US Airlines Spent over $6B on Monthly Fuel in May amid Iran War — up 84% From Year Ago

U.S. airlines spent $6.66 billion on jet fuel in May, the second straight month that fuel costs topped $6 billion, according to government data released Tuesday.

The May figure was 84% higher than a year earlier.

Airlines spent $6.47 billion on fuel in April, the Bureau of Transportation Statistics said.

The higher year-over-year spending has been driven mostly by pricier jet fuel rather than a significant increase in how much of it airlines consumed.

U.S. carriers used 1.627 billion gallons in May, down 0.6% from May 2025.

Consumption was also slightly lower in April compared with a year earlier. (Read more from “US Airlines Spent over $6B on Monthly Fuel in May amid Iran War — up 84% From Year Ago” HERE)
