, delivering an 11-cent-per-gallon benefit this quarter despite a temporary outage. Additionally, Delta recorded $301 million in mark-to-market hedge adjustments and settlements, offering more insulation than pure spot-market buyers.
Conversely, United is relying on balance sheet liquidity rather than derivative contracts or physical assets. Management raised $3.7 billion in new liquidity through private bank transactions this quarter, framing it as low-cost insurance against further oil spikes.
United now expects almost $6 billion in incremental fuel expense for the full year 2026, up from its original budget. Its select fuel supply contracts fall well short of the comprehensive hedging programs utilized by European carriers or Delta’s refinery model.
Passing the Cost
Both airlines have so far succeeded in passing these higher costs to consumers without crushing demand. United grew capacity 3.5 percent year over year while lifting adjusted unit revenue by 12.1 percent, whereas Delta grew capacity roughly 1 percent and pushed unit revenue up 12.4 percent.
Notably, both carriers reported strong growth in their cheapest cabins, challenging the narrative of a pullback in budget-conscious leisure travel. United’s overall economy-cabin unit revenue rose 12 percent, and Delta’s main cabin ticket revenue increased 8 percent.
This dynamic likely reflects a market share shift rather than a broad demand surge. As ultra-low-cost carriers struggle with their own economics, price-sensitive travelers are migrating to the lower-tier fare products offered by legacy networks.
For investors, the contrasting strategies present distinct risk profiles. United may offer more short-term upside if travel demand remains robust, but Delta’s integrated hedging strategy provides superior long-term margin protection.
Reinforcing its commitment to shareholder returns, Delta recently increased its dividend by approximately 15 percent to $0.2150 per share. This dividend is scheduled for payment on July 30, 2026, to shareholders of record as of July 9.
