The airline now expects full-year results ranging from a 40-cent loss to a $1.10 profit, down from its earlier forecast of $1.10 to $2.70 in earnings per share.

"Based on the forward fuel curve and the current revenue outlook, the midpoint of the full-year guidance is expected to be approximately flat to 2025, despite a greater than $4 billion increase in expense related to higher prices for jet fuel," American stated in an earnings release.
