CHICAGO, Sept 16 (Reuters) – American Airlines CEO Robert Isom said on Wednesday that persistently high fuel prices could force the carrier to adjust capacity, even as strong demand ​and revenue gains have helped offset much of the higher cost.

Speaking ‌at a Morgan Stanley conference, Isom said he felt “really good” about American’s third-quarter revenue growth forecast of 16% to 19% and expected the vast majority of the recent revenue gains to prove durable.

The comments highlight the pressure on airlines as another jump in fuel prices tests ‌how ​much of the higher cost can continue to be ⁠offset through stronger revenue.

American says ⁠it has recaptured a substantial portion of the increase so far, but the latest spike is now prompting capacity adjustments for the late fourth quarter.

Isom said revenue strength was broad-based across domestic and international markets and both ​premium and coach cabins. He said American had already recaptured “a tremendous amount” of the higher fuel expense through revenue.

He described the current year-over-year revenue improvement ⁠as unlike anything he had seen in ⁠his career, outside of recoveries following the COVID-19 pandemic and ​the September 11 attacks.

FUEL SPIKE ADDS PRESSURE

Speaking at the same conference, American Airlines’ chief ​financial officer, Devon May, said fourth-quarter fuel prices had risen roughly $1 ‌a gallon from the level assumed when American issued its guidance in July, adding about $1 billion to the carrier’s fuel costs.

May said every 1-cent move in fuel prices changes American’s quarterly costs by about $10 million. The airline would continue adjusting ⁠capacity late in the fourth quarter because of the increase, he said.

The latest fuel spike has had its biggest impact on the fourth-quarter outlook. May said July and ⁠August fuel prices were ‌broadly in line with American’s third-quarter assumptions before rising ⁠in September.

American’s third-quarter revenue, capacity and unit-cost performance otherwise remained ​in ‌line with expectations, May said, leaving fuel as the main ​variable in ⁠the outlook.

Asked whether the fuel increase could force American to lower its full-year guidance or result in negative free-cash flow, May said the carrier would monitor how fuel prices settle over the next several weeks and provide fourth-quarter guidance when it reports earnings.
