Airlines in Turbulence: Who Wins in the 2026 Oil Shock?

 The “Strait of Hormuz” premium has shifted from a theoretical risk to a structural reality, though the narrative has taken a sudden turn. After Brent crude touched $120/barrel and global jet fuel prices surged to levels equivalent to $180–$210/barrel in some regions, oil prices plunged by nearly 15% this morning (dropping below $95). This follows President Trump’s announcement of a provisional two-week ceasefire and the subsequent reopening of the Strait of Hormuz. 

For retail investors, this volatility has created a sharp divide between carriers with structural insulation and those facing high-beta exposure. The upcoming earnings calls will reveal the true depth of the headwinds faced during the peak of the disruption and who is best positioned to capitalize on this morning’s sudden relief. 

Oil Shock 2026: A Strategic Audit of Airline Earnings 

For retail investors, the 2026 earnings season is not just about passenger demand—which remains at record levels—but about how business models absorb sudden, geopolitically driven cost shocks. 

1. Delta Air Lines (DAL): The Integrated Supply Chain Model

Delta’s primary differentiator remains the Trainer Refinery (Monroe Energy) in Pennsylvania. 

• The Reality: The refinery is a strategic asset designed to blunt the volatility of “crack spreads”—the cost difference between crude oil and jet fuel. While it does not insulate Delta from rising crude prices, it provides a physical hedge that competitors lack. 

• The Strategy: In periods where jet fuel prices spike faster than crude, the refinery acts as a natural stabilizer. For 2025, Delta reported a “refinery benefit” of 11¢ per gallon in the December quarter. As jet fuel has surged to roughly $4.81/gallon (Argus US Index) this April, this benefit can widen if refining margins expand. 

• Earnings Focus: Watch for the “Refinery Segment” results today. If Delta maintains its double-digit 2026 EPS growth guidance despite the war, it could suggest that that physical integration alongside demand, pricing power and cost control forms a good defense against energy volatility. 

2. United Airlines (UAL): Operational Flexibility & Yield Management

United represents the industry’s response to rising costs through operational agility rather than financial hedging. 

• The Reality: United has historically maintained zero financial hedging, preferring to manage oil shocks via ticket pricing and capacity adjustments. CEO Scott Kirby has recently indicated willingness for the carrier to “cut unprofitable flights” over the next two quarters to protect margins as they prepare for sustained high oil prices. 

• The Strategy: United is combatting the fuel shock by pulling the “revenue lever.” They have already announced a $10 increase in checked bag fees and are raising fares—which have climbed year-over-year industry-wide as of this week. 

• Earnings Focus: Monitor Load Factors. The risk for United is “demand destruction”—the point where ticket prices become too high that passengers stop booking. If United reports strong yields without a drop in volume, their operational flexibility is working. 

3. Singapore Airlines (SIA): Financial Hedging and Hub Resilience

SIA remains the defensive benchmark for Singapore-based investors due to its consistent use of financial derivatives. 

• The Reality: SIA is currently one of the most protected carriers globally. Analysts (CGS International) report that SIA has typically hedged 40 to 60% of its fuel requirements for the April–June 2026 quarter. This coverage is slated to decline to 34% in the following quarter and 24% for the six months after. 

• The Strategy: This “financial armor” provides massive near-term earnings visibility. While SIA expects to book “large hedging gains” this quarter, the challenge remains long-term but keep a lookout for analysts adjustments as they factor in the impact and changes in oil prices.  

• Earnings Focus: Watch for commentary on “yield pass-through.” SIA is forecasted to only be able to offset about 75% of the fuel increase through higher fares, meaning some margin compression is inevitable despite the hedges. 

4. Southwest Airlines (LUV): The Transition to Spot Exposure

Southwest provides the most critical contrast in this cycle due to a major policy shift it made right as the conflict began. 

• The Reality: In a move that has drawn intense scrutiny, Southwest ended its long-standing fuel hedging program in early 2025. This has left the carrier fully exposed to volatile spot prices just as jet fuel has surged by 106% in a single month. 

• The Strategy: Southwest’s 2026 earnings projections were based on a fuel price of $2.405 per gallon—a figure that now sits nearly $2.00 below the current spot market. To compensate, Southwest has secured a $500 million term loan and is pivoting to new revenue streams, including assigned seating and basic economy. 

• Earnings Focus: Watch for a “Margin Warning.” Southwest is the most vulnerable of the majors to a direct profit crunch. If they cannot implement rapid “revenue initiatives” to offset the fuel spike, their 2026 earnings targets will likely be retracted.  

The Bottom Line: In this “Oil Shock” environment, the market will reward predictability. SIA and Delta offer the most structural protection, while United is a leveraged play on resilient travel demand despite higher fares. In contrast, Southwest stands out as the most vulnerable, given its full exposure to volatile fuel prices.

This divergence is exactly where opportunity emerges. As oil prices swing and airline strategies separate winners from laggards, investors are presented with a clearer framework to position around strength, resilience, and risk. Whether you’re looking at global carriers like Delta and United or regional leaders like Singapore Airlines, staying ahead of these shifting dynamics is key to capturing alpha.
