U.S. carrier JetBlue raised its second-quarter fuel costs forecast on Monday as shipping disruptions in the Strait of Hormuz ​entered a fourth month, increasing pressure on the global aviation industry due to ‌rising jet fuel prices.

The U.S.-Israeli attack on Iran closed the critical Strait, a vital route for nearly a fifth of global oil and gas supplies.

Jet fuel, which had averaged about 85 to 90 a barrel before the U.S. and Israeli strikes on Iran ​in February, was hovering near $`142 per barrel in the last week ⁠of May, according to the International Air Transport Association.

Fuel price volatility has ​prompted airlines across the globe to hike passenger fares and baggage fees to ​recover higher costs, as well as cut flight frequency and routes to limit fuel usage.

Higher fuel prices disproportionately pressure smaller carriers like JetBlue, given their limited financial flexibility and heightened ​vulnerability to uncertainty.

JetBlue had suspended its full-year outlook in April and said it ​planned to slow hiring, cut capacity and hike fares.

The airline now expects fuel to cost $4.26 ‌to $4.36 ⁠per gallon in the second quarter, compared to an earlier forecast between `$4.13 and $4.28.

However, JetBlue said it expects to "recapture 40% or more of increased fuel costs in the quarter," helped by consistent operational performance.

Shares of the company rose marginally before ​the bell.

The airline ​raised its forecast ⁠for revenue growth per available seat mile, a proxy for pricing power, to a range of 9% to 12%, versus ​between 7% and 11% forecast earlier.

Rival American Airlines said ​last week ⁠that it also expects strong demand to cushion the hit from rising fuel costs.

JetBlue also reported "outperformance" in routes previously operated by Spirit Airlines after the distressed carrier shut ⁠down.

"Although ​it remains early in the third quarter booking ​curve, we are encouraged current trends may carry-forward," JetBlue said in a regulatory filing.
