Key Highlights

  • US airlines spent nearly 6.7 billion dollars on fuel in May, up 85 percent from 3.62 billion dollars a year earlier.
  • The average cost per gallon of jet fuel rose to 4.09 dollars, up 1.88 dollars from May of the prior year.
  • Jet fuel prices have since dropped roughly 40 percent from their April highs as tensions eased.
  • Oil prices rose more than 2 percent after reports of attacks on vessels near the Strait of Hormuz.

A Sharp Escalation in Fuel Expenses

US airlines faced a dramatic increase in fuel costs in May, spending nearly 6.7 billion dollars compared with 3.62 billion dollars during the same month a year earlier, an 85 percent jump driven by Middle East conflict that pushed energy prices sharply higher, according to data released by the US Transportation Department. The average cost per gallon of jet fuel reached 4.09 dollars in May, an increase of 1.88 dollars compared with the prior year period.

This followed a similarly steep increase in April, when fuel costs rose approximately 80 percent to nearly 6.5 billion dollars, illustrating the sustained pressure the conflict placed on airline operating expenses across consecutive months.

Airlines Respond With Higher Fares and Reduced Capacity

As jet fuel prices surged, major US carriers responded by raising ticket prices and baggage fees while also cutting flight schedules, measures aimed at offsetting the substantial increase in operating costs. However, these steps only partially compensated for the scale of the fuel cost increase, leaving airlines to absorb a meaningful portion of the added expense.

Delta Air Lines, United Airlines, American Airlines and Southwest Airlines, which together account for approximately 80 percent of US domestic flights, have all navigated this challenging cost environment, with airfares rising significantly since the conflict began and not yet falling back in step with recent declines in jet fuel prices.

Renewed Volatility Risk From Persian Gulf Tensions

Jet fuel prices have declined approximately 40 percent from their April highs as tensions between Iran and the United States eased in recent weeks. However, this improvement faces renewed uncertainty following reports of attacks on vessels near the Strait of Hormuz, which pushed oil prices up more than 2 percent as markets reassessed the risk of disruptions to shipping through the critical energy transit corridor.

Given the strait's importance to global energy supply chains, any escalation in tensions affecting vessel traffic through the region could quickly reverse recent fuel cost improvements, presenting airlines with renewed pressure on operating expenses even as they had begun to see some relief from the peak cost levels experienced earlier this year.

Conclusion

The sharp rise in airline fuel costs during May illustrates the significant financial exposure carriers face amid ongoing Middle East tensions, even as prices have since retreated substantially from their peak levels. Whether the recent reports of attacks near the Strait of Hormuz signal a genuine renewed escalation or an isolated incident may prove important in determining whether airlines can sustain the fuel cost relief seen in recent weeks or face another round of rising operating expenses.
