If WTI crude oil climbs to $100 a barrel over the next 12 months, both Delta Air Lines (DAL) and United Airlines (UAL) will see their 2026 earnings guidance evaporate, and their stocks, already down hard in 2026, will fall another 20% or more from current levels.
It’s a direct threat to guidance built on a low-fuel-cost foundation that no longer exists if oil spikes.
Reason 1: Both Airlines Guided Into a Favorable Fuel Environment That Doesn’t Hold at $100 Oil
Delta’s FY2026 EPS guidance of $6.50 to $7.50 and United’s FY2026 adjusted EPS guidance of $12.00 to $14.00 were both built on the assumption that the favorable fuel environment from 2025 continues. In 2025, Delta’s fuel expense fell 7% year-over-year, with quarterly fuel prices as low as $2.25 per gallon. United saw similar relief, with Q2 2025 fuel at $2.34 per gallon, down over 15% year-over-year. Both companies explicitly flagged fuel price volatility as a top risk. At $100 oil, those gallon prices would look nothing like 2025 — and neither would the earnings.
Reason 2: The Stocks Are Already Cracking Under Pressure
The market is already pricing in something ugly. DAL has fallen nearly 15% year-to-date, dropping from $69.22 to $59.01. UAL is down over 17% year-to-date, from $111.82 to $92.07. That’s before oil hits triple digits. The stocks are already discounting macro uncertainty — rising oil would confirm the bear case, not introduce it.
Reason 3: WTI Is Moving in the Wrong Direction
WTI crude currently sits at $71.13 per barrel as of March 2, 2026, up 10.3% in just one month from $64.50 in early February. The 12-month low was $55.44 in December 2025. That’s a $15+ recovery in under three months. Oil would need to rise another $28.87 to reach $100 — significant, but the trajectory is pointed in that direction. A geopolitical shock or supply disruption is all it takes.
Delta does own the Monroe Energy refinery, which provides some structural hedge. And analysts remain broadly bullish — 25 of 26 analysts rate DAL a buy, with a consensus target of $81.81. UAL carries 24 buy ratings and a $137.98 analyst target. Those targets assume the fuel environment cooperates.
The risk is straightforward: oil doesn’t reach $100, fuel costs stay manageable, and both airlines deliver on their guidance. In that world, DAL at $59 and UAL at $92 look cheap. But if crude keeps climbing, the guidance falls apart — and so do the stocks. The conviction here is that oil is the single variable that matters most for both names over the next 12 months, and right now it’s moving in the wrong direction.
