Key Changes
-
high
Total operating revenue rose 21.1% to $20.19B, driven by broad based demand strength across premium, main, and loyalty and higher refinery sales.
-
high
Operating income declined 13.7% to $1.45B, as total operating expense jumped 25.0% to $18.73B, primarily due to higher aircraft fuel costs, expenses related to refinery sales to third parties, and salaries and related costs.
-
high
The refinery segment swung to an operating loss of $33.0M from income of $53.0M a year earlier, due to volatility in crude pricing and the negative impact from a temporary outage that halted production at the refinery beginning in the middle of June 2026.
