Delta Air Lines delivered Q2 2026 GAAP net income of $1.6 billion despite absorbing its largest quarterly fuel bill, with jet fuel prices climbing to $3.66 per gallon from $2.21. Operating revenue surged 19% year-over-year to $19.8 billion, driven by $1.7 billion higher passenger revenue across premium, main cabin, and corporate segments. Non-GAAP operating income matched the GAAP net figure at $1.6 billion, yielding an 8.8% margin while CASM-Ex rose 6.8% to 14.09¢. The carrier reaffirmed full-year adjusted EPS guidance of $6.50–$7.50, targeting 20% year-over-year growth, and expects double-digit operating margins in the second half. Net income declined 25% from $2.1 billion, yet free cash flow reached $1.4 billion in the first half, underscoring resilience against a multi-billion dollar fuel headwind.
