United beats Q2 estimates, warns fuel spike could add $6 billion

United Airlines topped Wall Street's second-quarter estimates on revenue and adjusted earnings, but warned that surging jet fuel prices could add nearly $6 billion to its 2026 costs. The Chicago-based carrier reported adjusted earnings of $1.99 a share on $17.67 billion in revenue for the quarter ended June 30, ahead of LSEG estimates of $1.88 a share and $17.61 billion in revenue. United forecast third-quarter adjusted earnings of $2.50 to $3.50 a share, below analysts' $3.60 estimate, and kept its full-year range at $9 to $11 a share while lifting the low end from its April outlook. It said second-quarter fuel expense jumped 84% to $2.3 billion and that higher fares and possible capacity cuts should help offset the hit.
