United Airlines narrowed its profit guidance for 2025 after reporting second-quarter earnings that modestly exceeded Wall Street expectations but warning that operational constraints at its Newark Liberty hub will continue to weigh on results in the current quarter. The Chicago-based carrier now projects full-year adjusted earnings of $9 to $11 a share, tightening a previously wider range and bracketing analysts’ average estimate of $10.04. For the third quarter, it forecasts adjusted profit of $2.25 to $2.75 a share, with the midpoint coming in below the $2.60 consensus compiled by LSEG. Second-quarter adjusted earnings rose to $3.87 a share, slightly ahead of the $3.84 anticipated by analysts, helped by a pick-up in premium cabin revenue. However, the airline said flight delays and runway work at Newark—responsible for about one-fifth of its domestic capacity—sliced 1.2 percentage points from its pretax margin in the period and are set to trim a further 0.9 point in the third quarter. Chief Executive Officer Scott Kirby said booking trends have strengthened since early July, citing a six-percentage-point acceleration in overall demand and double-digit growth in corporate travel as geopolitical and economic uncertainty eases. Even so, the cautious profit outlook sent United’s shares down roughly 2% in after-hours trading.
