US airline stocks soar as carriers report record revenue growth despite fuel costs

US airline stocks rose sharply on Tuesday after several carriers reported stronger-than-expected revenue growth. The gains came as a relief, reversing recent losses linked to rising fuel costs following the Iran conflict. Executives from major airlines shared updated forecasts at the JPMorgan Industrials Conference in Washington.

Delta Air Lines led the positive updates, raising its first-quarter revenue outlook to high-single-digit growth—up from an earlier estimate of 5-7%. CEO Ed Bastian highlighted robust demand from both leisure and business travellers heading into March. The airline's shares climbed around 5% in morning trading.

American Airlines also revised its projections, now expecting at least a 10% revenue increase for Q1. This would mark the largest year-over-year quarterly revenue jump in the company's history. Its stock rose by roughly 2.7%. JetBlue similarly lifted its unit revenue guidance to 5-7% growth, a significant improvement from near-flat expectations. The airline attributed the boost to strong travel demand, which helped counterbalance higher fuel costs and winter weather disruptions. Frontier Airlines also saw gains, with shares rising about 7.5%. Despite the positive revenue news, United Airlines CEO Scott Kirby warned of a short-term spike in airfares. He cited rising jet fuel costs as the primary driver. Meanwhile, American Airlines' CEO had previously stated on March 17, 2026, that fuel price surges from the Iran conflict would push the carrier into a Q1 loss.

The updated forecasts and stock gains signal resilience in air travel demand, even as fuel costs remain a challenge. Airlines like Delta and American now project record revenue growth for the quarter. The market response suggests investor confidence in the sector's ability to manage rising expenses.
