Delta Air Lines reported first-quarter revenue of $15.85 billion. This 12.9% year-over-year increase surpassed analyst expectations. Strong demand in corporate and leisure travel segments drove the growth.

The company posted a GAAP net loss of $289 million for the quarter. This compares to a net income of $240 million in the same period of 2025. Non-operating investment losses and higher operating costs drove the quarterly loss.

Rising jet fuel prices significantly impacted profitability. Delta raised checked bag fees to protect profit margins.

The airline forecasts second-quarter earnings of $1.25 per share at the midpoint. This guidance missed analyst estimates due to the elevated fuel cost environment.
