Airlines Pay $6.5 Billion in Fuel as Iran War Hits 100 Days

U.S. carriers absorbed a 78 percent year-on-year surge in fuel costs in April alone, as the conflict with Iran crosses the 100-day mark with no ceiling in sight.

U.S. airlines spent nearly $6.5 billion on fuel in April 2025.
That figure is up 26 percent from March and 78 percent from April 2024.
The spike is directly attributed to supply disruption from the ongoing war with Iran.
The conflict passed the 100-day mark with fuel markets still in adjustment.
No federal relief mechanism for carrier fuel costs has been announced.

U.S. airlines paid nearly $6.5 billion in jet fuel costs in April, a 26 percent increase from the prior month and a 78 percent increase from the same period one year ago. The war with Iran, now past the 100-day mark, is the identified driver.

The year-on-year figure is not a projection. It is the April invoice. Carriers that locked in hedging contracts before hostilities began are drawing down those positions. Carriers that did not are absorbing spot prices directly.

The $6.5 billion figure represents fuel expenditure only. It does not include rerouting costs, crew overtime for extended flight paths, or insurance premium adjustments for overflights of affected airspace. Those numbers are not yet consolidated in public reporting.

At current consumption rates, the annualized fuel cost differential — relative to pre-war baselines — is approximately $50 billion across the U.S. carrier sector. That figure will be revised as the conflict duration extends. The revision will be upward.
