U.S. airlines are reporting stronger-than-expected travel demand heading into the spring season, supporting higher fares and revenue growth. This comes even as a surge in jet fuel prices linked to the Iran conflict has pushed operating costs higher for the industry.

Why it matters

The strong travel demand is a positive sign for the airline industry, which has faced significant headwinds from the pandemic. However, the spike in jet fuel prices, a major cost for airlines, could put pressure on profits if the elevated prices persist.

The details

Delta Air Lines said its consumer and corporate demand accelerated in March, prompting it to raise its revenue guidance for the quarter. The airline reported eight of its 10 highest sales days this quarter, including five this month following the start of the Iran conflict. JetBlue and budget carrier Frontier Airlines also reported strengthening demand, though the fuel price surge has increased their operating costs. Jet fuel prices have risen over 50% since late February, trading in a range of $150 to $200 per barrel compared to around $100 before the conflict.

  • Delta reported the strong demand acceleration in March 2026.
  • The Iran conflict that disrupted oil supplies and drove up jet fuel prices began in late February 2026.

What they’re saying

“The story for us in this quarter is about revenue demand and the health of the demand set.”

— Ed Bastian, Chief Executive Officer (J.P. Morgan industrial conference)

“Jet fuel prices have "almost doubled since the start of the year," citing a $400 million increase in fuel costs in March alone, but added that the industry is moving quickly to recoup higher expenses through fare hikes.”

— Ed Bastian, Chief Executive Officer (J.P. Morgan industrial conference)

What’s next

Airlines will likely continue to monitor the volatile jet fuel market and adjust fares and capacity accordingly to offset the higher operating costs.

The takeaway

Despite the surge in fuel costs, the strong travel demand heading into the spring season is a positive sign for the airline industry's recovery from the pandemic. However, the industry will need to carefully manage the impact of elevated fuel prices on their profitability.
