Same Fuel Bill, Very Different Outcomes

Delta, absorbing what CEO Ed Bastian called “the highest quarterly fuel expense in our history,” still delivered a 9% operating margin and $1.56 EPS. United posted $10.79 in trailing EPS. American’s full-year 2026 adjusted EPS guidance was reset to a loss of $0.65 to a profit of $0.65.
